Field Detail

pathHandler

protected PathHandler pathHandler

The path handler used to report parse events.

Constructor Detail

PathParser

public PathParser(PathHandler handler)

Creates a new PathParser.

Method Detail

setPathHandler

public void setPathHandler(PathHandler handler)

Allows an application to register a path handler.

If the application does not register a handler, all events reported by the parser will be silently ignored.

Applications may register a new or different handler in the middle of a parse, and the parser must begin using the new handler immediately.

Parameters:

handler - The transform list handler.

getPathHandler

public PathHandler getPathHandler()

Returns the path handler in use.
