Detailed Description

An allocator interface for managing memory explicitly.

Implementations of this interface must be thread-safe as V8 will invoke these methods concurrently from multiple threads.

Member Function Documentation

Allocate()

virtual void * v8::Allocator::Allocate ( size_t  size )

pure virtual

Allocates zero-initialized memory.

Parameters

size	The number of bytes to allocate.

Returns

Pointer to the allocated memory or nullptr on failure.

AllocateUninitialized()

virtual void * v8::Allocator::AllocateUninitialized ( size_t  size )

pure virtual

Allocates uninitialized memory.

Parameters

size	The number of bytes to allocate.

Returns

Pointer to the allocated memory or nullptr on failure.

AllocateUninitializedOrCrash()

virtual void * v8::Allocator::AllocateUninitializedOrCrash ( size_t  size )

pure virtual

Allocates uninitialized memory.

Parameters

size	The number of bytes to allocate.

Returns

Pointer to the allocated memory. Crashes on failure (e.g. OOM). This is intended for critical allocations where failure means the process cannot continue.

Free()

virtual void v8::Allocator::Free ( void *  ptr )

pure virtual

Frees memory that was acquired with one of the allocation methods.

Parameters

ptr	Pointer to the memory to free. If ptr is nullptr, no operation is performed.
