Interface TermList

All Superinterfaces:

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

public interface TermList
extends OsidList

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

       
       
       while (tl.hasNext()) {
            Term term = tl.getNextTerm();
       }
       
                   
       
  

or

       
       
       while (tl.hasNext()) {
            Term[] terms = tl.getNextTerms(tl.available());
       }
