Class MarshalData

java.lang.Object
  org.eclipse.hyades.execution.invocation.MarshalData

Direct Known Subclasses:

CallData, ReturnData

public abstract class MarshalData

extends java.lang.Object

This is the supertype of classes that are essentially data holders that are used during the marshalling and unmarshalling of data that is to be sent between processes in support of remote method invocation semantics. The state of MarshalData instances is intended to be immutable. It should only be set during instantiation, by the constructors provided. The intention is to prevent invalid data combinations.

Field Summary

protected java.lang.Class[]	argTypes the argument types of the method that is to be or has already been invoked
protected java.lang.String	call the name of the method that is to be or has already been invoked
protected java.lang.Integer	targetId the unique id associated with the object on which some action is to be performed

Constructor Summary

protected

MarshalData(java.lang.Integer targetId, java.lang.Class[] argTypes, java.lang.String call)

Method Summary

java.lang.Class[]	getArgTypes() Get the argument type list of the method that is to be or already has been invoked.
java.lang.String	getCall() Get the name of the method that is to be or already has been invoked.
java.lang.Integer	getTargetId() Get the unique id associated with the target instance -- the object on which some action is to be performed.
boolean	isForSameCallAs(MarshalData comp) Determine if this instance was created for the same method call as the specified instance.

Method Detail

getTargetId

public java.lang.Integer getTargetId()

Get the unique id associated with the target instance -- the object on which some action is to be performed.

Returns:

an Integer

isForSameCallAs

public boolean isForSameCallAs(MarshalData comp)

Determine if this instance was created for the same method call as the specified instance.

Parameters:

comp - a MarshalData instance

Returns:

true if this instance was created for the same method call as that for which comp was created, false otherwise
