      • 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

         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.
        required bytes chain_code = 1;
        Specified by:
        getChainCode in interface Protos.DeterministicKeyOrBuilder
        Returns:
        The chainCode.

      • getPathList

        public java.util.List<java.lang.Integer> getPathList()
         The path through the key tree. Each number is encoded in the standard form: high bit set for private derivation
 and high bit unset for public derivation.
        repeated uint32 path = 2;
        Specified by:
        getPathList in interface Protos.DeterministicKeyOrBuilder
        Returns:
        A list containing the path.

      • getPathCount

        public int getPathCount()
         The path through the key tree. Each number is encoded in the standard form: high bit set for private derivation
 and high bit unset for public derivation.
        repeated uint32 path = 2;
        Specified by:
        getPathCount in interface Protos.DeterministicKeyOrBuilder
        Returns:
        The count of path.

      • getPath

        public int getPath​(int index)
         The path through the key tree. Each number is encoded in the standard form: high bit set for private derivation
 and high bit unset for public derivation.
        repeated uint32 path = 2;
        Specified by:
        getPath in interface Protos.DeterministicKeyOrBuilder
        Parameters:
        index - The index of the element to return.
        Returns:
        The path at the given index.

      • 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
        Returns:
        Whether the issuedSubkeys field is set.

        Returns:
        The issuedSubkeys.

      • hasIsFollowing

        public boolean hasIsFollowing()
        
 Flag indicating that this key is a root of a following chain. This chain is following the next non-following chain.
 Following/followed chains concept was used for married keychains, where the set of keys combined together to produce
 a single P2SH multisignature address. It is currently unused, but this flag is preserved.
        optional bool isFollowing = 5;
        Specified by:
        hasIsFollowing in interface Protos.DeterministicKeyOrBuilder
        Returns:
        Whether the isFollowing field is set.

      • getIsFollowing

        public boolean getIsFollowing()
        
 Flag indicating that this key is a root of a following chain. This chain is following the next non-following chain.
 Following/followed chains concept was used for married keychains, where the set of keys combined together to produce

      • hasSigsRequiredToSpend

        public boolean hasSigsRequiredToSpend()
         Number of signatures required to spend. This field was needed only for married keychains to reconstruct KeyChain
 and represents the N value from N-of-M CHECKMULTISIG script. It is currently unused, but this number is preserved.
 For regular single keychains it will always be 1.
        optional uint32 sigsRequiredToSpend = 6 [default = 1];
        Specified by:
        hasSigsRequiredToSpend in interface Protos.DeterministicKeyOrBuilder
        Returns:
        Whether the sigsRequiredToSpend field is set.

      • getSigsRequiredToSpend

        public int getSigsRequiredToSpend()
         Number of signatures required to spend. This field was needed only for married keychains to reconstruct KeyChain
