    • Method Detail

      • registerIdentity

        public void registerIdentity​(int nId)
        This method is invoked when an identity is encountered in the POF stream. The identity is used to uniquely identify the next value in the POF stream, and can be later referenced by the PofHandler.onIdentityReference(int, int) method.
        Specified by:
        registerIdentity in interface PofHandler
        Parameters:
        nId - if (nId >= 0), then this is the identity encountered in the POF stream, otherwise it is an indicator that the following value could have been assigned an identifier but was not (i.e. that the subsequent value is of a referenceable data type)
