PoolManager

typedef SkipList_PoolManager bdlcc::SkipList_PoolUtil::PoolManager

Member Function Documentation

allocate()

static void * bdlcc::SkipList_PoolUtil::allocate ( PoolManager *  poolManager, int  level  )

static

Reserve sufficient space for a node at the specified level from the specified poolManager, and return the address of the reserved memory.

createPoolManager()

static PoolManager * bdlcc::SkipList_PoolUtil::createPoolManager ( int *  objectSizes, int  numLevels, bslma::Allocator *  basicAllocator  )

static

Create a new pooled node allocator that manages nodes up to the specified numLevels as described by the specified objectSizes. For i in [0, numLevels), a node at level i will have size objectSizes[i] bytes. Use the specified basicAllocator to supply memory. Return the address of the new allocator.

Note

Note that the behavior is undefined if basicAllocator is 0.

deallocate()

static void bdlcc::SkipList_PoolUtil::deallocate ( PoolManager *  poolManager, void *  address  )

static

Return the node at the specified address to the specified poolManager.

Precondition

The behavior is undefined if address was not allocated from poolManager.

deletePoolManager()

static void bdlcc::SkipList_PoolUtil::deletePoolManager ( bslma::Allocator *  basicAllocator, PoolManager *  poolManager  )

static

Destroy the specified poolManager which was allocated from the specified basicAllocator.

Precondition

The behavior is undefined if poolManager was not allocated from basicAllocator.
