Detailed Description
Abstract algorithm, base element of OpenViBE processing objects
This class should be derived by any plugin that is related to data processing. It basically has a parameterable interface contained in the IAlgorithmContext object. This interface stores several typed parameters which can be modified either by outside world in order to provide input paramters to this algorithm or by this algorithm itself in order to produce output parameters.

Member Function Documentation
virtual OpenViBE::boolean initialize | ( | OpenViBE::Kernel::IAlgorithmContext & | rAlgorithmContext | ) | [inline, virtual] |
Initializes this algorithm.
- Parameters:
-
rAlgorithmContext [in] : the execution context for this algorithm
- Returns:
- true in case of success.
- false in case of error.
virtual OpenViBE::boolean uninitialize | ( | OpenViBE::Kernel::IAlgorithmContext & | rAlgorithmContext | ) | [inline, virtual] |
Unitializes this algorithm.
- Parameters:
-
rAlgorithmContext [in] : the extecution context for this algorithm
- Returns:
- true in case of success.
- false in case of error.
virtual OpenViBE::boolean process | ( | OpenViBE::Kernel::IAlgorithmContext & | rAlgorithmContext | ) | [pure virtual] |
Effectively executes this algorithm.
- Parameters:
-
rAlgorithmContext [in] : the extecution context for this algorithm
- Returns:
- true in case of success.
- false in case of error.
When called, this function should get its "input" parameters, do stuffs with them and finally produce "ouput" parameters.
