java.lang.Objectbsh.This
public final class This
'This' is the type of bsh scripted objects. A 'This' object is a bsh scripted object context. It holds a namespace reference and implements event listeners and various other interfaces. This holds a reference to the declaring interpreter for callbacks from outside of bsh.

public java.lang.Object invokeMethod(java.lang.String methodName, java.lang.Object[] args, Interpreter interpreter, CallStack callstack, bsh.SimpleNode callerInfo, boolean declaredOnly) throws EvalError
Note: If you use this method outside of the bsh package and wish to use variables with primitive values you will have to wrap them using bsh.Primitive. Consider using This getInterface() to make a true Java interface for invoking your scripted methods.
This method also implements the default object protocol of toString(), hashCode() and equals() and the invoke() meta-method handling as a last resort.
Note: The invoke() meta-method will not catch the Object protocol methods (toString(), hashCode()...). If you want to override them you have to script them directly.
callstack
- if callStack is null a new CallStack will be created and
initialized with this namespace.declaredOnly
- if true then only methods declared directly in the
namespace will be visible - no inherited or imported methods will
be visible.
EvalError
Primitive
public static void bind(This ths, NameSpace namespace, Interpreter declaringInterpreter)
This is a static utility method because it's used by a bsh command bind() and the interpreter doesn't currently allow access to direct methods of This objects (small hack)
