,CheckedListProof
public class CheckedListProofImpl<E> extends Object implements CheckedListProof
A checked list proof includes list proof verification results.If it is correct you may access:
- a calculated index hash of corresponding collection
- proof elements
If the proof is the proof of absence, then empty collection of elements is returned.
If the proof is not valid, you may get the verification status using
getProofStatus()
with description of why the proof is not valid.

getElements
public NavigableMap<Long,E> getElements()
Description copied from interface:CheckedListProof
Get all list proof elements. There might be several consecutive ranges.- Specified by:
getElements
in interfaceCheckedListProof<E>
- Returns:
- list proof elements. Empty if the proof is a proof of absence
-
getIndexHash
public HashCode getIndexHash()
Description copied from interface:CheckedProof
Returns the calculated index hash of the proof. Must be equal to the index hash of the collection, providing this proof.- Specified by:
getIndexHash
in interfaceCheckedProof

getProofStatus
public ListProofStatus getProofStatus()
Description copied from interface:CheckedListProof
Returns the status of this proof: whether it is structurally valid.- Specified by:
getProofStatus
in interfaceCheckedListProof<E>
- Specified by:
getProofStatus
in interfaceCheckedProof

isValid
public boolean isValid()
Description copied from interface:CheckedProof
Returns true if proof status is valid, false otherwise. Details about the proof verification status could be obtained viaCheckedProof.getProofStatus()
.- Specified by:
