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

Allocate()

virtual void* v8::ArrayBuffer::Allocator::Allocate ( size_t  length )

pure virtual

Allocate |length| bytes.

Return NULL if allocation is not successful. Memory should be initialized to zeroes.

Implemented in v8::MockArrayBufferAllocator, and v8::ShellArrayBufferAllocator.

Referenced by v8::internal::Runtime::SetupArrayBufferAllocatingData().

Here is the caller graph for this function:

AllocateUninitialized()

virtual void* v8::ArrayBuffer::Allocator::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 v8::MockArrayBufferAllocator, and v8::ShellArrayBufferAllocator.

Referenced by v8::internal::Runtime::SetupArrayBufferAllocatingData().

Here is the caller graph for this function:

Free()

virtual void v8::ArrayBuffer::Allocator::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 v8::MockArrayBufferAllocator, and v8::ShellArrayBufferAllocator.

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

Here is the caller graph for this function:
