getTransactionTemplateIfJoinable

public <T extends Serializable>
Optional<org.springframework.transaction.support.TransactionTemplate> getTransactionTemplateIfJoinable(PersistentTask<T> task)

Returns a TransactionTemplate if the task and the framework may join transaction.

assertIsKnown

@NonNull
public <T extends Serializable> PersistentTask<T> assertIsKnown(@NonNull
 TaskId<T> id)

Check if the PersistentTask is known or not.

Type Parameters:

T - the state type

Parameters:

id - the TaskId of the PersistentTask

Returns:

the PersistentTask registered to the given id

Throws:

IllegalStateException - if the id is unknown

register

public TaskId<Serializable> register(String name,

register

public <T extends Serializable> TaskId<T> register(String name,
 PersistentTask<T> task)

A way to manually register a PersistentTask, usually not needed as spring beans will be added automatically.

register

public <T extends Serializable> TaskId<T> register(TaskId<T> id,
 PersistentTask<T> task)

A way to manually register a PersistentTask, usually not needed as spring beans will be added automatically.

replace

public <T extends Serializable> TaskId<T> replace(String name,
 PersistentTask<T> task)

A way to manually register a PersistentTask, usually not needed as spring beans will be added automatically.

replace

public <T extends Serializable> TaskId<T> replace(TaskId<T> id,
 PersistentTask<T> task)

A way to manually register a PersistentTask, usually not needed as spring beans will be added automatically.
