Constructor Detail

SinglePointStoppablePropagatorDefinition

protected SinglePointStoppablePropagatorDefinition()

Initializes a new instance.

SinglePointStoppablePropagatorDefinition

protected SinglePointStoppablePropagatorDefinition(@Nonnull
                                                   SinglePointStoppablePropagatorDefinition existingInstance,
                                                   @Nonnull
                                                   CopyContext context)

Initializes a new instance as a copy of an existing instance.

See ICloneWithContext.clone(CopyContext) for more information about how to implement this constructor in a derived class.

Parameters:

existingInstance - The existing instance to copy.

context - A CopyContext that controls the depth of the copy.

Throws:

ArgumentNullException - Thrown when existingInstance or context is null.

Method Detail

checkForSameDefinition

protected final boolean checkForSameDefinition(StoppablePropagatorDefinition other)

Checks to determine if another instance has the same definition as this instance and returns true 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 false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Overrides:

checkForSameDefinition in class StoppablePropagatorDefinition

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

checkForSameDefinition

protected boolean checkForSameDefinition(SinglePointStoppablePropagatorDefinition other)

Checks to determine if another instance has the same definition as this instance and returns true 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 false for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IEquatableDefinition.isSameDefinition(java.lang.Object).

Parameters:

other - The other instance to compare to this one.

Returns:

true if the two objects are defined equivalently; otherwise false.

computeCurrentDefinitionHashCode

protected int 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 SinglePointStoppablePropagatorDefinition.checkForSameDefinition(agi.foundation.propagators.StoppablePropagatorDefinition) method.

Overrides:

computeCurrentDefinitionHashCode in class StoppablePropagatorDefinition

Returns:

The computed hash code.

enumerateDependencies

public void enumerateDependencies(DependencyEnumerator enumerator)

Enumerates the dependencies of this object by calling DependencyEnumerator#enumerate(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.

Specified by:

enumerateDependencies in interface IEnumerateDependencies

Overrides:

enumerateDependencies in class StoppablePropagatorDefinition

Parameters:

enumerator - The enumerator that is informed of the dependencies of this object.

getPropagationFrame

public final ReferenceFrame getPropagationFrame()

Gets the ReferenceFrame to propagate in. This should be an inertial reference frame.

setPropagationFrame

                                 JulianDate value)

getAutomaticallyAddEndOfAvailabilityStoppingConditions

public final boolean getAutomaticallyAddEndOfAvailabilityStoppingConditions()
