callBuilder

public TemplateProcessor callBuilder(TemplateBuilder builder)
                              throws ParseException

A TemplateBuilder can call this method to have an Instruction call it back to be built. This implementation calls the TemplateBuilder.buildStatement(EmptyInstruction) method, passing back a reference to itself. This approach is intended to make type-checking of Instruction objects unnecessary.

Specified by:

callBuilder in interface Instruction

Parameters:

builder - the builder to be called back by this method

Throws:

ParseException
