getServiceInterface

public java.lang.Class<? extends ome.api.ServiceInterface> getServiceInterface()

Specified by:

getServiceInterface in interface ome.system.SelfConfigurableService

contains

@Transactional(readOnly=false)
public boolean contains(java.lang.Object obj)

Description copied from interface: LocalQuery

Tests if an object is currently contained in the session.

Specified by:

contains in interface LocalQuery

evict

@Transactional(readOnly=false)
public void evict(java.lang.Object obj)

Description copied from interface: LocalQuery

Removes an object graph from the session. This allows for non-permanent, mutable calls on the graph.

Specified by:

evict in interface LocalQuery

clear

@Transactional(readOnly=false)
public void clear()

Specified by:

clear in interface LocalQuery

initialize

public void initialize(java.lang.Object obj)

Description copied from interface: LocalQuery

Uses the Hibernate static method initialize to prepare an object for shipping over the wire. It is better to do this in your queries.

Specified by:

initialize in interface LocalQuery

checkType

@Transactional(propagation=SUPPORTS)
public boolean checkType(java.lang.String type)

Description copied from interface: LocalQuery

Checks if a type has been mapped in Hibernate.

Specified by:

checkType in interface LocalQuery

Parameters:

type - String representation of a full-qualified Hibernate-mapped type.

Returns:

yes or no.

checkProperty

@Transactional(propagation=SUPPORTS)

                             java.lang.String property)

Description copied from interface: LocalQuery

Checks if a property is defined on a mapped Hibernate type.

Specified by:

checkProperty in interface LocalQuery

Parameters:

type - String representation of a full-qualified Hibernate-mapped type.

Returns:

yes or no.

isProbablyTimeout

public static boolean isProbablyTimeout(org.springframework.dao.DataAccessResourceFailureException exception)

Parameters:

exception - a wrapped query exception

Returns:

if the exception probably was caused by a timeout
