Detailed Description

An ExternalStringResource is a wrapper around a two-byte string buffer that resides outside V8's heap. Implement an ExternalStringResource to manage the life cycle of the underlying buffer. Note that the string data must be immutable.

Member Function Documentation

virtual const uint16_t* data ( ) const

pure virtual

The string data from the underlying buffer.
