Method Summary

Modifier and Type	Method and Description
void	addNamedEventHandler(Asn1NamedEventHandler handler) This method adds a named event handler to the named event handler list for this buffer.
int	getEventHandlerListCount() This method returns number of elements in the event handler list in this object.
abstract java.io.InputStream	getInputStream() This abstract method must be implemented by all of the derived classes.
boolean	hasEventHandlers() This method returns true if, the buffer has event handlers set.
void	invokeCharacters(java.lang.String svalue) This method is used by the event handling logic to invoke the 'characters' event handling method when message contents are parsed.
void	invokeEndElement(java.lang.String name, int index) This method is used by the event handling logic to invoke the 'endElement' event handling method when parsing of an element within a message is completed.
void	invokeStartElement(java.lang.String name, int index) This method is used by the event handling logic to invoke the 'startElement' event handling method when parsing of an element within a message is started.
void	setEventHandlerList(Asn1MessageBuffer buffer) This method will set the event handler dispatcher in this object to be equal to that in the given decode buffer object (the buffers will share the dispatcher).

Method Detail

getInputStream

public abstract java.io.InputStream getInputStream()

This abstract method must be implemented by all of the derived classes. It returns an input stream object reference to the message buffer contents (i.e. the encoded data).

Returns:

Input stream object reference

addNamedEventHandler

public void addNamedEventHandler(Asn1NamedEventHandler handler)

This method adds a named event handler to the named event handler list for this buffer.

Parameters:

handler - Asn1NamedEventHandler object to be added

getEventHandlerListCount

public int getEventHandlerListCount()

This method returns number of elements in the event handler list in this object.

Returns:

number of elements in the event handler list.

hasEventHandlers

public final boolean hasEventHandlers()

This method returns true if, the buffer has event handlers set.

Returns:

true, if the buffer has event handlers. false, otherwise.

invokeCharacters

public void invokeCharacters(java.lang.String svalue)

This method is used by the event handling logic to invoke the 'characters' event handling method when message contents are parsed. It uses the type code last set by Asn1MessageBufferBase.setTypeCode(short)

Parameters:

svalue - Stringified representation of a parsed value field

invokeEndElement

public void invokeEndElement(java.lang.String name,
                             int index)

This method is used by the event handling logic to invoke the 'endElement' event handling method when parsing of an element within a message is completed.

Parameters:

name - Name of the element

index - Index of element if SEQUENCE OF or SET OF element

invokeStartElement

public void invokeStartElement(java.lang.String name,
                               int index)

This method is used by the event handling logic to invoke the 'startElement' event handling method when parsing of an element within a message is started.

Parameters:

name - Name of the element

index - Index of element if SEQUENCE OF or SET OF element

setEventHandlerList

public void setEventHandlerList(Asn1MessageBuffer buffer)

This method will set the event handler dispatcher in this object to be equal to that in the given decode buffer object (the buffers will share the dispatcher).

Parameters:

buffer - Decode buffer object
