Package io.deephaven.engine.util

Class PyCallableWrapperJpyImpl

java.lang.Object

io.deephaven.engine.util.PyCallableWrapperJpyImpl

All Implemented Interfaces:

PyCallableWrapper

public class PyCallableWrapperJpyImpl
extends Object
implements PyCallableWrapper

When given a pyObject that is a callable, we stick it inside the callable wrapper, which implements a call() varargs method, so that we can call it using __call__ without all of the JPy nastiness.
