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.

Constructor & Destructor Documentation

◆ ~ExternalStringResource()

~ExternalStringResource ( )

overridedefault

Override the destructor to manage the life cycle of the underlying buffer.

ExternalStringResource ( )

Member Function Documentation

◆ cached_data()

const uint16_t * cached_data ( ) const

inline

Returns the cached data from the underlying buffer. This method can be called only for cacheable resources (i.e. IsCacheable() == true) and only after UpdateDataCache() was called.

Definition at line 305 of file v8-primitive.h.

◆ data()

virtual const uint16_t * data ( ) const

pure virtual

The string data from the underlying buffer. If the resource is cacheable then data() must return the same value for all invocations.

◆ length()

virtual size_t length ( ) const

pure virtual

The length of the string. That is, the number of two-byte characters.

◆ UpdateDataCache()

void UpdateDataCache ( )

Update {cached_data_} with the data from the underlying buffer. This can be called only for cacheable resources.
