Method Detail

compileToPush

public void compileToPush(CompilerService compiler,
                          Expression expression)
                   throws CannotCompileException

Description copied from class: ExpressionCompiler

Generate bytecode to evaluate the expression in push mode Precondition: none. Postcondition: at execution time, the stack is unchanged, and the value of the expression has been written to the current receiver

Overrides:

compileToPush in class ToIteratorCompiler

Parameters:

compiler - the compiler service

expression - the expression to be compiled

Throws:

CannotCompileException - if the expression cannot be compiled to bytecode

compileCopyNamespace

protected static void compileCopyNamespace(CompilerService compiler,
                                           Expression expression,
                                           int selectedItemVar)

compileCopyText

protected static void compileCopyText(CompilerService compiler,
                                      Expression expression,
                                      int selectedItemVar)
