Constructor Detail

WabitJoin

public WabitJoin(QueryCache query,
                 ca.sqlpower.query.SQLJoin delegate)

Constructs a WabitJoin that converts SQLJoin events to SPListener events.

Parameters:

query - The QueryCache this WabitJoin will be a part of. This is passed in to find the appropriate WabitItem objects for the left and right columns of the given SQLJoin. If new WabitItems are created here their UUIDs would not match the WabitItems in the QueryCache and be considered different object.

delegate - The SQLJoin to listen to.

Method Detail

firePropertyChangeEvent

protected void firePropertyChangeEvent(java.beans.PropertyChangeEvent evt)

cleanup

public ca.sqlpower.object.CleanupExceptions cleanup()

Description copied from class: AbstractWabitObject

Default cleanup method that does nothing. Override and implement this method if cleanup is necessary.

Specified by:

cleanup in interface ca.sqlpower.object.SPObject

Overrides:

cleanup in class AbstractWabitObject

getQuery

public QueryCache getQuery()

XXX The query may be equivalent to the parent. If this is the case the query variable should be merged with the parent.

getDelegate

public ca.sqlpower.query.SQLJoin getDelegate()

Returns the SQLJoin delegate of this object. XXX This method should be removed in the future to make its delegate a proper delegate.

removeChildImpl

protected boolean removeChildImpl(ca.sqlpower.object.SPObject child)

Specified by:

removeChildImpl in class ca.sqlpower.object.AbstractSPObject

allowsChildren

public boolean allowsChildren()

Specified by:

allowsChildren in interface ca.sqlpower.object.SPObject

childPositionOffset

public int childPositionOffset(java.lang.Class<? extends ca.sqlpower.object.SPObject> childType)

Specified by:

getChildren

public java.util.List<? extends WabitObject> getChildren()

Specified by:

getChildren in interface ca.sqlpower.object.SPObject

getDependencies

public void setRightColumnOuterJoin(boolean isOuterJoin)

Specified by:

setRightColumnOuterJoin in interface ca.sqlpower.query.Join

isRightColumnOuterJoin

public boolean isRightColumnOuterJoin()

Specified by:

isRightColumnOuterJoin in interface ca.sqlpower.query.Join

removeAllListeners

public void removeAllListeners()

This remove all the listeners inside this object's delegate to ensure that listeners do not remain attached to the join when it is removed. Used for deleting a join.

XXX This should be removed and objects adding listeners to a join should remove the joins appropriately when they are not needed.

Specified by:

removeAllListeners in interface ca.sqlpower.query.Join
