getNextSeqId

default Long getNextSeqId(String seqName)

Get the next guaranteed unique seq id from the sequence with the given sequence name; if the named sequence doesn't exist, it will be created.

From v1.3.0 this is equivalent of calling getNextSeqId(String, boolean) with true as second parameter.

Parameters:

seqName - The name of the sequence to get the next seq id from

Returns:

Long with the next seq id for the given sequence name

getNextSeqId

Long getNextSeqId(String seqName,
 boolean clusterMode)

Get the next guaranteed unique seq id from the sequence with the given sequence name; if the named sequence doesn't exist, it will be created.

If the instance should be running in cluster mode then it will try a SELECT FOR UPDATE approach to retrieving the next bank of sequence ids, to avoid potential collisions with other nodes.

If not in cluster mode, this is not required, and the existing JVM synchronization locking is enough.

It will be in clusterMode if true is passed as a parameter, or if EntityConfigUtil.DelegatorInfo.useDistributedCacheClear is enabled

Parameters:

seqName - The name of the sequence to get the next seq id from

clusterMode - Is this a node in a clustered instance or not

Returns:

Long with the next seq id for the given sequence name

Since:

v1.3.0

transform

List<GenericValue> transform(String entityName,
 EntityCondition entityCondition,
 List<String> orderBy,
 String lockField,
 Transformation transformation)
                      throws GenericEntityException

Applies the given transformation to any entities matching the given condition.

Parameters:

entityName - the type of entity to transform (required)

entityCondition - the condition that selects the entities to transform (null means transform all)

orderBy - the order in which the entities should be selected for updating (null means no ordering)

lockField - the entity field to use for optimistic locking; the value of this field will be read between the SELECT and the UPDATE to determine whether another process has updated one of the target records in the meantime; if so, the transformation will be reapplied and another UPDATE attempted

transformation - the transformation to apply (required)

Returns:

the transformed entities in the order they were selected (never null)

Throws:

GenericEntityException
