uint32_t 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.

V8_WARN_UNUSED_RESULT bool ReadDouble | ( | double * | value | ) |
V8_WARN_UNUSED_RESULT Maybe<bool> ReadHeader | ( | Local< Context > | context | ) |
Reads and validates a header (including the format version). May, for example, reject an invalid or unsupported wire format.
V8_WARN_UNUSED_RESULT bool ReadRawBytes | ( | size_t | length, |
const void ** | data | ||
) |
V8_WARN_UNUSED_RESULT bool 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.
V8_WARN_UNUSED_RESULT bool ReadUint64 | ( | uint64_t * | value | ) |
V8_WARN_UNUSED_RESULT MaybeLocal<Value> ReadValue | ( | Local< Context > | context | ) |
Deserializes a JavaScript value from the buffer.
void 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.
void TransferArrayBuffer | ( | uint32_t | transfer_id, |
Local< ArrayBuffer > | array_buffer | ||
) |
Accepts the array buffer corresponding to the one passed previously to ValueSerializer::TransferArrayBuffer.
void 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.
