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.
|
overridedefault |
Override the destructor to manage the life cycle of the underlying buffer.
|
protecteddefault |
|
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.
|
pure virtual |
The string data from the underlying buffer. If the resource is cacheable then data() must return the same value for all invocations.
|
pure virtual |
The length of the string. That is, the number of two-byte characters.
void UpdateDataCache | ( | ) |
Update {cached_data_} with the data from the underlying buffer. This can be called only for cacheable resources.
