Interface CalendarHashChain

public interface CalendarHashChain

Calendar hash chains are represented by `calendar chain' structures that consist of:

• index fields: `publication time' and `aggregation time';
• an `input hash': the input for the computation specified by the hash chain;
• a sequence of `left link' and `right link' structures.

Each link field contains a hash value from the calendar hash tree.

Constant Field Values

Method Detail

getInputHash

DataHash getInputHash()

Returns the input hash of the calendar hash chain

getOutputHash

DataHash getOutputHash()

Returns the output hash of the calendar hash chain

getAggregationTime

Date getAggregationTime()

Returns the aggregation time, as written in the hash chain record.

Note that while in an internally consistent signature this is the same as the signature registration time encoded in the shape of the hash chain, we can't just assume the input data to be consistent.

Returns:

the aggregation time. always present.

getPublicationTime

Date getPublicationTime()

Returns the publication time of the calendar hash chain

getChainLinks

List<CalendarHashChainLink> getChainLinks()

Returns the left and right chain links
