extends mxObjectCodec

Codec for mxCells. This class is created and registered dynamically at load time and used implicitely via mxCodec and the mxCodecRegistry.

Field Summary

Fields inherited from class com.mxgraph.io.mxObjectCodec
`exclude, idrefs, mapping, reverse, template`

Constructor Summary
`mxCellCodec()` Constructs a new cell codec.
`mxCellCodec(java.lang.Object template)` Constructs a new cell codec for the given template.
`mxCellCodec(java.lang.Object template, java.lang.String[] exclude, java.lang.String[] idrefs, java.util.Map<java.lang.String,java.lang.String> mapping)` Constructs a new cell codec for the given arguments.

Method Summary
`org.w3c.dom.Node` `afterEncode(mxCodec enc, java.lang.Object obj, org.w3c.dom.Node node)` Encodes an mxCell and wraps the XML up inside the XML of the user object (inversion).
`org.w3c.dom.Node` `beforeDecode(mxCodec dec, org.w3c.dom.Node node, java.lang.Object obj)` Decodes an mxCell and uses the enclosing XML node as the user object for the cell (inversion).
`boolean` `isExcluded(java.lang.Object obj, java.lang.String attr, java.lang.Object value, boolean write)` Excludes user objects that are XML nodes.

Constructor Detail

### mxCellCodec

    public mxCellCodec()

  Constructs a new cell codec.

### mxCellCodec

    public mxCellCodec(java.lang.Object template)

  Constructs a new cell codec for the given template.

### mxCellCodec

    public mxCellCodec(java.lang.Object template,
                       java.lang.String[] exclude,
                       java.lang.String[] idrefs,
                       java.util.Map<java.lang.String,java.lang.String> mapping)

  Constructs a new cell codec for the given arguments.

Method Detail

### isExcluded

    public boolean isExcluded(java.lang.Object obj,
                              java.lang.String attr,
                              java.lang.Object value,
                              boolean write)

  Excludes user objects that are XML nodes.

  Overrides:
    `isExcluded` in class `mxObjectCodec`
  Parameters:
    `obj` - Object instance that contains the field.
    `attr` - Fieldname of the field.
    `value` - Value of the field.
    `write` - Boolean indicating if the field is being encoded or decoded. write is true if the field is being encoded, else it is being decoded.
  Returns:
    Returns true if the given attribute should be ignored.

### afterEncode

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

  Encodes an mxCell and wraps the XML up inside the XML of the user object (inversion).

  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 obj)

  Decodes an mxCell and uses the enclosing XML node as the user object for the cell (inversion).

  Overrides:
    `beforeDecode` in class `mxObjectCodec`
  Parameters:
    `dec` - Codec that controls the decoding process.
    `node` - XML node to be decoded.
    `obj` - Object to encode the node into.
  Returns:
    Returns the node used for the default decoding.
