Constructor Detail

CallbackHandlerCredentialSource

public CallbackHandlerCredentialSource(CallbackHandler callbackHandler)

Construct a new instance.

Parameters:

callbackHandler - the callback handler to use (must not be null)

Method Detail

getCredentialAcquireSupport

public SupportLevel getCredentialAcquireSupport(Class<? extends Credential> credentialType,
                                                String algorithmName,
                                                AlgorithmParameterSpec parameterSpec)
                                         throws IOException

Description copied from interface: CredentialSource

Determine whether a given credential is definitely obtainable, possibly obtainable, or definitely not obtainable.

Specified by:

getCredentialAcquireSupport in interface CredentialSource

Parameters:

credentialType - the credential type class (must not be null)

algorithmName - the algorithm name, or null if any algorithm is acceptable or the credential type does not support algorithm names

parameterSpec - the algorithm parameters to match, or null if any parameters are acceptable or the credential type does not support algorithm parameters

Returns:

the level of support for this credential type (not null)

Throws:

IOException - if the credential source failed to determine the support level

getCredential

public <C extends Credential> C getCredential(Class<C> credentialType,
                                              String algorithmName,
                                              AlgorithmParameterSpec parameterSpec)
                                       throws IOException

Description copied from interface: CredentialSource

Acquire a credential of the given type. The credential type is defined by its Class and an optional algorithmName. If the algorithm name is not given, then the query is performed for any algorithm of the given type.

Specified by:

getCredential in interface CredentialSource

Type Parameters:

C - the credential type

Parameters:

credentialType - the credential type class (must not be null)

algorithmName - the algorithm name, or null if any algorithm is acceptable or the credential type does not support algorithm names

parameterSpec - the algorithm parameters to match, or null if any parameters are acceptable or the credential type does not support algorithm parameters

Returns:

the credential, or null if the principal has no credential of that type

Throws:

IOException - if the realm is not able to handle requests for any reason
