Detailed Description

This class provides methods for making inquires to the data of a group control loading during construction.

Constructor & Destructor Documentation

FlatHashTable_GroupControl()

bdlc::FlatHashTable_GroupControl::FlatHashTable_GroupControl ( const bsl::uint8_t *  data )

inlineexplicit

Create a group control query object using the specified data. The bytes of data have no alignment requirement. The behavior is undefined unless data has at least k_SIZE bytes available.

Member Function Documentation

available()

bsl::uint32_t bdlc::FlatHashTable_GroupControl::available ( ) const

inline

Return a bit mask of the k_SIZE entries that are empty or erased. The bit at index i corresponds to the result for data[i].

inUse()

bsl::uint32_t bdlc::FlatHashTable_GroupControl::inUse ( ) const

inline

Return a bit mask of the k_SIZE entries that are in use (i.e., not empty or erased). The bit at index i corresponds to the result for data[i].

match()

bsl::uint32_t bdlc::FlatHashTable_GroupControl::match ( bsl::uint8_t  value ) const

inline

Return a bit mask of the k_SIZE entries that have the specified value. The bit at index i corresponds to the result for data[i]. The behavior is undefined unless 0 == (0x80 & value).

neverFull()

bool bdlc::FlatHashTable_GroupControl::neverFull ( ) const

inline

Return true if this group control was never full (i.e., has a value that is empty, but not erased).
