Base structure.
Handle retrieval the accessor value identified by |name|. |object| is the receiver ('this' object) of the accessor. If retrieval succeeds set |retval| to the return value. If retrieval fails set |exception| to the exception that will be thrown. Return true (1) if accessor retrieval was handled.
Handle assignment of the accessor value identified by |name|. |object| is the receiver ('this' object) of the accessor. |value| is the new value being assigned to the accessor. If assignment fails set |exception| to the exception that will be thrown. Return true (1) if accessor assignment was handled.
Structure that should be implemented to handle V8 accessor calls. Accessor identifiers are registered by calling cef_v8value_t::set_value(). The functions of this structure will be called on the thread associated with the V8 accessor.
