Interface AwardRequirementList

All Superinterfaces:

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

public interface AwardRequirementList
extends OsidList

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

       
       
       while (arl.hasNext()) {
            AwardRequirement req = arl.getNextAwardRequirement();
       }
       
                   
       
  

or

       
       
       while (arl.hasNext()) {
            AwardRequirement[] reqs = arl.getNextAwardRequirements(arl.available());
       }
