Interface BinNodeList

All Superinterfaces:

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

public interface BinNodeList
extends OsidList

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

       
       
       while (bnl.hasNext()) {
            BinNode node = bnl.getNextBinNode();
       }
       
                   
       
  

or

       
       
       while (bnl.hasNext()) {
            BinNode[] nodes = bnl.getNextBinNodes(bnl.available());
       }

Method Detail

getNextBinNode

BinNode getNextBinNode()
                       throws OperationFailedException

Gets the next BinNode in this list.

Returns:

the next BinNode in this list. The hasNext() method should be used to test that a next BinNode 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.

getNextBinNodes

BinNode[] getNextBinNodes(long n)
                          throws OperationFailedException

Gets the next set of BinNode elements in this list which must be less than or equal to the return from available().

Parameters:

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

Returns:

an array of BinNode 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.
