Member Function Documentation

clear()

None CDPL.Math.Vector7D.clear

(

float

v = 0.0

)

Sets every element of the vector to the value v.

Parameters

v	The fill value.

getObjectID()

int CDPL.Math.Vector7D.getObjectID

(

)

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

Different Python Vector7D 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 Vector7D 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.
