Class StateElementAdapterDefinition

java.lang.Object

agi.foundation.infrastructure.DefinitionalObject

agi.foundation.coordinates.StateElementAdapterDefinition

All Implemented Interfaces:

ICloneWithContext, IEnumerateDependencies, IEquatableDefinition, IFreezable

Direct Known Subclasses:

DoNothingStateElementAdapter, SimpleAdapter, SimpleMotionAdapter, TransformationalStateElementAdapterDefinition

public abstract class StateElementAdapterDefinition
extends DefinitionalObject

Adapters are the objects that link up an element from one form of propagation to another. For example, when the ReferenceFrame changes for a PropagationPointElement from one SegmentPropagator to the next, an adapter can be made that can retrieve the needed information from the two segments.

Constructor Detail

StateElementAdapterDefinition

protected StateElementAdapterDefinition()

Initializes a new instance.

StateElementAdapterDefinition

protected StateElementAdapterDefinition(@Nonnull
                                        StateElementAdapterDefinition 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(DefinitionalObject 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).

Specified by:

checkForSameDefinition in class DefinitionalObject

Parameters:

other - The other instance to compare to this one.

Returns:

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

checkForSameDefinition

protected abstract boolean checkForSameDefinition(StateElementAdapterDefinition 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 StateElementAdapterDefinition.checkForSameDefinition(agi.foundation.infrastructure.DefinitionalObject) method.

Overrides:

computeCurrentDefinitionHashCode in class DefinitionalObject

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 DefinitionalObject

Parameters:

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

getElementIdentification

public final String getElementIdentification()

Gets the identification of the element in the state that will be adapted.

setElementIdentification

public final void setElementIdentification(String value)

Sets the identification of the element in the state that will be adapted.

getAdapter

@Nonnull
public abstract StateElementAdapter getAdapter(@Nullable
                                                         StateElementAdapterDefinition previousAdapter,
                                                         @Nonnull
                                                         EvaluatorGroup group)

Creates the adapter defined by this instance. Since adapters are meant to transition from one context to another, the previous adapter is passed in to finish the configuration. If it is not needed for your particular adapter it can be ignored.

Parameters:

previousAdapter - The properly configured previous adapter. Implementations of this method should be able to handle cases where the previousAdapter is of the same or compatible type. For example, a ReferenceFrameAdapter must be able to handle when another ReferenceFrameAdapter is passed in as the previousAdapter. If the types are incompatible, then this method should throw an exception as it is a sign that something is incorrectly configured. When possible, design your adapters to work properly even if this parameter is null. Consider adding extra properties to the derived type, or have a well defined default behavior if the previousAdapter is null.

group - The EvaluatorGroup to use when constructing any needed evaluators.

Returns:

The configured StateElementAdapter.
