SourcePriorityComparator

public SourcePriorityComparator(DataTracker dataTracker,
                                java.lang.Class<? extends InterMineObject> clazz,
                                java.lang.String fieldName,
                                Source def,
                                InterMineObject defObj,
                                IntPresentSet dbIdsStored,
                                IntegrationWriterAbstractImpl iw,
                                Source source,
                                Source skelSource,
                                PriorityConfig priorityConfig)

Constructs a new Comparator for comparing objects for priority for a given field.

Parameters:

dataTracker - the data tracker

clazz - the Class of the resulting object

fieldName - the fieldName the comparison is for

def - the default Source

defObj - a InterMineObject that came from a data source, not from the destination objectstore, and should be associated with the default source

dbIdsStored - the set of IDs stored in this dataloader run - improves error messages

iw - the IntegrationWriter creating this comparator

source - the main source, as passed to iw.store

skelSource - the skeleton source, as passed to iw.store

priorityConfig - a PriorityConfig object for the target Model

Method Detail

compare

public int compare(InterMineObject o1,
                   InterMineObject o2)

Compares two objects. These objects must both be InterMineObjects.

Specified by:

compare in interface java.util.Comparator<InterMineObject>

Parameters:

o1 - the first object

o2 - the second object

Returns:

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second

Throws:

java.lang.ClassCastException - if either of the two objects is not a InterMineObject

java.lang.RuntimeException - if an error occurs in the underlying data tracking objectstore
