Detailed Description

Abstract class for "cloneable" linear systems.

This class is needed in the case that matrix entry lookups are not possible concurrently (e.g. for hierarchization systems with Clenshaw-Curtis grids).

Constructor & Destructor Documentation

◆ CloneableSLE()

Member Function Documentation

◆ clone()

virtual void sgpp::optimization::CloneableSLE::clone ( std::unique_ptr< CloneableSLE > & clone ) const

pure virtual

Pure virtual method for cloning the linear system.

It should generate a pointer to the cloned object and it's used for parallel computations (e.g. the getMatrixEntry() method might not be thread-safe).

Parameters

[out] clone pointer to cloned object

Implemented in sgpp::optimization::HierarchisationSLE, and sgpp::optimization::FullSLE.

Referenced by ~CloneableSLE().

◆ isCloneable()

bool sgpp::optimization::CloneableSLE::isCloneable ( ) const

inlineoverridevirtual

Returns: whether this system derives from CloneableSLE or not (true)

Reimplemented from sgpp::optimization::SLE.
