public class J3DBuffer extends java.lang.Object
Java 3D wrapper class for java.nio.Buffer objects. When used to wrap a non-null NIO buffer object, this class will create a read-only view of the wrapped NIO buffer, and will callrewind
on the read-only view, so that elements 0 throughbuffer.limit()-1
will be available internally.- Since:
- Java 3D 1.3

Constructor Detail
-
J3DBuffer
public J3DBuffer()
Constructs a J3DBuffer object and initializes it with a null NIO buffer object. The NIO buffer object must be set to a non-null value before using this J3DBuffer object in a Java 3D node component.- Throws:
java.lang.UnsupportedOperationException
- if the JVM does not support native access to direct NIO buffers
-
J3DBuffer
public J3DBuffer(java.nio.Buffer buffer)
Constructs a J3DBuffer object and initializes it with the specified NIO buffer object.- Parameters:
buffer
- the NIO buffer wrapped by this J3DBuffer- Throws:
java.lang.UnsupportedOperationException
- if the JVM does not support native access to direct NIO buffersjava.lang.IllegalArgumentException
- if the specified buffer is not a direct buffer, or if the byte order of the specified buffer does not match the native byte order of the underlying platform.

buffer
- the NIO buffer wrapped by this J3DBuffer- Throws:
java.lang.IllegalArgumentException
- if the specified buffer is not a direct buffer, or if the byte order of the specified buffer does not match the native byte order of the underlying platform.
