Detailed Description

template<typename Return>
class TfPyCall< Return >

Provide a way to call a Python callable.

Usage is as follows:

return TfPyCall<RetType>(callable)(arg1, arg2, ... argN);

Generally speaking, TfPyCall instances may be copied, assigned, destroyed, and invoked without the client holding the GIL. However, if the Return template parameter is a boost::python::object (or a derived class, such as list or tuple) then the client must hold the GIL in order to invoke the call operator.

TfPyCall()

TfPyCall ( TfPyObjWrapper const &  c )

inlineexplicit

Construct with callable c.

Constructing with a boost::python::object works, since those implicitly convert to TfPyObjWrapper, however in that case the GIL must be held by the caller.
