CreatePyFunc()

static PyObject * Wasp::MyPython::CreatePyFunc ( string  moduleName, string  funcName, string  script  )

static

Create a python function object from a script

This method create a python function, named by funcName, from the Python script script. The script script must contain a python function definition for a function named by funcName. The function will be defined in the module named by moduleName. This module must already exist in the python environment.

Parameters

[in]	moduleName	Name of module in which to define the function.
[in]	name	of function defined in the script script
[in]	script	A string containing a valid python script

Return values

pFunc

A new PyObject reference to the defined function, or NULL if any Python API calls fail

Initialize()

int Wasp::MyPython::Initialize

(

)

Initialize the Python interpreter

Checks value of VAPOR_PYHONHOME environment variable. If set, passes it's value to Py_SetPythonHome(). Otherwise uses GetAppsPath() to find the location of Python .so's and calls Py_SetPythonHome() with path returned by GetAppsPath(). Finally calls Py_Initialize()

Instance()

static MyPython * Wasp::MyPython::Instance ( )

static

PyErr()

string Wasp::MyPython::PyErr

(

)

Return python errors as a string

This method can be used to return errors generated by scripts launched by the python C API. For example, if a script run by PyRun_SimpleString fails and raises an exception this method will return the error string generated

PyOut()

string Wasp::MyPython::PyOut

(

)

Return stdout message as a string.
