Interface EncoderFactory

All Known Implementing Classes:

DefaultEncoderFactory, HierarchicGraphEncoderFactory

public interface EncoderFactory

This interface is a factory for ObjectEncoders. It is used by the GMLIOHandler to encode valid GML.

Method Summary

ObjectEncoder	createEdgeEncoder(ObjectEncoder graphEncoder) create an encoder that is capable of encoding an edge
ObjectEncoder	createGMLEncoder() return an Encoder, that is capable of writing the gml header
ObjectEncoder	createGraphEncoder(ObjectEncoder gmlEncoder) create an encoder that is capable of encoding a graph
ObjectEncoder	createNodeEncoder(ObjectEncoder graphEncoder) create an encoder that is capable of encoding a node
