Detailed Description

Selects oneVPL implementation according to the specified properties.

This object iterates over the available implementations and selects an appropriate one based on the list of properties. API user can create an instance of that class. If user wants to change the implementation selection behaviour they need to subslass and implement operator ().

Member Function Documentation

operator()()

virtual bool oneapi::vpl::implemetation_selector::operator() ( std::shared_ptr< base_implementation_capabilities >  caps ) const

protectedpure virtual

This operator is applyed to any found oneVPL implementation. If operator returns true, a session based on found implementation is created. Otherwise, search is continued.

Parameters

caps	Pointer to the session capabilities information in the requested format.

Returns

True, if implementation is good to go, false if search must continue.

Implemented in oneapi::vpl::default_selector.

session()

auto oneapi::vpl::implemetation_selector::session ( ) const

inline

Creates session which has the requested properties. Session class object calls this method at the ctor and takes care on deletion of loader and session handles.

Returns

Pair of loader handle and associated session handle.
