Examples of sun.security.util.DerInputStream.available()

sun.security.util.DerInputStream.available()
Returns the number of bytes available for reading. This is most useful for testing whether the stream is empty.

        if ((val.data == null) || (val.data.available() == 0)) {
            return;
        }


        DerInputStream in = val.data;
        while (in != null && in.available() != 0) {
            DerValue opt = in.getDerValue();


            if (opt.isContextSpecific(TAG_DISTRIBUTION_POINT) &&
                opt.isConstructed()) {
                distributionPoint =
