Summary

Compares the item with another

Pascal

 functionCompare(constADataObj: TJvCustomInspectorData; constItem: TJvCustomInspectorRegItem): Integer; virtual;

Parameters

Parameters	Description
const ADataObj: TJvCustomInspectorData	Data layer instance use for comparison
const Item: TJvCustomInspectorRegItem	Registration item to compare with

Return Value

If the specified item is a better match than this item, the negated match value is returned, otherwise the match value of this item is returned. If the items could not be compared, not the match value will be returned but the match percentages using the same rules as for the match value (ie. a negative number means the specified item is a better match, a positive number means this item is the better match).

Description

Compare compares the item with the specified item. The registration item uses two compare methods, Compare and CompareTo, which work in a similar way as Assign and AssignTo: if Compare doesn't know how to compare the two items, It swaps the items and calls CompareTo.
The Compare method in TJvCustomInspectorRegItem will call the specified items' CompareTo method with itself as a parameter. The result of this call will be negated (because the order of the items was swapped) and returned.
