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()

v8::String::ExternalStringResource::~ExternalStringResource ( )

overridedefault

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

◆ ExternalStringResource()

v8::String::ExternalStringResource::ExternalStringResource ( )

protecteddefault

Member Function Documentation

◆ cached_data()

const uint16_t * v8::String::ExternalStringResource::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.

◆ data()

virtual const uint16_t * v8::String::ExternalStringResource::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 v8::String::ExternalStringResource::length ( ) const

pure virtual

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

◆ UpdateDataCache()

void v8::String::ExternalStringResource::UpdateDataCache ( )

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