Class ComponentBinding

java.lang.Object
net.sf.saxon.expr.ComponentBinding
public class ComponentBinding extends Object
A ComponentBinding is a reference from one component to another; for example a variable reference or function call. ComponentBindings are held in the binding vector of the calling component, and are separate from the instruction/expression that contains the reference, to provide a level of indirection; this means that when a component is re-bound in a using package, for example to call overriding versions of templates or functions called from the component, the compiled code of the calling component does not need to be changed, only the contents of the binding vector.

The ComponentBinding class is immutable.
