Interface EngineNodeList

All Superinterfaces:

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

public interface EngineNodeList
extends OsidList

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

       
       
       while (enl.hasNext()) {
            EngineNode node = enl.getNextEngineNode();
       }
       
                   
       
  

or

       
       
       while (enl.hasNext()) {
            EngineNode[] nodes = enl.getNextEngineNodes(enl.available());
       }

Method Detail

getNextEngineNode

EngineNode getNextEngineNode()
                             throws OperationFailedException

Gets the next EngineNode in this list.

Returns:

the next EngineNode in this list. The hasNext() method should be used to test that a next EngineNode is available before calling this method.

Throws:

IllegalStateException - no more elements available in this list

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

getNextEngineNodes

EngineNode[] getNextEngineNodes(long n)
                                throws OperationFailedException

Gets the next set of EngineNode elements in this list. The specified amount must be less than or equal to the return from available().

Parameters:

n - the number of EngineNode elements requested which must be less than or equal to available()

Returns:

an array of EngineNode elements. The length of the array is less than or equal to the number specified.

Throws:

IllegalStateException - no more elements available in this list

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.
