marshallExchangeSpecificElements

public void marshallExchangeSpecificElements(FormatWriter mFormat)
                                      throws FormatException

Description copied from class: Exchange

This method is utilized by the derived classes to marshall (or serialize) elements that are specific to the derived class. All the base class elements (which are identified by the accessor methods) are handled by the base class even though it is an abstract class.

Specified by:

marshallExchangeSpecificElements in class Exchange

Parameters:

mFormat - The buffer formatter to write to.

Throws:

FormatException

unmarshallExchangeSpecificElements

public void unmarshallExchangeSpecificElements(FormatReader mFormat)
                                        throws FormatException

Description copied from class: Exchange

This method is utilized by the derived classes to reconstruct elements that are specific to the derived class. The unmarshall method will reconstruct the object state based on what was marshalled using the marshall method. All the base class elements (which are identified by the accessor methods) are handled by the base class even though it is an abstract class.

Specified by:

unmarshallExchangeSpecificElements in class Exchange

Parameters:

mFormat - The buffer formatter to read from.

Throws:

FormatException
