      y.io.graphml.graph2d.ReadNodeRealizerHandler

All Implemented Interfaces:

InputHandler

public class ReadNodeRealizerHandler
extends AbstractInputHandler

Input handler for NodeRealizer data attributes in GraphML.

Constructor Summary

ReadNodeRealizerHandler()

Method Summary

boolean	acceptKey(Element keyDefinition)
void	applyDefault(GraphMLParseContext context) This method is invoked when no data tag is defined, and the default value should be applied.
protected Object	parseDataCore(GraphMLParseContext context, Node node) Abstract method callback that actually parses the data.
protected void	setValue(GraphMLParseContext context, Object key, Object data) Abstract method callback that actually stores the value with the keys.

Method Detail

acceptKey

public boolean acceptKey(Element keyDefinition)

parseDataCore

protected Object parseDataCore(GraphMLParseContext context,
                               Node node)
                        throws GraphMLParseException

Description copied from class: AbstractInputHandler

Abstract method callback that actually parses the data.

Specified by:

parseDataCore in class AbstractInputHandler

Throws:

GraphMLParseException

Parameters:

context - The context.

node - The node that contains the data. This is either the GraphML data element or the default element.

Returns:

The parsed data.

setValue

protected void setValue(GraphMLParseContext context,
                        Object key,
                        Object data)

Description copied from class: AbstractInputHandler

Abstract method callback that actually stores the value with the keys.

Specified by:

setValue in class AbstractInputHandler

Parameters:

context - The context.

key - The key.

data - The data.

applyDefault

public void applyDefault(GraphMLParseContext context)

Description copied from class: AbstractInputHandler

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

This implementation delegates to AbstractInputHandler.setValue(GraphMLParseContext, Object, Object). if AbstractInputHandler.isDefaultExists()

Specified by:

applyDefault in interface InputHandler

Overrides:

applyDefault in class AbstractInputHandler

Parameters:

context - the current parse context.
