MethodCallDesc Class

The MethodCallDesc class provides information at run time about currently active method calls. It is the abstract class that defines the behavior of the MethodCallDesc objects that contain a reference to prior method call descriptions.

MethodCallDesc objects are used to represent the execution history of a Jade application thread and they are linked together in a stack. These objects are created only on demand, when it is necessary to take a "snapshot" of the current execution stack.

Use the currentStack method of the Process class to obtain the call stack for the current process. In addition, when an exception is raised, a MethodCallDesc object is attached to the Exception object, to represent the method and position where the exception was raised. ObjMethodCallDesc objects are created when the receiver is an instance of a class. PrimMethodCallDesc objects are created when the receiver is a primitive value.

For details about the properties and methods defined in the MethodCallDesc class, see "MethodCallDesc Properties" and "MethodCallDesc Methods", in the following subsections.
