Class LdapAdapter

java.lang.Object

org.forgerock.openam.cts.impl.LdapAdapter

All Implemented Interfaces:

TokenStorageAdapter

public class LdapAdapter
extends Object
implements TokenStorageAdapter

Responsible adapting the LDAP SDK Connection and its associated domain values into Tokens. This class will manage the associated conversion tasks and present a common interface to calling classes. It also helps us work around a number of final classes in the SDK which were hindering unit testing.

Constructor Detail

LdapAdapter

@Inject
public LdapAdapter(LdapTokenAttributeConversion conversion,
                   LdapQueryFilterVisitor queryConverter,
                   LdapQueryFactory queryFactory,
                   LdapConnectionFactoryProvider connectionFactoryProvider,
                   Map<org.forgerock.util.Option<?>,LdapOptionFunction> optionFunctionMap)

Create an instance of this adapter.

Parameters:

conversion - Non null, required for Token conversion.

queryConverter - For converting between CTS and LDAP.

queryFactory - Produces queries.

connectionFactoryProvider - Produces connection factories for connections to the datastore.

Method Detail

create

public Token create(Token token,
                    org.forgerock.util.Options options)
             throws DataLayerException

Create the Token in LDAP.

Specified by:

create in interface TokenStorageAdapter

Parameters:

token - Non null Token to create.

options - Non null Options for the operations.

Returns:

A copy of the created Token with the ETag set.

Throws:

DataLayerException - If the operation failed, this exception will capture the reason.

read

public Token read(String tokenId,
                  org.forgerock.util.Options options)
           throws DataLayerException

Performs a read against the LDAP connection and converts the result into a Token.

Specified by:

read in interface TokenStorageAdapter

Parameters:

tokenId - The id of the Token to read.

options - Non null Options for the operations.

Returns:

Token if found, otherwise null.

Throws:

DataLayerException - If the operation failed, this exception will capture the reason.

update

public Token update(Token previous,
                    Token updated,
                    org.forgerock.util.Options options)
             throws DataLayerException

Update the Token based on whether there were any changes between the two. It is up to the underlying ldap later to update the etag so the etag so the etag is removed from the previous and updated token before the diff is computed.

If the previous Token contains a non-null CoreTokenField.ETAG attribute value then the update will be performed with an optimistic concurrency check. If it does not contain the attribute or it contains a null value the update will be performed without any concurrency checks.

Specified by:

update in interface TokenStorageAdapter

Parameters:

previous - The non null previous Token to check against.

options - The non null Options for the operation.

updated - The non null Token to update with.

Returns:

A copy of the updated token. The token would contain the updated etag.

Throws:

OptimisticConcurrencyCheckFailedException - If the operation failed due to an assertion on the tokens ETag. Only possible if the CoreTokenField.ETAG attribute is present on the previous token.

DataLayerException - If the operation failed for a known reason.

delete

public PartialToken delete(String tokenId,
                           org.forgerock.util.Options options)
                    throws DataLayerException

Performs a delete against the Token ID provided.

If the etag parameter is a non-null value then the delete will be performed with an optimistic concurrency check. If it is null then the delete will be performed without any concurrency checks.

Specified by:

delete in interface TokenStorageAdapter

Parameters:

tokenId - The non null Token ID to delete.

options - The non null Options for the operation.

Returns:

A PartialToken containing at least the CoreTokenField.TOKEN_ID.

Throws:

DataLayerException - If the operation failed, this exception will capture the reason.

OptimisticConcurrencyCheckFailedException - If the operation failed due to an assertion on the tokens ETag.

query

public Collection<Token> query(TokenFilter query)
                        throws DataLayerException

Description copied from interface: TokenStorageAdapter

Specified by:

query in interface TokenStorageAdapter

Parameters:

query - The non null filter specification.

Throws:

DataLayerException - If the operation failed, this exception will capture the reason.

partialQuery

public Collection<PartialToken> partialQuery(TokenFilter query)
                                      throws DataLayerException

Performs a partial query using the provided filter.

Specified by:

partialQuery in interface TokenStorageAdapter

Parameters:

query - The non null filter specification.

Throws:

DataLayerException - If the operation failed, this exception will capture the reason.

startContinuousQuery

public ContinuousQuery startContinuousQuery(TokenFilter filter,
                                            ContinuousQueryListener listener)
                                     throws DataLayerException

Description copied from interface: TokenStorageAdapter

Performs a continuous query using the provided filter.

Specified by:

startContinuousQuery in interface TokenStorageAdapter

Parameters:

filter - The non null filter specification.

Throws:

DataLayerException - If the operation failed, this exception will capture the reason.
