public interface VariableDeclaration
Generic interface representing a variable declaration in the static context of an XPath expression.
The declaration may be internal or external to the XPath expression itself. An external
VariableDeclaration is identified (perhaps created) by the bindVariable() method in the StaticContext.

Method Details
-
registerReference
Method called by a BindingReference to register the variable reference for subsequent fixup. This method is called by the XPath parser when each reference to the variable is encountered. At some time after parsing and before execution of the expression, the VariableDeclaration is responsible for calling the two methods setStaticType() and fixup() on each BindingReference that has been registered with it. -
