Interface VariableDeclaration

All Known Implementing Classes:
GlobalVariableDefinition, JAXPVariable, UndeclaredVariable, XPathVariable, XSLParam, XSLVariable, XSLVariableDeclaration

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 Summary

    Modifier and Type
    Method
    Description
    Get the name of the variable as a structured QName
    void
    Method called by a BindingReference to register the variable reference for subsequent fixup.
  • Method Details

    • registerReference

      void registerReference(BindingReference ref)
      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.
      Parameters:
      ref - the variable reference
    • getVariableQName

      StructuredQName getVariableQName()
      Get the name of the variable as a structured QName
      Returns:
      the variable name
