		int	i
	)

Initializes the ConstULMatrixRow instance.

Parameters

e
i

Member Function Documentation

◆ getIndex()

int CDPL.Math.ConstULMatrixRow.getIndex ( )

Returns the row index this proxy refers to within the wrapped matrix.

Returns: The zero-based row index.

◆ getObjectID()

int CDPL.Math.ConstULMatrixRow.getObjectID ( )

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python ConstULMatrixRow instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two ConstULMatrixRow instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns: The numeric ID of the internally referenced C++ class instance.

◆ isEmpty()

bool CDPL.Math.ConstULMatrixRow.isEmpty ( )

Tells whether the row is empty (the wrapped matrix has zero columns).

Returns: True if the wrapped matrix has zero columns, and False otherwise.

◆ getSize()

int CDPL.Math.ConstULMatrixRow.getSize ( )

Returns the size of the row (number of columns of the wrapped matrix).

Returns: The number of columns.

◆ getData()

ConstULMatrixExpression CDPL.Math.ConstULMatrixRow.getData ( )

Returns a reference to the wrapped matrix (via its stored closure).

Returns: A reference to the wrapped matrix closure.

◆ eq() [1/2]

bool CDPL.Math.ConstULMatrixRow.__eq__ ( ConstULMatrixRow r )

Returns the result of the comparison operation self == r.

Parameters

r	The `ConstULMatrixRow` instance to be compared with.

Returns: The result of the comparison operation.

◆ eq() [2/2]

bool CDPL.Math.ConstULMatrixRow.__eq__ ( ConstULVectorExpression e )

Returns the result of the comparison operation self == e.

Parameters

e	The `ConstULVectorExpression` instance to be compared with.

Returns: The result of the comparison operation.

◆ ne() [1/2]

bool CDPL.Math.ConstULMatrixRow.__ne__ ( ConstULMatrixRow r )

Returns the result of the comparison operation self != r.

Parameters

r	The `ConstULMatrixRow` instance to be compared with.

Returns: The result of the comparison operation.

◆ ne() [2/2]

bool CDPL.Math.ConstULMatrixRow.__ne__ ( ConstULVectorExpression e )

Returns the result of the comparison operation self != e.

Parameters

e	The `ConstULVectorExpression` instance to be compared with.

Returns: The result of the comparison operation.

◆ call()

int CDPL.Math.ConstULMatrixRow.__call__ ( int i )

Returns a reference to the element at column i of the row.

Parameters

i	The zero-based column index.

Returns: A reference to the underlying element m(index, i).

◆ getitem()

int CDPL.Math.ConstULMatrixRow.__getitem__ ( int i )

Returns a reference to the element at column i of the row.

Parameters

i	The zero-based column index.

Returns: A reference to the underlying element.

◆ len()

int CDPL.Math.ConstULMatrixRow.__len__ ( )

Returns the size of the row (number of columns of the wrapped matrix).

Returns: The number of columns.

◆ str()

str CDPL.Math.ConstULMatrixRow.__str__ ( )

Returns a string representation of the ConstULMatrixRow instance.

Returns: The generated string representation.

◆ add()

ConstULVectorExpression CDPL.Math.ConstULMatrixRow.__add__ ( ConstULVectorExpression e )

Returns the result of the addition operation self + e.

Parameters

e	Specifies the second addend.

Returns: A ConstULVectorExpression instance holding the result of the addition.

◆ sub()

ConstULVectorExpression CDPL.Math.ConstULMatrixRow.__sub__ ( ConstULVectorExpression e )

Returns the result of the subtraction operation self - e.

Parameters

e	Specifies the subtrahend.

Returns: A ConstULMatrixRow instance holding the result of the subtraction.

◆ mul() [1/2]

ConstULVectorExpression CDPL.Math.ConstULMatrixRow.__mul__ ( int t )

Returns the result of the multiplication operation self * t.
