public class This extends java.lang.Object implements java.io.Serializable, java.lang.Runnable'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.- See Also:

getInterface
public java.lang.Object getInterface(java.lang.Class clas)
Get dynamic proxy for interface, caching those it creates.
-
getInterface
public java.lang.Object getInterface(java.lang.Class[] ca)
Get dynamic proxy for interface, caching those it creates.

getNameSpace
public NameSpace getNameSpace()
-
toString
public java.lang.String toString()
- Overrides:
toStringin classjava.lang.Object

run
public void run()
- Specified by:

invokeMethod
public java.lang.Object invokeMethod(java.lang.String name, java.lang.Object[] args) throws EvalErrorInvoke 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 java.lang.Object invokeMethod(java.lang.String methodName, java.lang.Object[] args, Interpreter interpreter, CallStack callstack, bsh.SimpleNode callerInfo, boolean declaredOnly) throws EvalErrorInvoke 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() meta-method will not catch the Object protocol methods (toString(), hashCode()...). If you want to override them you have to script them directly.
-
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)
