    • Method Detail

      • hasChainCode

        public boolean hasChainCode()
         Random data that allows us to extend a key. Without this, we can't figure out the next key in the chain and
 should just treat it as a regular ORIGINAL type key.

        Specified by:
        hasChainCode in interface Protos.DeterministicKeyOrBuilder
        Returns:
        Whether the chainCode field is set.

      • getChainCode

        public com.google.protobuf.ByteString getChainCode()

      • hasIssuedSubkeys

        public boolean hasIssuedSubkeys()
         How many children of this key have been issued, that is, given to the user when they requested a fresh key?
 For the parents of keys being handed out, this is always less than the true number of children: the difference is
 called the lookahead zone. These keys are put into Bloom filters so we can spot transactions made by clones of
 this wallet - for instance when restoring from backup or if the seed was shared between devices.

 If this field is missing it means we're not issuing subkeys of this key to users.
        optional uint32 issued_subkeys = 3;
        Specified by:
        hasIssuedSubkeys in interface Protos.DeterministicKeyOrBuilder
