                                         throws oracle.security.xmlsec.dsig.ReferenceException,
                                                oracle.security.crypto.core.AlgorithmIdentifierException,
                                                oracle.security.xmlsec.transform.TransformationException

Find out what the reference is pointing to by performing all transforms, except the canonicalization ones.

Transforms

• Performs all the Xpath like transforms - XPathFilter, XPathFilter2, DecryptTransform and EnvelopedSignatureTranform
• Ignores any SWA attachment transforms, simply returns the AttachmentPart whenever there is cid: URI
• Throws an exception If there is an XSLTTransform
• Returns a byte array if there is a Base64Decode transform
• Resolves the STRs, and returns a map of STRs to STs if there is a STRTransform, But does not do any canonicalization
• Ignores any canonicalization transform, but throws an exception is the canonicalization transform is not the last one

Parameters:

ref - the reference to be resolved

msg - the soap messages - only used for resolving cid: references

STRToST - if a non null Map is passed in and if there is an STRTransform this reference's list of transforms, then the STRToST will be filled up a mapping of WSSecurityTokenReference objects to corresponding WSSecurityToken objects. The WSSecurityToken objects are obtained by following the KeyRetrievers

Returns:

• An AttachmentPart object if it this a cid: reference
• A byte[] is there a Base64Decode transform
• A String if this is an external reference (simply returns the URI)
• A Node if this is an internal reference to single complete subtree.
  This happens when a) ID based referencing is used or b) an XPath filter 2.0 with only one intersect filter that selects a single node is used.
• A Set containing Nodes , if it an internal reference to anything other than a single complete subtree, i.e. either a single incomplete subtree or multiple subtrees whether complete or incomplete.
  E.g. an XPath Filter 2.0 of type subtract can make a subtree incomplete, and so can an EnvelopedSignatureTransform

Throws:

oracle.security.xmlsec.dsig.ReferenceException - if a reference cannot be resolved, of if the transform has invalid syntax, or if there is

oracle.security.crypto.core.AlgorithmIdentifierException - if there is a unrecognized transform
or if there is any Base64 or XSLT transform,
or if there is any transform following a C14N or STR transform

oracle.security.xmlsec.transform.TransformationException
