◆ clearItems()

template<typename SvcType , typename SvcPtrType >

static void Mantid::PythonInterface::DataServiceExporter< SvcType, SvcPtrType >::clearItems ( SvcType & self )

inlinestatic

Remove an item from the service.

Parameters

self	A reference to the calling object

◆ define()

template<typename SvcType , typename SvcPtrType >

static PythonType Mantid::PythonInterface::DataServiceExporter< SvcType, SvcPtrType >::define ( const char * pythonClassName )

inlinestatic

Define the necessary boost.python framework to expor the templated DataService type Note: This does not add the Instance method as that is on the SingletonHolder typedef.

To add this call the following methods on the object this function returns .def("Instance", &SingletonType::Instance, return_value_policy<reference_existing_object>(), "Return a reference to the ADS singleton") .staticmethod("Instance") where SingletonType is the typedef of the SingletonHolder, e.g. AnalysisDataService

Parameters

pythonClassName The name that the class should have in Python

Returns: The new class object that wraps the given C++ type

◆ extractCppValue()

template<typename SvcType , typename SvcPtrType >

static SvcPtrType Mantid::PythonInterface::DataServiceExporter< SvcType, SvcPtrType >::extractCppValue ( const boost::python::object & pyvalue )

inlinestatic

Extract a SvcPtrType C++ value from the Python object.

Parameters

pyvalue Value of the

Returns: The extracted value or thows an std::invalid_argument error

static boost::python::list Mantid::PythonInterface::DataServiceExporter< SvcType, SvcPtrType >::getObjectNamesAsList	(	SvcType const *const	self,
		const std::string &	contain
	)

inlinestatic

Return a Python list of object names from the ADS as this is far easier to work with than a set.

Parameters

self	:: A reference to the ADS object that called this method
contain	:: If provided, the function will return only names that contain this string

Returns: A python list created from the set of strings

static void Mantid::PythonInterface::DataServiceExporter< SvcType, SvcPtrType >::removeItem	(	SvcType &	self,
		const std::string &	name
	)

inlinestatic

Remove an item from the service.

Parameters

self	A reference to the calling object
name	The name of the item in the service to remove

template<typename SvcType , typename SvcPtrType >

static WeakPtr Mantid::PythonInterface::DataServiceExporter< SvcType, SvcPtrType >::retrieveOrKeyError	(	SvcType &	self,
		const std::string &	name
	)

inlinestatic

Retrieves a shared_ptr from the ADS and raises a Python KeyError if it does not exist.

Parameters

self	:: A pointer to the object calling this function. Allows it to act as a member function
name	:: The name of the object to retrieve

Returns: A shared_ptr to the named object. If the name does not exist it sets a KeyError error indicator.
