Detailed Description

Stores mappings between point-entry equations and block-entry equations. This class, once initialized, can answer queries such as:
Given a point-equation, return the corresponding block-equation.
or, Given a block-equation, return the corresponding size (number of point-equations contained in the block).

Member Function Documentation

void snl_fei::PointBlockMap::setPtEqualBlk ( )

Indicate to this object that point-equations are equal to block-equations which means that all block-equation sizes are 1 and all mappings are trivial. This will cause the internal mapping objects to be emptied, to save memory, and all lookup queries will be instant.

Definition at line 36 of file snl_fei_PointBlockMap.cpp.

bool snl_fei::PointBlockMap::ptEqualBlk ( )

inline

query whether block-size == 1, i.e., "point-equals-block"

Definition at line 40 of file snl_fei_PointBlockMap.hpp.

int snl_fei::PointBlockMap::setEqn	(	int	ptEqn,
		int	blkEqn
	)

Establish the mapping blkEqn => ptEqn. I.e., insert ptEqn and blkEqn into internal structures, and establish a correspondence between them. This function returns an error if 'setPtEqualBlk' has been called and ptEqn != blkEqn.

Definition at line 42 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::setEqn	(	int	ptEqn,
		int	blkEqn,
		int	blkSize
	)

Establish the mapping blkEqn => ptEqn. I.e., insert ptEqn and blkEqn into internal structures, and establish a correspondence between them, also setting the associated block-size. This function returns an error if 'setPtEqualBlk' has been called and ptEqn != blkEqn.

Definition at line 48 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::setBlkEqnSize	(	int	blkEqn,
		int	size
	)

Store the specified size corresponding to the specified block-equation.

Note that blkEqn must already have appeared in a call to 'setEqn', in order to establish it in a mapping. Otherwise, an error (-1) is returned.

Definition at line 85 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::getBlkEqnSize ( int blkEqn )

Given a blkEqn, return the corresponding size.

Definition at line 106 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::getMaxBlkEqnSize ( )

inline

Query the maximum block-equation size

Definition at line 68 of file snl_fei_PointBlockMap.hpp.

void snl_fei::PointBlockMap::setMaxBlkEqnSize ( int sz )

inline

Set the maximum block-equation size

Definition at line 72 of file snl_fei_PointBlockMap.hpp.

int snl_fei::PointBlockMap::eqnToBlkEqn ( int eqn ) const

Given a point-equation, return the corresponding block-equation. If eqn does not correspond to a block-equation, then -1 is returned. A return-value of -1 always indicates a not-found or not-valid error.

Definition at line 121 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::blkEqnToPtEqn ( int blkEqn ) const

Given a block-equation, return the corresponding point-equation (the first of the point-equations that correspond to that block-equation). If blkEqn does not correspond to a point-equation, then -1 is returned.

Definition at line 133 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::getBlkEqnInfo	(	int	blkEqn,
		int &	ptEqn,
		int &	blkSize
	)

Given a block-equation, query for the corresponding point-equation (the first of the corresponding point-equations) and the block-size, or number of corresponding point-equations.

Returns: -1 if block-equation not found, 0 if no error

Definition at line 148 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::getPtEqnInfo	(	int	ptEqn,
		int &	blkEqn,
		int &	blkOffset
	)

Given a point-equation, query for the corresponding block-equation and the offset of this point-equation into the block-equation.

Returns: -1 if point-equation not found, 0 if no error

Definition at line 169 of file snl_fei_PointBlockMap.cpp.

int snl_fei::PointBlockMap::getBlkEqnOffset	(	int	blkEqn,
		int	ptEqn
	)

Given a blkEqn/ptEqn pair, return the offset of the ptEqn into the blkEqn. Example: if blkEqn 23 corresponds to ptEqn 69, and the arguments to this function are blkEqn==23 and ptEqn==71, then the return value is 2, which is the offset of ptEqn==71 into blkEqn==23.

Definition at line 198 of file snl_fei_PointBlockMap.cpp.

bool snl_fei::PointBlockMap::isExactlyBlkEqn ( int ptEqn )

Query whether specified point-equation is the first equation within a block-equation

Definition at line 210 of file snl_fei_PointBlockMap.cpp.

std::map<int,int>* snl_fei::PointBlockMap::getPtEqns ( )

inline

Return database of point-equations

Definition at line 115 of file snl_fei_PointBlockMap.hpp.

std::map<int,std::pair<int,int> >* snl_fei::PointBlockMap::getBlkEqns ( )

inline

Return database of block-equations
