Member Function Documentation

GetWireFormatVersion()

uint32_t v8::ValueDeserializer::GetWireFormatVersion

(

)

const

Reads the underlying wire format version. Likely mostly to be useful to legacy code reading old wire format versions. Must be called after ReadHeader.

operator=()

void v8::ValueDeserializer::operator= ( const ValueDeserializer &  )

delete

ReadDouble()

bool v8::ValueDeserializer::ReadDouble

(

double *

value

)

ReadHeader()

Maybe< bool > v8::ValueDeserializer::ReadHeader

(

Local< Context >

context

)

Reads and validates a header (including the format version). May, for example, reject an invalid or unsupported wire format.

ReadRawBytes()

bool v8::ValueDeserializer::ReadRawBytes	(	size_t	length,
		const void **	data
	)

ReadUint32()

bool v8::ValueDeserializer::ReadUint32

(

uint32_t *

value

)

Reads raw data in various common formats to the buffer. Note that integer types are read in base-128 varint format, not with a binary copy. For use during an override of Delegate::ReadHostObject.

ReadUint64()

bool v8::ValueDeserializer::ReadUint64

(

uint64_t *

value

)

ReadValue()

MaybeLocal< Value > v8::ValueDeserializer::ReadValue

(

Local< Context >

context

)

Deserializes a JavaScript value from the buffer.

SetSupportsLegacyWireFormat()

void v8::ValueDeserializer::SetSupportsLegacyWireFormat

(

bool

supports_legacy_wire_format

)

Must be called before ReadHeader to enable support for reading the legacy wire format (i.e., which predates this being shipped).

Don't use this unless you need to read data written by previous versions of blink::ScriptValueSerializer.

TransferArrayBuffer()

void v8::ValueDeserializer::TransferArrayBuffer	(	uint32_t	transfer_id,
		Local< ArrayBuffer >	array_buffer
	)

Accepts the array buffer corresponding to the one passed previously to ValueSerializer::TransferArrayBuffer.

TransferSharedArrayBuffer()

void v8::ValueDeserializer::TransferSharedArrayBuffer	(	uint32_t	id,
		Local< SharedArrayBuffer >	shared_array_buffer
	)

Similar to TransferArrayBuffer, but for SharedArrayBuffer. The id is not necessarily in the same namespace as unshared ArrayBuffer objects.
