Member Function Documentation

◆ AdoptSharedValueConveyor()

bool v8::Serializer::AdoptSharedValueConveyor	(	Isolate *	isolate,
		SharedValueConveyor &&	conveyor )

inlineoverrideprotectedvirtual

Called when the first shared value is serialized. All subsequent shared values will use the same conveyor.

The embedder must ensure the lifetime of the conveyor matches the lifetime of the serialized data.

If the embedder supports serializing shared values, this method should return true. Otherwise the embedder should throw an exception and return false.

This method is called at most once per serializer.

Reimplemented from v8::ValueSerializer::Delegate.

Here is the call graph for this function:

◆ FreeBufferMemory()

void v8::Serializer::FreeBufferMemory ( void * buffer )

inlineoverrideprotectedvirtual

Frees a buffer allocated with |ReallocateBufferMemory|.

The default implementation uses the stdlib's free() function.

Reimplemented from v8::ValueSerializer::Delegate.

Definition at line 6247 of file d8.cc.

◆ GetSharedArrayBufferId()

Maybe< uint32_t > v8::Serializer::GetSharedArrayBufferId	(	Isolate *	isolate,
		Local< SharedArrayBuffer >	shared_array_buffer )

inlineoverrideprotectedvirtual

Called when the ValueSerializer is going to serialize a SharedArrayBuffer object. The embedder must return an ID for the object, using the same ID if this SharedArrayBuffer has already been serialized in this buffer. When deserializing, this ID will be passed to ValueDeserializer::GetSharedArrayBufferFromId as |clone_id|.

If the object cannot be serialized, an exception should be thrown and Nothing<uint32_t>() returned.

Reimplemented from v8::ValueSerializer::Delegate.

Definition at line 6202 of file d8.cc.

◆ GetWasmModuleTransferId()

Maybe< uint32_t > v8::Serializer::GetWasmModuleTransferId	(	Isolate *	isolate,
		Local< WasmModuleObject >	module )

inlineoverrideprotectedvirtual

Reimplemented from v8::ValueSerializer::Delegate.

◆ PrepareTransfer()

Maybe< bool > v8::Serializer::PrepareTransfer	(	Local< Context >	context,

Definition at line 6256 of file d8.cc.

Here is the call graph for this function:

◆ ReallocateBufferMemory()

void * v8::Serializer::ReallocateBufferMemory	(	void *	old_buffer,
		size_t	size,
		size_t *	actual_size )

inlineoverrideprotectedvirtual

Allocates memory for the buffer of at least the size provided. The actual size (which may be greater or equal) is written to |actual_size|. If no buffer has been allocated yet, nullptr will be provided.

If the memory cannot be allocated, nullptr should be returned. |actual_size| will be ignored. It is assumed that |old_buffer| is still valid in this case and has not been modified.

The default implementation uses the stdlib's realloc() function.

Reimplemented from v8::ValueSerializer::Delegate.

Definition at line 6233 of file d8.cc.

◆ Release()

std::unique_ptr< SerializationData > v8::Serializer::Release ( )

inline

Definition at line 6188 of file d8.cc.

Here is the caller graph for this function:

◆ ThrowDataCloneError()

void v8::Serializer::ThrowDataCloneError ( Local< String > message )

inlineoverrideprotectedvirtual

Handles the case where a DataCloneError would be thrown in the structured clone spec. Other V8 embedders may throw some other appropriate exception type.

Implements v8::ValueSerializer::Delegate.

Definition at line 6198 of file d8.cc.
