Constructor Summary

DVMBinaryNode(byte[] value)
Creates a BINARY node with the specified value.

DVMBinaryNode(byte[] value, Locator loc, boolean isShared)
Creates a BINARY node and sets its associated locator and isShared status.

Method Summary

boolean	equals(Object o) Only equal if object is a Node with the same type and same value.
String	getAttribute(String attrName) Always null.
String[]	getAttributeNames() Empty array.
List<Attribute>	getAttributes() Empty list.
byte[]	getBytes() Returns the data of this BINARY node.
