Member Function Documentation

◆ data()

const char * v8::ExternalOwningOneByteStringResource::data ( ) const
inlineoverridevirtual

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

Implements v8::String::ExternalOneByteStringResource.

◆ length()

size_t v8::ExternalOwningOneByteStringResource::length ( ) const
inlineoverridevirtual

The number of Latin-1 characters in the string.

Implements v8::String::ExternalOneByteStringResource.
