Constructor & Destructor Documentation

__init__() [1/2]

None CDPL.Math.DZeroMatrix.__init__

(

DZeroMatrix

m

)

Initializes a copy of the DZeroMatrix instance m.

Parameters

m	The DZeroMatrix instance to copy.

__init__() [2/2]

None CDPL.Math.DZeroMatrix.__init__	(	int	m,
		int	n
	)

Initializes the DZeroMatrix instance.

Parameters

m
n

Member Function Documentation

resize()

None CDPL.Math.DZeroMatrix.resize	(	int	m,
		int	n
	)

Parameters

m
n

getObjectID()

int CDPL.Math.DZeroMatrix.getObjectID

(

)

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

Different Python DZeroMatrix 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 DZeroMatrix 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.
