All Implemented Interfaces:

DOMInputHandler

public class NodeInsetsInputHandler

extends AbstractDOMInputHandler

Input handler that parses node insets for group nodes and stores the insets in the GroupingKeys.GROUP_NODE_INSETS_DPKEY data provider.

Constructor Summary

NodeInsetsInputHandler()

Method Summary

boolean	acceptKey(NamedNodeMap attributes, int scopeType) This method defines whether a specific key/data pair is handled by the input handler.
protected void	applyDefault(DOMGraphMLParseContext context, Graph graph, Object nodeedge) Apply default data.
protected void	parseData(DOMGraphMLParseContext context, Graph graph, Object nodeedge, boolean defaultMode, Node domNode) Parses the data.

Method Detail

parseData

protected void parseData(DOMGraphMLParseContext context,
                         Graph graph,
                         Object nodeedge,
                         boolean defaultMode,
                         Node domNode)

Parses the data.

Parameters:

context - The context in which the parser is.

graph - The current graph in the parse context.

nodeedge - The current node/edge in the parse context.

defaultMode - Whether default data or real data is read.

domNode - The DOM node which is actually processed.

applyDefault

protected void applyDefault(DOMGraphMLParseContext context,
                            Graph graph,
                            Object nodeedge)

Apply default data.

Parameters:

context - The context in which the parser is.

graph - The current graph in the parse context.

nodeedge - The current node/edge in the parse context.

acceptKey

public boolean acceptKey(NamedNodeMap attributes,
                         int scopeType)

This method defines whether a specific key/data pair is handled by the input handler. When it returns true, each occurence of data elements which match the id of the key element are forwarded to the input handler.

Parameters:

attributes - the attributes of the key tag.

scopeType - the scope for which the key is defined. One of GraphMLConstants.SCOPE_ALL, GraphMLConstants.SCOPE_EDGE, GraphMLConstants.SCOPE_ENDPOINT, GraphMLConstants.SCOPE_GRAPH, GraphMLConstants.SCOPE_NODE, GraphMLConstants.SCOPE_PORT, GraphMLConstants.SCOPE_HYPEREDGE.
