/**
|
|
* This interface provides access to the execution stack of a thread.
|
|
* It has several subclasses to distinguish between different kinds of
|
|
* stack frames: these currently include activations of Java methods
|
|
* or JavaScript functions.
|
|
* It is possible that synchronize blocks and try blocks deserve their own
|
|
* stack frames - to allow for later extensions a debugger should skip over
|
|
* stack frames it doesn't understand.
|
|
* Note that this appears very Java-specific. However, multiple threads and
|
|
* exceptions are relevant to JavaScript as well because of its
|
|
* interoperation with Java.
