Detailed Description

The Reconstruction class allows to build and apply a polynomial reconstructions.

Definition at line 307 of file reconstruction.hpp.

Constructor & Destructor Documentation

◆ Reconstruction()

bitpit::Reconstruction::Reconstruction	(	uint8_t	degree,
		uint8_t	dimensions )

Default constructor.

Parameters

degree	is the degree of the polynomial
dimensions	is the number of space dimensions

Definition at line 3620 of file reconstruction.cpp.

Member Function Documentation

◆ assemble()

void bitpit::Reconstruction::assemble ( )

Computes the weights to be used in order to calculate the coefficients of the polynomial. The coefficients are such that the conditions decoded in equations are enforced.

Definition at line 3673 of file reconstruction.cpp.

◆ clear()

void bitpit::Reconstruction::clear ( bool release = true )

Clear the reconstruction.

Parameters

release if true, the memory hold by the reconstruction will be released, otherwise the reconstruction will be cleared but its memory will not be released

Definition at line 3659 of file reconstruction.cpp.

◆ getCoefficientCount()

uint16_t bitpit::ReconstructionAssembler::getCoefficientCount ( ) const

Get the number of coefficients of the reconstruction polynomial.

Returns: The number of coefficients of the reconstruction polynomial.

Definition at line 264 of file reconstruction.cpp.

◆ getDegree()

uint8_t bitpit::ReconstructionAssembler::getDegree ( ) const

Get the degree of the polynomial.

Returns: The degree of the polynomial.

Definition at line 261 of file reconstruction.cpp.

◆ getDimensions()

uint8_t bitpit::ReconstructionAssembler::getDimensions ( ) const

Get the number of space dimensions.

Returns: The number of space dimensions.

Definition at line 262 of file reconstruction.cpp.

◆ initialize()

void bitpit::Reconstruction::initialize	(	uint8_t	degree,
		uint8_t	dimensions,
		bool	release = true )

Initialize the reconstruction.

Parameters

degree	is the degree of the polynomial
dimensions	is the number of space dimensions
release	if true, possible unneeded memory hold by the reconstruction will be released, otherwise the reconstruction will be initialized but possible unneeded memory will not be released

Definition at line 3647 of file reconstruction.cpp.

◆ swap()

void bitpit::Reconstruction::swap ( Reconstruction & other )

noexcept

Exchanges the content of the reconstruction by the content the specified other reconstruction.

Parameters

other is another reconstruction whose content is swapped with that of this reconstruction

Definition at line 3632 of file reconstruction.cpp.
