org.springframework.transaction.support .ResourceHolderSupport

All known Subclasses:   org.springframework.orm.toplink .SessionHolder,  org.springframework.jca.cci.connection .ConnectionHolder,  org.springframework.orm.hibernate3 .SessionHolder,  org.springframework.orm.jdo .PersistenceManagerHolder,  org.springframework.jms.connection .JmsResourceHolder,  org.springframework.jdbc.datasource .ConnectionHolder,  org.springframework.orm.jpa .EntityManagerHolder,
ResourceHolderSupport
abstract public class ResourceHolderSupport (Code)
Convenient base class for resource holders.
Features rollback-only support for nested transactions. Can expire after a certain number of seconds or milliseconds, to determine transactional timeouts.

See Also:   org.springframework.jdbc.datasource.DataSourceUtils.applyTransactionTimeout

Method Summary
public void clear()
     Clear the transactional state of this resource holder.
public Date getDeadline()
     Return the expiration deadline of this object.
public long getTimeToLiveInMillis()
     Return the time to live for this object in milliseconds.
public int getTimeToLiveInSeconds()
     Return the time to live for this object in seconds. Rounds up eagerly, e.g.
public boolean hasTimeout()
     Return whether this object has an associated timeout.
public boolean isOpen()
     Return whether there are still open references to this holder.
public boolean isRollbackOnly()
     Return whether the resource transaction is marked as rollback-only.
public boolean isSynchronizedWithTransaction()
     Return whether the resource is synchronized with a transaction.
public void released()
     Decrease the reference count by one because the holder has been released (i.e.
public void requested()
     Increase the reference count by one because the holder has been requested (i.e.
public void reset()
     Reset this resource holder - transactional state as well as reference count.
public void setRollbackOnly()
     Mark the resource transaction as rollback-only.
public void setSynchronizedWithTransaction(boolean synchronizedWithTransaction)
     Mark the resource as synchronized with a transaction.
public void setTimeoutInMillis(long millis)
     Set the timeout for this object in milliseconds.
public void setTimeoutInSeconds(int seconds)
     Set the timeout for this object in seconds.
