Detailed Description

Allocator that V8 uses to allocate |ArrayBuffer|'s memory. The allocator is a global V8 setting. It should be set with V8::SetArrayBufferAllocator prior to creation of a first ArrayBuffer.

This API is experimental and may change significantly.

Member Function Documentation

virtual void* Allocate ( size_t  length )

pure virtual

Allocate |length| bytes. Return NULL if allocation is not successful. Memory should be initialized to zeroes.

Implemented in MockArrayBufferAllocator, and ShellArrayBufferAllocator.

Referenced by Runtime::SetupArrayBufferAllocatingData().

virtual void* AllocateUninitialized ( size_t  length )

pure virtual

Allocate |length| bytes. Return NULL if allocation is not successful. Memory does not have to be initialized.

Implemented in MockArrayBufferAllocator, and ShellArrayBufferAllocator.

Referenced by Runtime::SetupArrayBufferAllocatingData().

virtual void Free ( void *  data, size_t  length  )

pure virtual

Free the memory block of size |length|, pointed to by |data|. That memory is guaranteed to be previously allocated by |Allocate|.

Implemented in MockArrayBufferAllocator, and ShellArrayBufferAllocator.

Referenced by Runtime::FreeArrayBuffer(), FreeBufferExtension::FreeBuffer(), and v8::internal::RUNTIME_FUNCTION().
