Method Details

ensureLoadedForDebuggerEval

static void ensureLoadedForDebuggerEval()

runMeSomeCode

public static Object runMeSomeCode(Object enclosingInstance,
 ClassLoader cl,
 Object[] extSyms,
 String strText,
 String strClassContext,
 String strContextElementClass,
 int iSourcePosition)

Intended for use with a debugger to evaluate arbitrary expressions/programs in the context of a source position being debugged, usually at a breakpoint.

Parameters:

enclosingInstance - The instance of the object immediately enclosing the source position.

extSyms - An array of adjacent name/value pairs corresponding with the names and values of local symbols in scope.

strText - The text of the expression/program.

strClassContext - The name of the top-level class enclosing the the source position.

strContextElementClass - The name of the class immediately enclosing the source position (can be same as strClassContext).

iSourcePosition - The index of the source position within the containing file.

Returns:

The result of the expression or, in the case of a program, the return value of the program.
