ToPushCompiler
public ToPushCompiler()
compileToIterator
public void compileToIterator(CompilerService compiler,
Expression expression)
throws CannotCompileException
- Description copied from class:
ExpressionCompiler
- Generate bytecode to evaluate the expression as a
SequenceIterator
Precondition: none.
Postcondition: at execution time, the stack contains a SequenceIterator representing the result of the expression
- Specified by:
compileToIterator
in class ExpressionCompiler
- Parameters:
compiler
- the compiler serviceexpression
- the expression to be compiled
- Throws:
CannotCompileException
compileToItem
public void compileToItem(CompilerService compiler,
Expression expression)
throws CannotCompileException
- Description copied from class:
ExpressionCompiler
- Generate bytecode to evaluate the expression as an Item
Precondition: none.
Postcondition: at execution time, the stack contains either an item (the result of the expression), or null
(representing an empty sequence).
- Overrides:
compileToItem
in class ToIteratorCompiler
- Parameters:
compiler
- the compiler serviceexpression
- the expression to be compiled
- Throws:
CannotCompileException
