Constructor & Destructor Documentation

◆ init() [1/3]

None CDPL.Util.BitSet.__init__ ( BitSet bs )

Initializes a copy of the BitSet instance bs.

Parameters

bs	The BitSet instance to copy.

◆ init() [2/3]

None CDPL.Util.BitSet.__init__	(	int	num_bits,
		int	value = `0`
	)

Initializes the BitSet instance.

Parameters

num_bits
value

◆ init() [3/3]

None CDPL.Util.BitSet.__init__ ( str bit_str )

Initializes the BitSet instance.

Parameters

bit_str

Member Function Documentation

◆ getObjectID()

int CDPL.Util.BitSet.getObjectID ( )

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

Different Python BitSet 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 BitSet 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.

◆ swap()

Parameters

bs
