CAllocatorImpl

Implementation of IAllocator using Allocator. This adapts a statically-built allocator type to IAllocator that is directly usable by non-templated code.

Usually CAllocatorImpl is used indirectly by calling theAllocator.

Functions

alignedAllocate
void[] alignedAllocate(size_t s, uint a)

If impl.alignedAllocate exists, calls it and returns the result. Otherwise, always returns null.

alignedReallocate
bool alignedReallocate(ref void[] b, size_t s, uint a)

Forwards to impl.alignedReallocate if defined, false otherwise.

allocate
void[] allocate(size_t s, TypeInfo ti = null)

Returns impl.allocate(s).

allocateAll
void[] allocateAll()

Returns impl.allocateAll() if present, null otherwise.

deallocate
bool deallocate(void[] b)

If impl.deallocate is not defined, returns false. Otherwise it forwards the call.

deallocateAll
bool deallocateAll()

Calls impl.deallocateAll() and returns the result if defined, otherwise returns false.

empty
Ternary empty()

Forwards to impl.empty() if defined, otherwise returns Ternary.unknown.

expand
bool expand(ref void[] b, size_t s)

Returns impl.expand(b, s) if defined, false otherwise.

goodAllocSize
size_t goodAllocSize(size_t s)

Returns impl.goodAllocSize(s).

owns
Ternary owns(void[] b)

If Allocator implements owns, forwards to it. Otherwise, returns Ternary.unknown.

reallocate
bool reallocate(ref void[] b, size_t s)

Returns impl.reallocate(b, s).

Properties

alignment
uint alignment [@property getter]

Returns impl.alignment.

Inherited Members

From IAllocator

alignment
uint alignment [@property getter]

Returns the alignment offered.

goodAllocSize
size_t goodAllocSize(size_t s)

Returns the good allocation size that guarantees zero internal fragmentation.

allocate
void[] allocate(size_t, TypeInfo ti = null)

Allocates n bytes of memory.

alignedAllocate
void[] alignedAllocate(size_t n, uint a)

Allocates n bytes of memory with specified alignment a. Implementations that do not support this primitive should always return null.

allocateAll
void[] allocateAll()

Allocates and returns all memory available to this allocator. Implementations that do not support this primitive should always return null.

expand
bool expand(ref void[], size_t)

Expands a memory block in place and returns true if successful. Implementations that don't support this primitive should always return false.

reallocate
bool reallocate(ref void[], size_t)

Reallocates a memory block.

alignedReallocate
bool alignedReallocate(ref void[] b, size_t size, uint alignment)

Reallocates a memory block with specified alignment.

owns
Ternary owns(void[] b)

Returns Ternary.yes if the allocator owns b, Ternary.no if the allocator doesn't own b, and Ternary.unknown if ownership cannot be determined. Implementations that don't support this primitive should always return Ternary.unknown.

resolveInternalPointer
Ternary resolveInternalPointer(const void* p, ref void[] result)

Resolves an internal pointer to the full block allocated. Implementations that don't support this primitive should always return Ternary.unknown.

deallocate
bool deallocate(void[] b)

Deallocates a memory block. Implementations that don't support this primitive should always return false. A simple way to check that an allocator supports deallocation is to call deallocate(null).

deallocateAll
bool deallocateAll()

Deallocates all memory. Implementations that don't support this primitive should always return false.

empty
Ternary empty()

Returns Ternary.yes if no memory is currently allocated from this allocator, Ternary.no if some allocations are currently active, or Ternary.unknown if not supported.
