own()

template<typename Type >

bool ripple::SlabAllocator< Type >::SlabBlock::own ( std::uint8_t const *  p ) const

noexcept

Determines whether the given pointer belongs to this allocator.

Definition at line 108 of file SlabAllocator.h.

allocate()

template<typename Type >

std::uint8_t * ripple::SlabAllocator< Type >::SlabBlock::allocate ( )

noexcept

Definition at line 114 of file SlabAllocator.h.

deallocate()

template<typename Type >

void ripple::SlabAllocator< Type >::SlabBlock::deallocate ( std::uint8_t *  ptr )

noexcept

Return an item to this allocator's freelist.

Parameters

ptr	The pointer to the chunk of memory being deallocated.

Note

This is a dangerous, private interface; the item being returned should belong to this allocator. Debug builds will check and assert if this is not the case. Release builds will not.
