Constructor Detail

ProjectContainer

public ProjectContainer()

Method Detail

getStartYear

public int getStartYear()

isBlockEvents

public boolean isBlockEvents()

setBlockEvents

public void setBlockEvents(boolean blockEvents)

setStartYear

public void setStartYear(int pStartYear)

Sets a new start year. All projects will adjusted regarding start and end, feature availability is updated

Parameters:

pStartYear - Start year to set (e. g. 2000 for year 2000. Easy, eh?)

removeGhostRelations

public int removeGhostRelations()

Change all existing ghost relations to 'real' relations

Returns:

Number of changed relations

commitGhostRelations

public int commitGhostRelations()

Change all existing ghost relations to 'real' relations

Returns:

Number of changed relations

fixTimings

public void fixTimings()

Fixes timings for all projects in container.

ProjectItem#fixTiming(int,boolean)

beginBatchUpdate

public void beginBatchUpdate()

Starts a batch update. This is useful to change multiple objetcs with updating the view on every change. All events during an batch update are queued and will be issued after the change succeeded.

NoteYou have to call endBatchUpdate() to finish tha update correctly. So you shold enclose your update operations in a try..finally block.
