java.lang.Throwable

java.lang.Exception

bsh.EvalError

bsh.TargetError

All Implemented Interfaces:

java.io.Serializable

public final class TargetError
extends EvalError

TargetError is an EvalError that wraps an exception thrown by the script (or by code called from the script). TargetErrors indicate exceptions which can be caught within the script itself, whereas a general EvalError indicates that the script cannot be evaluated further for some reason. If the exception is caught within the script it is automatically unwrapped, so the code looks like normal Java code. If the TargetError is thrown from the eval() or interpreter.eval() method it may be caught and unwrapped to determine what exception was thrown.

printStackTrace

public void printStackTrace(boolean debug,

inNativeCode

public boolean inNativeCode()

Return true if the TargetError was generated from native code. e.g. if the script called into a compiled java class which threw the excpetion. We distinguish so that we can print the stack trace for the native code case... the stack trace would not be useful if the exception was generated by the script. e.g. if the script explicitly threw an exception... (the stack trace would simply point to the bsh internals which generated the exception).
