Method Details

getMode

Mode<?> getMode()

Returns the mode that was supplied to the initial invocation.

getContext

Context getContext()

Returns the current persist context in use.

getContextManager

ContextManager getContextManager()

getPersistenceService

PersistenceService getPersistenceService()

getQueryBuilderFactory

QueryBuilderFactory getQueryBuilderFactory()

Returns the QueryBuilderFactory service.

perform

<A,
T> Optional<T> perform(PersistTask<A,T> task,
 Optional<A> arg)
                    throws Exception

Performs the given command with the same mode as supplied to the parent invocation without wrapping PersistExceptions, but instead propagating them. This can be used to execute nested commands.

Throws:

Exception

perform

<A,
T> Optional<T> perform(PersistTask<A,T> task,
 A arg)
                    throws Exception

Performs the given command with the same mode as supplied to the parent invocation without wrapping PersistExceptions, but instead propagating them. This can be used to execute nested commands.

Throws:

Exception

perform

<A,
T> Optional<T> perform(PersistTask<A,T> task)
                    throws Exception

Performs the given command with the same mode as supplied to the parent invocation without wrapping PersistExceptions, but instead propagating them. This can be used to execute nested commands. The argument `Optional.empty()` is passed to the given task.

Throws:

Exception

perform

<A,
T,
E extends Exception> Optional<T> perform(Mode<E> mode,
 PersistTask<A,T> task,
 Optional<A> arg)
                                         throws E

Performs the given command with the given mode. That is the same as CommandExecutor.perform(Mode, PersistTask, Object).

Type Parameters:

A - type of input to the task

T - result type of the task

E - exception type

Throws:

E

using

CommandContext using(Context context)

Creates a copy of this CommandContext but using a different Context. This method is useful if a nested task should be executed with a different context.
