Class FnOrScript

java.lang.Object

org.apache.bsf.engines.javascript.FnOrScript

public class FnOrScript
extends java.lang.Object

This class represents a function or script, that is, a piece of a document that is provided to the JavaScript engine for evaluation, execution, or simply compilation. A FnOrScript represents a range of lines or characters in its document. For now, Rhino only supports ranges of lines, really, but the code for offsets is there anyway. Warning: Offsets have never been quite tested yet... A FnOrScript has compilation units. When Rhino compiles a function or a script, even in interpreted mode where the compilation is done to JavaScript bytecode, it calls back its debugger with different compilation units; see Debugger::handleCompilationDone method on the RhinoEngineDebugger class. A FnOrScript also keeps track of the known breakpoints in its range of lines or characters. It makes sure that they are propagated to the underlying Rhino engine (i.e. set) as well as unpropagated (i.e. unset).
