Constructor Detail

### LocalVariable

    public LocalVariable()

Method Detail

### processLeavingTail

    public TailCall processLeavingTail(XPathContext context)
                                throws XPathException

  Process the local variable declaration

  Specified by:
    `processLeavingTail` in interface `TailCallReturner`
  Specified by:
    `processLeavingTail` in class `Instruction`
  Parameters:
    `context` - The dynamic context of the transformation, giving access to the current node, the current variables, etc.
  Returns:
    null if the instruction has completed execution; or a TailCall indicating a function call or template call that is delegated to the caller, to be made after the stack has been unwound so as to save stack space.
  Throws:
    `XPathException`

### evaluateVariable

    public ValueRepresentation evaluateVariable(XPathContext c)
                                         throws XPathException

  Evaluate the variable

  Throws:
    `XPathException`
