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.

Constructor & Destructor Documentation

◆ ~ExternalOneByteStringResource()

~ExternalOneByteStringResource ( )

overridedefault

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

◆ ExternalOneByteStringResource()

ExternalOneByteStringResource ( )

protecteddefault

Member Function Documentation

◆ cached_data()

const char* cached_data ( ) const

inline

Returns the cached data from the underlying buffer. If the resource is uncacheable or if UpdateDataCache() was not called before, it has undefined behaviour.

Definition at line 358 of file v8-primitive.h.

◆ data()

virtual const char* 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 number of Latin-1 characters in the string.

◆ UpdateDataCache()

void UpdateDataCache ( )

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