Constructor & Destructor Documentation

__init__() [1/8]

None CDPL.Math.LVector.__init__

(

LVector

v

)

Move-constructs a vector from v (v is left in a valid empty state).

Parameters

v	The vector to move from.

__init__() [2/8]

		int	v
	)

Constructs a vector of size n with every element initialized to v.

Parameters

n	The desired vector size.
v	The element value used to initialize every entry.

Member Function Documentation

resize()

None CDPL.Math.LVector.resize	(	int	n,
		int	v = 0
	)

Resizes the vector to n elements.

Parameters

n	The new element count.
v	The fill value for newly added elements.

clear()

None CDPL.Math.LVector.clear

(

int

v = 0

)

Sets every element of the vector to the value v.

Parameters

v	The fill value.

getObjectID()

int CDPL.Math.LVector.getObjectID

(

)

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

Different Python LVector 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 LVector 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.
