PropagateSegment Class |
Namespace: AGI.Foundation.SegmentPropagation
The PropagateSegment type exposes the following members.
Name | Description | |
---|---|---|
PropagateSegment(StoppablePropagatorDefinition) |
Initializes a new instance with a StoppablePropagator.
| |
PropagateSegment(PropagateSegment, CopyContext) | Initializes a new instance as a copy of an existing instance. |
Name | Description | |
---|---|---|
AllowZeroElements |
Gets a value indicating whether if it is acceptable for this type of PropagateSegment to
have no elements. By default this is false.
| |
Elements |
Gets the names of all of the elements that this segment is propagating.
(Inherited from SegmentDefinition.) | |
IsFrozen |
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an
ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.) | |
MaximumDuration |
Gets or sets the maximum Duration that this segment may propagate before being stopped.
The sign of this Duration will be changed at configuration time to match this segments
PropagationDirection. By default this is set to 100 days.
| |
Name |
Gets or sets a name to describe the segment. This is optional.
(Inherited from SegmentDefinition.) | |
NextStateBehavior |
Gets or sets the behavior for passing states to the next segment. See StateForNextSegmentBehavior for more information.
(Inherited from SegmentDefinition.) | |
OutputSparsity |
Gets or sets the interval at which to produce output samples.
By default this is set to one, meaning that output will be saved in the state history
for every integration step. If a thinner (but less accurate) ephemeris is desired you can set this
to a higher number. Two means that output is saved every other integration step, etc, etc.
| |
PassAllElementsToNextSegment |
Gets a value indicating whether the segment is such that it will not define any Elements or
StateElementAdapters. Such a segment typically
affects the control flow of multiple segments instead of propagating state elements. By default this is
, but if the specific derived segment can use the previous segment's adapters,
override this property to always return . Even if this is
some segments may require adapters to be set with the
SetElementAndAdapter(StateElementAdapterDefinition) method.
(Inherited from SegmentDefinition.) | |
PropagationDirection |
Gets or sets the direction that this segment will be initially propagated. If this segment propagates
multiple segments, the child segments will be propagated in the direction that they are configured with.
If the overall list is going forward, segments that go back in time will override the immediate previous
segments ephemeris, but if another segment going forward follows the backwards segment, that backwards
segment will be ignored when the overall trajectory is resolved into a single ephemeris set. If you are using a
StoppingCondition that depends on time, the time span of
those stopping conditions must match this property (for example, a
DurationStoppingCondition must have a negative
threshold if this is set to Decreasing,
otherwise, the condition will never be tripped).
(Inherited from SegmentDefinition.) | |
StopOnMaximumDurationBehavior |
Gets or sets what should be done if the span of propagation exceeds the MaximumDuration.
By default this will stop all propagation and immediately return the results computed up to this point.
| |
StoppablePropagator |
Gets or sets the StoppablePropagatorDefinition that will be
propagated by this segment. Note that the adapters on the
StoppablePropagatorDefinition will be automatically set by
this segment. Segments that derived from PropagateSegment
may set this, but it is often easier to expose the relevant properties on this
than to expose it directly.
| |
StoppingConditions |
Gets the stopping conditions that may stop this segment.
Only one StoppingCondition needs to be satisfied to stop propagation. If by the
very rare chance that two conditions happens to stop at the exact same time, the one
earlier in this list will be the one that was reported to have stopped propagation.
Note that this property returns the
conditions on the
StoppablePropagator. This
will be until the StoppablePropagator is initialized.
|
Name | Description | |
---|---|---|
CheckForSameDefinition(DefinitionalObject) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from SegmentDefinition.) | |
CheckForSameDefinition(PropagateSegment) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
| |
CheckForSameDefinition(SegmentDefinition) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides SegmentDefinitionCheckForSameDefinition(SegmentDefinition).) | |
ClearStoppingConditionsAutoSegment |
Removes the optional segment that would have been run if the
specified StoppingCondition would stop propagation. This method will return
if the stoppingCondition has no optional segment.
| |
Clone |
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).) | |
ComputeCurrentDefinitionHashCode |
Computes a hash code based on the current properties of this object. Derived classes MUST override this
method and compute a hash code that combines: a unique hash code seed, the base implementation result, and
the hash codes of all new fields introduced by the derived class which are used in the
CheckForSameDefinition(DefinitionalObject) method.
(Overrides SegmentDefinitionComputeCurrentDefinitionHashCode.) | |
ContainsElement |
Checks to see if there is a StateElementAdapterDefinition for the provided
element.
(Inherited from SegmentDefinition.) | |
CreateSegmentPropagator |
Creates, configures, and returns the SegmentPropagator for this
segment. This method should check that all of the required properties on the
concrete instance are configured properly before constructing the
SegmentPropagator to be returned.
(Overrides SegmentDefinitionCreateSegmentPropagator(EvaluatorGroup, SegmentDefinition).) | |
EnumerateDependencies |
Enumerates the dependencies of this object by calling
EnumerateT(T) for each object that this object directly depends upon.
Derived classes which contain additional dependencies MUST override this method, call the base
implementation, and enumerate dependencies introduced by the derived class.
(Overrides DefinitionalObjectEnumerateDependencies(DependencyEnumerator).) | |
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
Freeze |
Freezes this object. Further attempts to modify it will result
in an ObjectFrozenException.
(Inherited from DefinitionalObject.) | |
FreezeAggregatedObjects |
Called by Freeze to also freeze any objects that are considered to be a part of this object.
Derived classes which contain additional aggregated objects MUST override this method, call the base
implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be
frozen in this method are frequently created in this object's constructor and are not settable via
properties.
(Overrides DefinitionalObjectFreezeAggregatedObjects.) | |
GetDefinedIn |
Gets the object (for example, a ReferenceFrame, an Axes, etc.)
in which the specified element is defined in. This can return if there
is no such object. When overriding this method, you generally should not call the base method,
instead the derived segment should keep track of the elements and defined in objects itself.
(Inherited from SegmentDefinition.) | |
GetDefinitionHashCode |
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.) | |
GetElementAdapter |
Returns the adapter for the given state element. The
StateElementAdapters handle the various
transformations of the propagated elements between segments (for example, if
the integration frame of a point being propagated changes
from one segment to another, the
adapter is what handles that transformation between
segment). All elements propagated by this segment must have
an adapter returned by this method (even if that adapter
simply returns the original state).
If multiple segments are being propagated by this segment (as a SegmentList would), this
must return the adapter of the StateElementAdapter of the element for the final
known segment getting propagated.
(Inherited from SegmentDefinition.) | |
GetHashCode | Serves as the default hash function. (Inherited from Object.) | |
GetNumberOfTimesToExecuteStoppingConditionsAutoSegment |
Returns the number of times the auto-segment associated
with the stoppingCondition is set to execute. If the
stoppingCondition does not have a SegmentDefinition associated
with it, then 1 will be returned.
| |
GetSegmentPropagator |
Creates, configures, and returns the SegmentPropagator for this
segment. This method assumes that no previous segment is needed to configure
this segment's propagator.
(Inherited from SegmentDefinition.) | |
GetSegmentPropagator(EvaluatorGroup) |
Creates, configures, and returns the SegmentPropagator for this
segment. This method assumes that no previous segment is needed to configure
this segment's propagator.
(Inherited from SegmentDefinition.) | |
GetSegmentPropagator(SegmentDefinition) |
Creates, configures, and returns the SegmentPropagator for this
segment.
(Inherited from SegmentDefinition.) | |
GetSegmentPropagator(EvaluatorGroup, SegmentDefinition) |
Creates, configures, and returns the SegmentPropagator for this
segment.
(Inherited from SegmentDefinition.) | |
GetStoppingConditionsAutoSegment |
Returns the SegmentDefinition that is set to be run if the
specified stoppingCondition stops propagation,
or if there has not been such a segment specified.
| |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IsSameDefinition |
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
RemoveElement |
Removes the StateElementAdapterDefinition for the specified element.
(Inherited from SegmentDefinition.) | |
SetElementAndAdapter | Add or sets an adapter for an element in this segment. Note that many types of derived segments will automatically handle their adapters by interrogating properties specific to the derived segment. Also some segments whose PassAllElementsToNextSegment property is do not require adapters or elements to be set. These adapters have the responsibility of processing the initial state that the propagator will start propagating from. They will modify the initial state passed to this segment so that the state is in a form that the propagator can process. | |
SetStoppingConditionAutoSegment |
Each StoppingCondition in the StoppingConditions can have a
SegmentDefinition associated with it that will be propagated if that
StoppingCondition happens to be the one that stops this segments propagation. Use this
method to set that optional segment.
| |
ThrowIfFrozen |
Throws ObjectFrozenException if this object IsFrozen.
This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObject.) | |
ToString | Returns a string that represents the current object. (Inherited from SegmentDefinition.) |
Name | Description | |
---|---|---|
PropagationFinishedEvent |
An event that gets raised when propagation is complete.
(Overrides SegmentDefinitionPropagationFinishedEvent.) | |
StepTaken |
An event that will be raised every time a step is taken by the underlying
StoppablePropagator.
|
Consider deriving from this type when the specific StoppablePropagatorDefinition can be used to handle the configuration of the StateElementAdapters or other book-keeping needed for the segment. Note that although the derived definition can limit what type of StoppablePropagatorDefinition is used, you should still use the SegmentPropagator that the PropagateSegment creates.
The results returned when this segments propagator is propagated will always be a PropagateSegmentResults.
