Class PostprocessorInputHandler

java.lang.Object
  y.io.graphml.graph2d.PostprocessorInputHandler

All Implemented Interfaces:

InputHandler

Deprecated. Client code should explicitly implement post-processing steps.

public class PostprocessorInputHandler
extends java.lang.Object
implements InputHandler

This input handler parses end executes postprocessor instructions specified in GraphML files at graph scope.

Field Summary

static java.lang.String

IGNORE_POSTPROCESSOR_ERRORS Deprecated.

Constructor Summary

PostprocessorInputHandler()
Deprecated.

Method Summary

boolean	acceptKey(org.w3c.dom.NamedNodeMap map) Deprecated. Accepts keys at graph scope whose attribute yfiles.type has the value postprocessors.
void	applyDefault(GraphMLParseContext context) Deprecated. This method is invoked when no data tag is defined, and the default value should be applied.
ParsePrecedence	getPrecedence() Deprecated. Gets the parse precedence that is associated with this instance.
protected YModule	newModule(java.lang.String moduleName, GraphMLParseContext context) Deprecated. Creates a YModule instance that is used as a post-processor.
void	parseData(GraphMLParseContext context, org.w3c.dom.Node node) Deprecated. Parses and executes postprocessing instructions.
protected void	startModule(YModule module, Graph2D graph, GraphMLParseContext context) Deprecated. Starts the given module with the given graph.

PostprocessorInputHandler

public PostprocessorInputHandler()

Deprecated.

Method Detail

acceptKey

public boolean acceptKey(org.w3c.dom.NamedNodeMap map)

Deprecated.

Accepts keys at graph scope whose attribute yfiles.type has the value postprocessors.

parseData

public void parseData(GraphMLParseContext context,
                      org.w3c.dom.Node node)
               throws GraphMLParseException

Deprecated.

Parses and executes postprocessing instructions.

Specified by:

parseData in interface InputHandler

Parameters:

context - The context in which the parser is.

node - The DOM node which is actually processed.

Throws:

GraphMLParseException

newModule

protected YModule newModule(java.lang.String moduleName,
                            GraphMLParseContext context)
                     throws java.lang.Exception

Deprecated.

Creates a YModule instance that is used as a post-processor.

The default implementation assumes a public, non-argument constructor in the requested module class.

Note: To prevent obfuscation from breaking post-processing support, an explicit name mapping should be specified for class names of modules that are used as post-processors.

Parameters:

moduleName - the external name identifing the module to instantiate.

Throws:

java.lang.Exception

See Also:

NameMapper, PostprocessorOutputHandler.encodeType(YModule, GraphMLWriteContext)

startModule

protected void startModule(YModule module,
                           Graph2D graph,
                           GraphMLParseContext context)
                    throws GraphMLParseException

Deprecated.

Starts the given module with the given graph. This method is called from parseData for each parsed post-processor module.

Parameters:

module - The module to start.

graph - The graph to pass to the module.

context - The context in which the parser is.

Throws:

GraphMLParseException - if an exception is thrown by running the module.

getPrecedence

public ParsePrecedence getPrecedence()

Deprecated.

Description copied from interface: InputHandler

Gets the parse precedence that is associated with this instance.

Specified by:

getPrecedence in interface InputHandler

Returns:

The parse precedence for this instance.

applyDefault

public void applyDefault(GraphMLParseContext context)

Deprecated.

Description copied from interface: InputHandler

This method is invoked when no data tag is defined, and the default value should be applied.

Specified by:

applyDefault in interface InputHandler

Parameters:

context - the current parse context.
