mxModelCodec

public mxModelCodec(Object template,
                    String[] exclude,
                    String[] idrefs,
                    Map<String,String> mapping)

Method Detail

encodeObject

protected void encodeObject(mxCodec enc,
                            Object obj,
                            Node node)

Encodes the given mxGraphModel by writing a (flat) XML sequence of cell nodes as produced by the mxCellCodec. The sequence is wrapped-up in a node with the name root.

Overrides:

encodeObject in class mxObjectCodec

Parameters:

enc - Codec that controls the encoding process.

obj - Object to be encoded.

node - XML node that contains the encoded object.

beforeDecode

public Node beforeDecode(mxCodec dec,
                         Node node,
                         Object into)

Reads the cells into the graph model. All cells are children of the root element in the node.

Overrides:

beforeDecode in class mxObjectCodec

Parameters:

dec - Codec that controls the decoding process.

node - XML node to be decoded.

into - Object to encode the node into.

Returns:

Returns the node used for the default decoding.
