Detailed Description

template<class t_TYPE, unsigned t_NUM_BITS>
class bdlb::NullableAllocatedValue_PointerBitsPair< t_TYPE, t_NUM_BITS >

This is a component-private class. Do not use.

This regular, value-semantic class provides a mechanism for storing a number of bit flags in the otherwise unused bits of a pointer to the template parameter class t_TYPE. The number of bits that can be stored is dependent upon the required alignment of the class t_TYPE.
