Detailed Description

An ExternalOneByteStringResource is a wrapper around an one-byte string buffer that resides outside V8's heap. Implement an ExternalOneByteStringResource to manage the life cycle of the underlying buffer. Note that the string data must be immutable and that the data must be Latin-1 and not UTF-8, which would require special treatment internally in the engine and do not allow efficient indexing. Use String::New or convert to 16 bit data for non-Latin1.
