-
-// Serialization format is a sequence of tags followed by zero or more data
-// arguments.  Tags always take exactly one byte. A serialized stream first
-// begins with a complete VersionTag. If the stream does not begin with a
-// VersionTag, we assume that the stream is in format 0.
-
-// Tags which are not interpreted by Blink (but instead by V8) are omitted here.
-
-// This format is private to the implementation of SerializedScriptValue. Do not
-// rely on it externally. It is safe to persist a SerializedScriptValue as a
-// binary blob, but this code should always be used to interpret it.
-
-// WebCoreStrings are read as (length:uint32_t, string:UTF8[length]).
-// RawStrings are read as (length:uint32_t, string:UTF8[length]).
-// RawUCharStrings are read as
-//     (length:uint32_t, string:UChar[length/sizeof(UChar)]).
-// RawFiles are read as
-//     (path:WebCoreString, url:WebCoreStrng, type:WebCoreString).
-// There is a reference table that maps object references (uint32_t) to
-// v8::Values.
-// Tokens marked with (ref) are inserted into the reference table and given the
-// next object reference ID after decoding.
-// All tags except InvalidTag, PaddingTag, ReferenceCountTag, VersionTag,
-// GenerateFreshObjectTag and GenerateFreshArrayTag push their results to the
-// deserialization stack.
-// There is also an 'open' stack that is used to resolve circular references.
-// Objects or arrays may contain self-references. Before we begin to deserialize
-// the contents of these values, they are first given object reference IDs (by
-// GenerateFreshObjectTag/GenerateFreshArrayTag); these reference IDs are then
-// used with ObjectReferenceTag to tie the recursive knot.
