JS_DecompileFunction 编辑

Generates the complete source code of a function declaration from a compiled function.

Syntax

JSString *
JS_DecompileFunction(JSContext *cx, JS::Handle<JSFunction*> fun);

Description

JS_DecompileFunction generates the complete source code of a function declaration from a function's compiled form, fun.

If successful, JS_DecompileFunction returns a string containing the text of the function. Otherwise, it returns NULL.

If you decompile a function that does not make a native C call, then the text created by JS_DecompileFunction is a complete function declaration suitable for re-parsing. If you decompile a function that makes a native C call, the body of the function contains the text "native code'" and cannot be re-parsed.
