'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.
static void | bind(This ths, NameSpace namespace, Interpreter declaringInterpreter) - Bind a This reference to a parent's namespace with the specified
declaring interpreter.

Object | getInterface(Class clas) - Get a version of this scripted object implementing the specified
interface.
|
Object | getInterface(Class[] ca) - Get a version of this scripted object implementing the specified
interfaces.

NameSpace | getNameSpace()
|
Object | invokeMethod(String name, Object[] args) - Invoke specified method as from outside java code, using the
declaring interpreter and current namespace.
|
Object | invokeMethod(String methodName, Object[] args, Interpreter interpreter, CallStack callstack, bsh.SimpleNode callerInfo) - Invoke a method in this namespace with the specified args,
interpreter reference, callstack, and caller info.

bind
public static void bind(This ths,
NameSpace namespace,
Interpreter declaringInterpreter)
Bind a This reference to a parent's namespace with the specified
declaring interpreter. Also re-init the callstack. It's necessary
to bind a This reference before it can be used after deserialization.
This is used by the bsh load() command.
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)
getInterface
public Object getInterface(Class clas)
throws UtilEvalError
Get a version of this scripted object implementing the specified
interface.
getInterface
public Object getInterface(Class[] ca)
throws UtilEvalError
Get a version of this scripted object implementing the specified
interfaces.
invokeMethod
public Object invokeMethod(String name,
Object[] args)
throws EvalError
Invoke specified method as from outside java code, using the
declaring interpreter and current namespace.
The call stack will indicate that the method is being invoked from
outside of bsh in native java code.
Note: you must still wrap/unwrap args/return values using
Primitive/Primitive.unwrap() for use outside of BeanShell.
invokeMethod
public Object invokeMethod(String methodName,
Object[] args,
Interpreter interpreter,
CallStack callstack,
bsh.SimpleNode callerInfo)
throws EvalError
Invoke a method in this namespace with the specified args,
interpreter reference, callstack, and caller info.
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() method will not catch the object method
(toString, ...). If you want to override them you have to script
them directly.
