ENUM_MATRIX_TYPE matrixType
 matrixType tracks the type of elements contained in this MatrixNode, which may be useful in solver selection For an enumeration of the possible types see OSParameters.h
 
ENUM_MATRIX_CONSTRUCTOR_TYPE nType
 nType is a unique integer assigned to each type of matrix node (see OSParameters.h)
 
unsigned int inumberOfChildren
 inumberOfChildren is the number of MatrixNode child elements For the matrix types (OSMatrix and MatrixBlock) this number is not fixed and is temporarily set to 0
 
MatrixNode ** m_mChildren
 m_mChildren holds all the children, that is, nodes used in the definition or construction of the current node.

Member Function Documentation

◆ getNodeType()

ENUM_MATRIX_CONSTRUCTOR_TYPE MatrixTransformation::getNodeType ( )
virtual
Returns
the value of nType

Reimplemented from MatrixNode.

Definition at line 4051 of file OSMatrix.cpp.

◆ getNodeName()

std::string MatrixTransformation::getNodeName ( )
virtual
Returns
the name of the operator

Implements MatrixNode.

Definition at line 4056 of file OSMatrix.cpp.

◆ getMatrixType()

ENUM_MATRIX_TYPE MatrixTransformation::getMatrixType ( )
virtual
Returns
the type of the matrix elements

Implements MatrixNode.

Definition at line 4061 of file OSMatrix.cpp.

◆ getMatrixNodeInXML()

std::string MatrixTransformation::getMatrixNodeInXML ( )
virtual

The following method writes a matrix node in OSgL format. it is used by OSgLWriter to write a <matrix> element.

Returns
the MatrixNode and its children as an OSgL string.

Implements MatrixNode.

Definition at line 4068 of file OSMatrix.cpp.

◆ alignsOnBlockBoundary()

bool MatrixTransformation::alignsOnBlockBoundary ( int firstRow,
int firstColumn,
int nRows,
int nCols )
virtual

Check whether a submatrix aligns with the block partition of a matrix or block or other constructor.

Parameters
firstRowgives the number of the first row in the submatrix (zero-based)
firstColumngives the number of the first column in the submatrix (zero-based)
nRowsgives the number of rows in the submatrix
nColumnsgives the number of columns in the submatrix
Returns
true if the submatrix aligns with the boundaries of a block

Implements MatrixNode.

Definition at line 4082 of file OSMatrix.cpp.

◆ cloneMatrixNode()

MatrixTransformation * MatrixTransformation::cloneMatrixNode ( )
virtual

The implementation of the virtual functions.

Returns
a pointer to a new MatrixNode of the proper type.

Implements MatrixNode.

Definition at line 4087 of file OSMatrix.cpp.

◆ IsEqual()

bool MatrixTransformation::IsEqual ( MatrixTransformation * that)

A function to check for the equality of two objects.

Definition at line 4094 of file OSMatrix.cpp.

◆ setRandom()

bool MatrixTransformation::setRandom ( double density,
bool conformant,
int iMin,
int iMax )

A function to make a random instance of this class.

Parameters
densitycorresponds to the probability that a particular child element is created
conformantif true enforces side constraints not enforceable in the schema (e.g., agreement of "numberOfXXX" attributes and <XXX> children)
iMinlowest index value (inclusive) that a variable reference in this matrix can take
iMaxgreatest index value (inclusive) that a variable reference in this matrix can take

◆ deepCopyFrom()

bool MatrixTransformation::deepCopyFrom ( MatrixTransformation * that)

A function to make a deep copy of an instance of this class.

Parameters
thatthe instance from which information is to be copied
Returns
whether the copy was created successfully
