ArgumentNullException - Thrown when existingInstance or context is null.

Method Detail

checkForSameDefinition

protected final boolean checkForSameDefinition(ObjectExtension 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 ObjectExtension

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(BaseTransmittingAntennaExtension<TGainPattern> 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 BaseTransmittingAntennaExtension.checkForSameDefinition(agi.foundation.infrastructure.ObjectExtension) method.

Overrides:

computeCurrentDefinitionHashCode in class ObjectExtension

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 ObjectExtension

Parameters:

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

getInputSignalProcessor

public SignalProcessor getInputSignalProcessor()

Gets the signal processor which produces the set of signals to transmit through the antenna.

Specified by:

getInputSignalProcessor in interface ISignalToTransmitService

setInputSignalProcessor

public void setInputSignalProcessor(SignalProcessor value)

Sets the signal processor which produces the set of signals to transmit through the antenna.

getPolarizationSource

public final PolarizationSource getPolarizationSource()

Gets the polarization source.

setPolarizationSource

public final void setPolarizationSource(PolarizationSource value)

Overrides:

getService in class ObjectExtension

Parameters:

serviceType - An object that specifies the type of service object to get.

Returns:

The found service, or null if the service does not exist.

                                                      Vector reflectedVector,
                                                      SignalPropagationGraph graph)
