Method Detail

isValid

public static boolean isValid(org.opensaml.xml.XMLObject xmlObject)

Checks to see if the given XMLObject is still valid. An XMLObject is valid if, and only if, itself and every ancestral TimeBoundSAMLObject is valid.

Parameters:

xmlObject - the XML object tree to check

Returns:

true of the tree is valid, false if not

getEarliestExpiration

public static org.joda.time.DateTime getEarliestExpiration(org.opensaml.xml.XMLObject xmlObject)

Gets the earliest expiration instant for a XMLObject. This method traverses the tree of SAMLObject rooted at the given object and calculates the earliest expiration as the earliest of the following two items:

• the earliest validUntil time on a TimeBoundSAMLObject
• the shortest duration on a CacheableSAMLObject added to the current time

Parameters:

xmlObject - the XML object tree to get the earliest expiration time from

Returns:

the earliest expiration time

getEarliestExpiration

public static org.joda.time.DateTime getEarliestExpiration(org.opensaml.xml.XMLObject xmlObject,
                                                           org.joda.time.DateTime earliestExpiration,
                                                           org.joda.time.DateTime now)

Gets the earliest expiration instant within a metadata tree.

Parameters:

xmlObject - the metadata

earliestExpiration - the earliest expiration instant

now - when this method was called

Returns:

the earliest expiration instant within a metadata tree
