All Implemented Interfaces:

SceneGraphTraversalSimpleObserver, BinaryContentHandler, ContentHandler, ProtoHandler, RouteHandler, ScriptHandler, StringContentHandler

public class X3DBinaryRetainedDirectExporter
extends X3DRetainedSAXExporter
implements SceneGraphTraversalSimpleObserver

X3D binary exporter using a retained Scenegraph. This will directly write to X3D binary instead of reusing the XML code to generate an XML file in memory. Known Issues: Proto node fields are copied into instances

public X3DBinaryRetainedDirectExporter(OutputStream os,
 int major,
 int minor,
 org.j3d.util.ErrorReporter errorReporter,
 int compressionMethod,
 float quantizeParam,
 boolean oldMethod)

Create a new exporter for the given spec version

Method Details

setMinFloatArraySizeToEncode

public void setMinFloatArraySizeToEncode(int len)

Set the minimum float length array to using deltazlib encoding. Under a certain length the algorithm increases size. This could be calculated but the runtime cost is pretty high.

Parameters:

len -

encodeDoubleArray

protected void encodeDoubleArray(double[] fval,
 int numElements,
 VRMLFieldDeclaration decl,
 String qName,
 com.sun.xml.fastinfoset.sax.AttributesHolder aholder,
 int ftype)

Encode double array data. This base version will just use a string rep.

Overrides:

encodeDoubleArray in class X3DRetainedSAXExporter

Parameters:

fval - The parsed double array value

numElements - The number of elements per item

decl - The field declaration.

qName - The qualified name

aholder - The current attributes holder

ftype - The X3D field type, defined in FieldConstants

encodeFloatArray

protected void encodeFloatArray(float[] fval,
 int numElements,
 VRMLFieldDeclaration decl,
 String qName,
 com.sun.xml.fastinfoset.sax.AttributesHolder aholder,
 int ftype)

Encode float array data. This base version will just use a string rep

Overrides:

encodeFloatArray in class X3DRetainedSAXExporter

Parameters:

fval - The parsed float array value

numElements - The number of elements per item

decl - The field declaration.

qName - The qualified name

aholder - The current attributes holder

ftype - The X3D field type, defined in FieldConstants
