Specified by:

getKeyDefinitionAttributes in interface OutputHandler

Overrides:

getKeyDefinitionAttributes in class AbstractOutputHandler

Returns:

the key definition attributes for edge layout information.

writeValueCore

protected void writeValueCore(GraphMLWriteContext context,
                              java.lang.Object data)
                       throws GraphMLWriteException

Calls context.serialize(data) for EdgeLayout data.

Specified by:

writeValueCore in class AbstractOutputHandler

Parameters:

context - The current serialization context.

data - The EdgeLayout instance to serialize.

Throws:

GraphMLWriteException - if a problem occurs during serialization.

getValue

protected java.lang.Object getValue(GraphMLWriteContext context,
                                    java.lang.Object key)

Retrieves the EdgeLayout instances associated to the specified key edge.

Specified by:

getValue in class AbstractOutputHandler

Parameters:

context - The current serialization context.

key - The Edge instance that is serialized.

Returns:

the EdgeLayout instances associated to the specified key edge.
