public void compileToItem(CompilerService compiler,
Expression expression)
throws CannotCompileException
ExpressionCompiler
compileToItem in class ExpressionCompilercompiler - the compiler serviceexpression - the expression to be compiled
CannotCompileException
public void compileToPrimitive(CompilerService compiler,
Expression expression,
Class requiredClass,
OnEmpty onEmpty)
throws CannotCompileException
compileToPrimitive in class ExpressionCompilercompiler - the compiler serviceexpression - the expression to be compiledrequiredClass - the class of the Java value that is to be left on the stack if the generated code
exits normally. This must be one of Integer.TYPE, Double.TYPE, Float.TYPE, BigDecimal.class, CharSequence.class.onEmpty - action to be performed if the value of the expression is an empty sequence
CannotCompileException
public void compileToIterator(CompilerService compiler,
Expression expression)
throws CannotCompileException

Precondition: none.
Postcondition: at execution time, the stack contains a SequenceIterator representing the result of the expression
