addTask
protected void addTask(String key, ConcurrentHashMapKeycloakTransaction.MapTaskWithValue task)
Adds a given task if not exists for the given key
-
registerEntityForChanges
public V registerEntityForChanges(V origEntity)
Returns a deep clone of an entity. If the clone is already in the transaction, returns this one.Usually used before giving an entity from a source back to the caller, to prevent changing it directly in the data store, but to keep transactional properties.
- Parameters:
origEntity
- Original entity- Returns:
-
read
public V read(String sKey)
Description copied from interface:MapKeycloakTransaction
Provides possibility to lookup for values by akey
in the underlying store with respect to changes done in current transaction. Updates to the returned instance would be visible in the current transaction and will propagate into the underlying store upon commit. IfV
implementsExpirableEntity
this method should not return entities that are expired. SeeExpirableEntity
JavaDoc for more details.- Specified by:
read
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
sKey
- identifier of a value- Returns:
- a value associated with the given
key
-
read
public Stream<V> read(QueryParameters<M> queryParameters)
Returns the stream of records that match given criteria and includes changes made in this transaction, i.e. the result contains updates and excludes records that have been deleted in this transaction.- Specified by:
read
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
queryParameters
-- Returns:
-
getCount
public long getCount(QueryParameters<M> queryParameters)
Description copied from interface:MapKeycloakTransaction
Returns a number of values present in the underlying storage that fulfill the given criteria with respect to changes done in the current transaction.- Specified by:
getCount
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
queryParameters
- parameters for the query like firstResult, maxResult, requested ordering, etc.- Returns:
- number of values present in the storage that fulfill the given criteria
-
create
public V create(V value)
Description copied from interface:MapKeycloakTransaction
Instructs this transaction to add a new value into the underlying store on commit.Updates to the returned instances of
V
would be visible in the current transaction and will propagate into the underlying store upon commit. The ID of the entity passed in the parameter might change to a different value in the returned value if the underlying storage decided this was necessary. If the ID of the entity was null before, it will be set on the returned value.- Specified by:
create
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
value
- the value- Returns:
- Entity representing the
value
in the store. It may or may not be the same instance asvalue
.
-
delete
public boolean delete(String key)
Description copied from interface:MapKeycloakTransaction
Instructs this transaction to delete a value associated with the identifierkey
from the underlying store on commit.- Specified by:
delete
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
key
- identifier of a value- Returns:
- Returns
true
if the object has been deleted or result cannot be determined,false
otherwise.
-
delete
public long delete(QueryParameters<M> queryParameters)
Description copied from interface:MapKeycloakTransaction
Instructs this transaction to remove values (identified bymcb
filter) from the underlying store on commit.- Specified by:
delete
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
queryParameters
- parameters for the query like firstResult, maxResult, requested ordering, etc.- Returns:
- number of removed objects (might return
-1
if not supported)
-
exists
public boolean exists(String key)
Description copied from interface:MapKeycloakTransaction
Returnstrue
if the object with the givenkey
exists in the underlying storage with respect to changes done in current transaction.false
otherwise.- Specified by:
exists
in interfaceMapKeycloakTransaction<K,V extends AbstractEntity & UpdatableEntity>
- Parameters:
key
- Key of the object. Must not benull
.- Returns:
- See description
-
getRealmId
public String getRealmId()
Description copied from interface:HasRealmId
Returns realm ID of the entity.- Specified by:
getRealmId
in interfaceHasRealmId
- Returns:
- See description
-
setRealmId
public void setRealmId(String realmId)
Description copied from interface:HasRealmId
Sets the realm ID of this object.- Specified by:
setRealmId
in interfaceHasRealmId
- Parameters:
realmId
- Realm ID.
