Method Details

getXAResourceHolderStatesForGtrid

public Map<Uid,XAResourceHolderState> getXAResourceHolderStatesForGtrid(Uid gtrid)

Description copied from interface: XAResourceHolder

Get all the XAResourceHolderStates of this wrapped resource for a specific GTRID.

The returned Map is guaranteed to return states in order they were added when its values are iterated.

Specified by:

getXAResourceHolderStatesForGtrid in interface XAResourceHolder

Parameters:

gtrid - the GTRID of the transaction state to add.

Returns:

the XAResourceHolderState.

putXAResourceHolderState

public void putXAResourceHolderState(BitronixXid xid,
 XAResourceHolderState xaResourceHolderState)

Description copied from interface: XAResourceHolder

Add a XAResourceHolderState of this wrapped resource.

Specified by:

putXAResourceHolderState in interface XAResourceHolder

Parameters:

xid - the Xid of the transaction state to add.

xaResourceHolderState - the XAResourceHolderState to set.

removeXAResourceHolderState

public void removeXAResourceHolderState(BitronixXid xid)

Description copied from interface: XAResourceHolder

Remove all states related to a specific Xid from this wrapped resource.

Specified by:

removeXAResourceHolderState in interface XAResourceHolder

Parameters:

xid - the Xid of the transaction state to remove.

hasStateForXAResource

public boolean hasStateForXAResource(XAResourceHolder xaResourceHolder)

Description copied from interface: XAResourceHolder

Check if this XAResourceHolder contains a state for a specific XAResourceHolder. In other words: has the XAResourceHolder's XAResource been enlisted in some transaction ?

Specified by:

hasStateForXAResource in interface XAResourceHolder

Parameters:

xaResourceHolder - the XAResourceHolder to look for.

Returns:

true if the XAResourceHolder is enlisted in some transaction, false otherwise.

isParticipatingInActiveGlobalTransaction

public boolean isParticipatingInActiveGlobalTransaction()

If this method returns false, then local transaction calls like Connection.commit() can be made.

Returns:

true if start() has been successfully called but not end() yet and the transaction is not suspended.

getXAResourceHolderStateGtrids

public Set<String> getXAResourceHolderStateGtrids()

Simple helper method which returns a set of GTRIDs of transactions in which this resource is enlisted. Useful for monitoring.

Returns:

a set of String-encoded GTRIDs of transactions in which this resource is enlisted.
