Member Function Documentation

allocate()

virtual void* roc::core::IPool::allocate ( )

pure virtual

Allocate memory for an object.

Returns

pointer to a maximum aligned uninitialized memory for a new object or NULL if memory can't be allocated.

Implemented in roc::core::SlabPool< T, EmbeddedCapacity >, roc::core::SlabPool< roc::core::Buffer< T > >, roc::core::SlabPool< roc::packet::Packet >, roc::core::SlabPool< Slot >, and roc::core::SlabPool< Node, PreallocatedNodes >.

deallocate()

virtual void roc::core::IPool::deallocate ( void *  memory )

pure virtual

Return memory to pool.

Implemented in roc::core::SlabPool< T, EmbeddedCapacity >, roc::core::SlabPool< roc::core::Buffer< T > >, roc::core::SlabPool< roc::packet::Packet >, roc::core::SlabPool< Slot >, and roc::core::SlabPool< Node, PreallocatedNodes >.

destroy_object()

template<class T >

void roc::core::IPool::destroy_object ( T &  object )

inline

Destroy object and deallocate its memory.

Definition at line 45 of file ipool.h.

object_size()

virtual size_t roc::core::IPool::object_size ( ) const

pure virtual

Get size of object allocated by pool.

Implemented in roc::core::SlabPool< T, EmbeddedCapacity >, roc::core::SlabPool< roc::core::Buffer< T > >, roc::core::SlabPool< roc::packet::Packet >, roc::core::SlabPool< Slot >, and roc::core::SlabPool< Node, PreallocatedNodes >.

reserve()

virtual ROC_ATTR_NODISCARD bool roc::core::IPool::reserve ( size_t  n_objects )

pure virtual

Reserve memory for given number of objects.

Returns

false if allocation failed.

Implemented in roc::core::SlabPool< T, EmbeddedCapacity >, roc::core::SlabPool< roc::core::Buffer< T > >, roc::core::SlabPool< roc::packet::Packet >, roc::core::SlabPool< Slot >, and roc::core::SlabPool< Node, PreallocatedNodes >.
