ProjectEntityWithIDContainer

public ProjectEntityWithIDContainer(UniqueIdObjectSequenceProvider projectFile)

Constructor.

Parameters:

projectFile - parent project

Method Detail

renumberIDs

public void renumberIDs()

This method can be called to ensure that the IDs of all entities are sequential, and start from an appropriate point. If entities are added to and removed from this list, then the project is loaded into Microsoft project, if the ID values have gaps in the sequence, there will be blank rows shown.

Parameters:

id - ID to remove

mapID

public void mapID(Integer id,
                  T entity)

Add an ID to instance mapping.
