Enclosing class:

XMLDataNode

protected static final class XMLDataNode.DataCastPacket

extends java.lang.Object

The DataCastPacket class is a data class that is helpful for reducing the number of type-cast operations that need to occur. This is done by replacing the type-cast check with a check for null at the expense of keeping around more references in memory to the object in question.

This kind of strategy works well for objects that are frequently cast to a particular type. Once it has been created, this class is an immutable (read-only) data structure.
