Detailed Description

template<typename T>
class regina::BitManipulatorByType< T >

Contains implementation details for BitManipulator where we optimise according to the underlying data type.

End users should use the BitManipulator class, not this class.

Python: Only the end-user class BitManipulator<unsigned long> is available to Python users.

Template Parameters

T	an unsigned integral numeric type, which we treat as a sequence of `true` and/or `false` bits.

Member Function Documentation

template<typename T >

static T regina::BitManipulatorByType< T >::nextPermutation ( T x )

inlinestatic

Returns the next largest integer with the same number of true bits as x.

If x is the largest such integer (i.e., x is of the form 111...1000...0), then this routine returns 0.

Parameters

x	the integer of type T to examine.

Returns: the next largrst integer with the same number of true bits, or 0 if this is the largest such integer.

template<typename T >

constexpr bool regina::BitManipulatorByType< T >::specialised = false

staticconstexpr

Indicates whether this class is a template specialisation of BitManipulatorByType with extra optimisations.

This compile-time constant is set to false for the generic implementation of BitManipulatorByType, and true for all specialisations.
