Method Summary

Modifier and Type	Method	Description

void	addProcessor(ProcessorPrx proc, Ice.Current __current)	Registers a Processor for Storm notifications so that other sessions can query whether or not a given processor would accept a given task.
boolean	areTablesEnabled(Ice.Current __current)	Returns true if a Tables service is active in the grid.
RepositoryPrx	getScriptRepository(Ice.Current __current)	Returns the single (possibly mirrored) script repository which makes all official scripts available.

Method Detail

setServiceFactory

public void setServiceFactory(ServiceFactoryI sf)
                       throws ServerError

Specified by:

setServiceFactory in interface ServiceFactoryAware

Throws:

ServerError

preClose

protected void preClose(Ice.Current current)

Specified by:

preClose in class AbstractCloseableAmdServant

postClose

protected void postClose(Ice.Current current)

Description copied from class: AbstractCloseableAmdServant

Should not throw any exceptions which should be detected by clients since it is called in a finally block after the client thread has been released.

Specified by:

postClose in class AbstractCloseableAmdServant

getScriptRepository

public RepositoryPrx getScriptRepository(Ice.Current __current)
                                  throws ServerError

Description copied from interface: _SharedResourcesOperations

Returns the single (possibly mirrored) script repository which makes all official scripts available.

Specified by:

getScriptRepository in interface _SharedResourcesOperations

Parameters:

__current - The Current object for the invocation.

Throws:

ServerError

repositories

public RepositoryMap repositories(Ice.Current current)
                           throws ServerError

Description copied from interface: _SharedResourcesOperations

Returns a map between Repository descriptions (omero::model::OriginalFile instances) and RepositoryPrx instances (possibly null).

Specified by:

repositories in interface _SharedResourcesOperations

Parameters:

current - The Current object for the invocation.

Throws:

ServerError

areTablesEnabled

public boolean areTablesEnabled(Ice.Current __current)
                         throws ServerError

Description copied from interface: _SharedResourcesOperations

Returns true if a Tables service is active in the grid. If this value is false, then all calls to #ewTable or openTable will either fail or return null (possibly blocking while waiting for a service to startup)

Specified by:

areTablesEnabled in interface _SharedResourcesOperations

Parameters:

__current - The Current object for the invocation.

Throws:

ServerError

newTable

public TablePrx newTable(long repo,
                         java.lang.String path,
                         Ice.Current __current)
                  throws ServerError

Description copied from interface: _SharedResourcesOperations

Creates a new Format(""OMERO.tables"") file at the given path on the given repository. The returned Table proxy follows the same semantics as the openTable method.

Specified by:

newTable in interface _SharedResourcesOperations

__current - The Current object for the invocation.

Throws:

ServerError

openTable

public TablePrx openTable(OriginalFile file,
                          Ice.Current __current)
                   throws ServerError

Description copied from interface: _SharedResourcesOperations

Returns a Table instance or null. Table instances are not exclusively owned by the client and may throw an OptimisticLockException if background modifications take place. The file instance must be managed (i.e. have a non-null id) and be of the format ""OMERO.tables"". Use newTable() to create a new instance.

Specified by:

openTable in interface _SharedResourcesOperations

__current - The Current object for the invocation.

Throws:

ServerError

Waits up to seconds to acquire a slot in a processor which can handle the given job.

Specified by:

Throws:

ServerError

public void removeProcessor(ProcessorPrx proc,
                            Ice.Current __current)
                     throws ServerError
