Interface RecordFilter

public interface RecordFilter

An interface defining a filter which examines a record to see if it matches (based on an application-defined criteria). The application implements the match() method to select records to be returned by the RecordEnumeration. Returns true if the candidate record is selected by the RecordFilter. This interface is used in the record store for searching or subsetting records. For example:

 RecordFilter f = new DateRecordFilter(); // class implements RecordFilter
 if (f.matches(recordStore.getRecord(theRecordID)) == true)
   DoSomethingUseful(theRecordID);
