Method Detail

afterEncode

public org.w3c.dom.Node afterEncode(mxCodec enc,
                                    java.lang.Object obj,
                                    org.w3c.dom.Node node)

Description copied from class: mxObjectCodec

Hook for subclassers to post-process the node for the given object after encoding and return the post-processed node. This implementation returns the input node. The return value of this method is returned to the encoder from . Parameters:

Overrides:

afterEncode in class mxObjectCodec

Parameters:

enc - Codec that controls the encoding process.

obj - Object to be encoded.

node - XML node that represents the default encoding.

Returns:

Returns the resulting node of the encoding.

beforeDecode

public org.w3c.dom.Node beforeDecode(mxCodec dec,
                                     org.w3c.dom.Node node,
                                     java.lang.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.

afterDecode

public java.lang.Object afterDecode(mxCodec dec,
                                    org.w3c.dom.Node node,
                                    java.lang.Object obj)

Description copied from class: mxObjectCodec

Hook for subclassers to post-process the object after decoding. This implementation returns the given object without any changes. The return value of this method is returned to the decoder from mxObjectCodec.decode(mxCodec, Node).

Overrides:

afterDecode in class mxObjectCodec

Parameters:

dec - Codec that controls the decoding process.

node - XML node to be decoded.

obj - Object that represents the default decoding.

Returns:

Returns the result of the decoding process.
