Constructor & Destructor Documentation

__init__() [1/2]

None CDPL.Math.DZeroVector.__init__

(

DZeroVector

v

)

Initializes a copy of the DZeroVector instance v.

Parameters

v	The DZeroVector instance to copy.

__init__() [2/2]

None CDPL.Math.DZeroVector.__init__

(

int

n

)

Initializes the DZeroVector instance.

Parameters

n

Member Function Documentation

resize()

None CDPL.Math.DZeroVector.resize

(

int

n

)

Parameters

n

getObjectID()

int CDPL.Math.DZeroVector.getObjectID

(

)

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

Different Python DZeroVector 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 DZeroVector 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.
