Method Detail

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

getContext

public ome.system.OmeroContext getContext()

Description copied from interface: Executor

Provides access to the context for Work-API consumers who need to publish events, etc.

Specified by:

getContext in interface Executor

principal

public ome.system.Principal principal()

Description copied from interface: Executor

Returns a Principal representing your current session or null, if none is active.

Specified by:

principal in interface Executor

execute

public <T> T execute(ome.system.Principal p,
                     Executor.Work<T> work)

Call execute(Map, Principal, Work) with a null call context.

Specified by:

execute in interface Executor

execute

public <T> T execute(java.util.Map<java.lang.String,java.lang.String> callContext,
                     ome.system.Principal p,
                     Executor.Work<T> work)

Executes a Executor.Work instance wrapped in two layers of AOP. The first is intended to acquire the proper arguments for Executor.Work.doWork(Session, ServiceFactory) for the OmeroContext, and the second performs all the standard service actions for any normal method call. If the Principal argument is not null, then additionally, a login/logout sequence will be performed in a try/finally block.

Specified by:

execute in interface Executor

Parameters:

callContext - Possibly null key-value map. See #3529

p -

work -

Returns:

See above.

submit

public <T> java.util.concurrent.Future<T> submit(java.util.concurrent.Callable<T> callable)

Description copied from interface: Executor

Call Executor.submit(Map, Callable) with a null callContext.

Specified by:

submit in interface Executor

Returns:

See above.
