API

Returns an array of callsite objects with the following methods:

• getThis: returns the value of this.

• getFunction: returns the current function.
• getFunctionName: returns the name of the current function, typically its name property. If a name property is not available an attempt will be made to try to infer a name from the function's context.
• getMethodName: returns the name of the property of this or one of its prototypes that holds the current function.
• getFileName: if this function was defined in a script returns the name of the script.
• getLineNumber: if this function was defined in a script returns the current line number.
• getColumnNumber: if this function was defined in a script returns the current column number
• getEvalOrigin: if this function was created using a call to eval returns a string representing the location where eval was called.
• isToplevel: is this a top-level invocation, that is, is this the global object?
• isEval: does this call take place in code defined by a call to eval?
• isNative: is this call in native V8 code?
• isConstructor: is this a constructor call?
