Interface LogEntryList

All Superinterfaces:

java.lang.AutoCloseable, java.io.Closeable, OsidList

public interface LogEntryList
extends OsidList

Like all OsidLists, LogEntryList provides a means for accessing LogEntry elements sequentially either one at a time or many at a time. Examples:

       
       
       while (lel.hasNext()) {
            LogEntry entry = lel.getNextLogEntry();
       }
       
                   
       
  

or

       
       
       while (lel.hasNext()) {
            LogEntry[] entries = lel.getNextLogEntries(lel.available());
       }
