Constructor Details

AbstractEvidenceRecordRenewalDigestBuilderHelper

protected AbstractEvidenceRecordRenewalDigestBuilderHelper(DefaultEvidenceRecord evidenceRecord)

Creates an instance of AbstractEvidenceRecordRenewalDigestBuilderHelper allowing to build hash for XmlEvidenceRecord's renewal. Builds digest for the last available ArchiveTimeStamp or ArchiveTimeStampChain, based on the called method.

Parameters:

evidenceRecord - DefaultEvidenceRecord

Method Details

getArchiveTimeStampChainObject

protected ArchiveTimeStampChainObject getArchiveTimeStampChainObject(ArchiveTimeStampObject archiveTimeStampObject)

Returns an ArchiveTimeStampChainObject corresponding to the given archiveTimeStampObject

Parameters:

archiveTimeStampObject - ArchiveTimeStampObject to get ArchiveTimeStampChainObject for

Returns:

ArchiveTimeStampChainObject

buildTimeStampRenewalDigest

public abstract DSSMessageDigest buildTimeStampRenewalDigest(ArchiveTimeStampObject archiveTimeStamp)

This method builds digest for a time-stamp renewal using a digest algorithm from the

Parameters:

archiveTimeStamp - ArchiveTimeStampObject to build digest on

Returns:

Digest

buildArchiveTimeStampSequenceDigest

public abstract DSSMessageDigest buildArchiveTimeStampSequenceDigest(ArchiveTimeStampChainObject archiveTimeStampChain)

Builds digest for renewal of the hash-tree, considering the provided archiveTimeStampChainObject as the last chain in the evidence record. Note: this method build digest solely for ArchiveTimeStampChainObject without considering detached content. Please use #buildHashTreeRenewalDigestGroup method instead fo hash calculation in case of a hash-tree renewal with a new time-stamp

Parameters:

archiveTimeStampChain - ArchiveTimeStampChainObject

Returns:

DSSMessageDigest

getNextArchiveTimeStampChain

protected ArchiveTimeStampChainObject getNextArchiveTimeStampChain(ArchiveTimeStampChainObject archiveTimeStampChainObject)

Returns the next chronologically ordered ArchiveTimeStampChainObject

Parameters:

archiveTimeStampChainObject - ArchiveTimeStampChainObject to get a parent for

Returns:

ArchiveTimeStampChainObject
