TestCompressor

public TestCompressor()

Method Detail

compress

public int[] compress(VRMLNodeType ifs)

Compress the given geometry.

Specified by:

compress in interface NodeCompressor

Parameters:

ifs - The geometry to compress

Returns:

An int array for the geometry

decompress

public void decompress(int[] data)

Decompress the data into a geometry.

Specified by:

decompress in interface NodeCompressor

Parameters:

data - The compressed data

Returns:

The X3D node

handleData

public boolean handleData(java.lang.String nodeName,
                          java.lang.String fieldName)

Checks whether this compressors handles this data. If not then the data should be written to the stream.

Specified by:

handleData in interface NodeCompressor

Parameters:

nodeName - the node

fieldName - the field

fillData

public void fillData(java.lang.String nodeName,
                     BinaryContentHandler ch)

Fill in the data handled by the compressor.

Specified by:

fillData in interface NodeCompressor

Parameters:

nodeName - The nodeName

getEncoderMetadata

public java.lang.String getEncoderMetadata()

Get any metadata the encoder would like to write to the file.

Specified by:

getEncoderMetadata in interface NodeCompressor

Returns:

The metadata in X3D XML encoding

observedNode

public void observedNode(VRMLNodeType parent,
                         VRMLNodeType child,
                         int field,
                         boolean used)

Notification of a child node.

Specified by:

observedNode in interface SceneGraphTraversalSimpleObserver

Parameters:

parent - The parent node of this node

child - The child node that is being observed

field - The index of the child field in its parent node

used - true if the node reference is actually a USE
