public void captureStackInfo(RhinoException ex)

Capture stack information from the given exception.

Parameters:

ex - an exception thrown during execution

public Object compile(CompilerEnvirons compilerEnv,
                      ScriptOrFnNode tree,
                      String encodedSource,
                      boolean returnFunction)

Compile the script or function from intermediate representation tree into an executable form.

Parameters:

compilerEnv - Compiler environment

tree - intermediate representation

encodedSource - encoding of the source code for decompilation

returnFunction - if true, compiling a function

Returns:

an opaque object that can be passed to either createFunctionObject or createScriptObject, depending on the value of returnFunction

public Function createFunctionObject(Context cx,
                                     Scriptable scope,
                                     Object bytecode,
                                     Object staticSecurityDomain)

Create a function object.

Parameters:

cx - Current context

scope - scope of the function

bytecode - opaque object returned by compile

staticSecurityDomain - security domain

Returns:

Function object that can be called

public Script createScriptObject(Object bytecode,
                                 Object staticSecurityDomain)

Create a script object.

Parameters:

bytecode - opaque object returned by compile

staticSecurityDomain - security domain

Returns:

Script object that can be evaluated

public String getPatchedStack(RhinoException ex,
                              String nativeStackTrace)

Given a native stack trace, patch it with script-specific source and line information

Parameters:

ex - exception

nativeStackTrace - the native stack trace

Returns:

patched stack trace

public List getScriptStack(RhinoException ex)

Get the script stack for the given exception

Parameters:

ex - exception from execution

Returns:

list of strings for the stack trace

public String getSourcePositionFromStack(Context cx,
                                         int[] linep)

Get the source position information by examining the stack.

Parameters:

cx - Context

linep - Array object of length >= 1; getSourcePositionFromStack will assign the line number to linep[0].

Returns:

the name of the file or other source container

public void setEvalScriptFlag(Script script)

Mark the given script to indicate it was created by a call to eval() or to a Function constructor.

Parameters:

script - script to mark as from eval
