Method Detail

getInstance

public static ArchiveTimeStamp getInstance(java.lang.Object obj)

Return an ArchiveTimestamp from the given object.

Parameters:

obj - the object we want converted.

Returns:

an ArchiveTimestamp instance, or null.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getDigestAlgorithmIdentifier

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getDigestAlgorithmIdentifier()

getTimeStampDigestValue

public byte[] getTimeStampDigestValue()

getDigestAlgorithm

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getDigestAlgorithm()

Return the contents of the digestAlgorithm field - null if not set.

Returns:

the contents of the digestAlgorithm field, or null if not set.

getHashTreeLeaf

public PartialHashtree getHashTreeLeaf()

Return the first node in the reduced hash tree which contains the leaf node.

Returns:

the node containing the data hashes, null if no reduced hash tree is present.

getReducedHashTree

public PartialHashtree[] getReducedHashTree()

getTimeStamp

public ContentInfo getTimeStamp()

toASN1Primitive

public org.bouncycastle.asn1.ASN1Primitive toASN1Primitive()
