Method Detail

handles

public boolean handles(XMLObject keyInfoChild)

Evaluate whether the given provider should attempt to handle resolving a credential from the specified KeyInfo child. An evaluation of true does not guarantee that a credential can or will be extracted form the particular KeyInfo child, only that processing should be attempted.

Parameters:

keyInfoChild - the KeyInfo child object to consider

Returns:

true if the provider should attempt to resolve credentials, false otherwise

process

public Collection<Credential> process(KeyInfoCredentialResolver resolver,
                             XMLObject keyInfoChild,
                             CriteriaSet criteriaSet,
                             KeyInfoResolutionContext kiContext)
                               throws SecurityException

Process a specified KeyInfo child (XMLobject) and attempt to resolve a credential from it.

Parameters:

resolver - reference to a resolver which is calling the provider

keyInfoChild - the KeyInfo child being processed

criteriaSet - the credential criteria the credential must satisfy

kiContext - the resolution context, used for sharing state amongst resolvers and providers

Returns:

a resolved Credential collection, or null

Throws:

SecurityException - if there is an error during credential resolution. Note: failure to resolve a credential is not an error.

getDSAKeyValue

protected DSAKeyValue getDSAKeyValue(XMLObject xmlObject)

Get the DSAKeyValue from the passed XML object.

Parameters:

xmlObject - an XML object, presumably either a KeyValue or an DSAKeyValue

Returns:

the DSAKeyValue which was found, or null if none
