Name
javax.microedition.rms.RecordComparator
Synopsis
This interface defines several constants and the compare( )
method that can be used to compare two records to check
if they match, or what their relative sort order is. A class that
needs to compare two candidate records should implement this
interface by providing an implementation for the compare( )
method. The constants defined in this interface have the
following meaning in terms of sort order:
-
EQUIVALENT
The two records are the same but not necessarily identical.
-
FOLLOWS
Rec1 follows rec2.
-
PRECEDES
Rec1 precedes rec2.
The compare( )
method returns
EQUIVALENT
if rec1 and rec2 are equivalent in
terms of sort order, PRECEDES
if rec1 precedes
rec2, or FOLLOWS
if rec1 follows rec2.
