Package ome.services.util

Helper classes to support OMERO service beans Instead of abstract classes, IOC methods and dependency injection is used to provide service interception for the Service (binary) bean classes.

Interface Summary

Interface	Description
Executor	Simple execution/work interface which can be used for internal tasks which need to have a full working implementation.
Executor.SqlWork	Work SPI to perform actions related to stateless sessions.
Executor.StatefulWork	In the case of a stateful work order, the bean itself needs to be associated with the sessionHandler and thread rather than the word instance itself.
Executor.Work<X>	Work SPI to perform actions within the server as if they were fully wrapped in our service logic.

Class Summary

Class	Description
BeanHelper	Helper for all bean implementations.
DBEnumCheck	Hook run by the context to guarantee that various enumerations are up to date.
DBMappedEnumCheck	When a new version of the OMERO server starts up check that the database includes an enumeration instance for every value mapped for code generation.
DBPatchCheck	Hook run by the context.
DBUnicodeUnitsCheck	Checks that the database contains correctly encoded enumerations for units of measure.
DBUserCheck	Hook run by the context.
EnsureEnum	Utility bean for ensuring that enumeration values do exist in the database.
ExecutionThread	Thread which can be started and will appropriately acquire a session, then use the Executor to complete its work.
Executor.Descriptive
Executor.Impl
Executor.SimpleSqlWork	Simple adapter which takes a String for Executor.Descriptive.description
Executor.SimpleWork	Simple adapter which takes a String for Executor.Descriptive.description
IceUtil	Methods for working with Ice.
JvmSettingsCheck	Hook run by the context which prints out JVM-related information, primarily Java version, max heap size and available processors.
ServerDirectoryCheck	Hook run by the context at startup to create needed directories for the server.
ServerVersionCheck	Hook run by the context.
ServiceHandler
SleepTimer	Provides a timer for having a thread sleep that prematurely awakens when the server is to shut down, so the sleeping does not keep the server running.
