public Interface ExpressionNode

extends SourceLocator
Known Direct Implementers
com.sun.org.apache.xpath.internal.Expression
Imports
javax.xml.transform.SourceLocator
A class that implements this interface can construct expressions, give information about child and parent expressions, and give the originating source information. A class that implements this interface does not lay any claim to being directly executable.

Note

This interface should not be considered stable. Only exprSetParent and exprGetParent can be counted on to work reliably. Work in progress.
