Interface PathList

All Superinterfaces:

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

public interface PathList
extends OsidList

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

       
       
       while (pl.hasNext()) {
            Path path = pl.getNextPath();
       }
       
                   
       
  

or

       
       
       while (pl.hasNext()) {
            Path[] paths = pl.getNextPaths(pl.available());
       }

getNextPath

Path getNextPath()
                 throws OperationFailedException

Gets the next Path in this list.

Throws:

IllegalStateException - no more elements available in this list

OperationFailedException - unable to complete request

Compliance:

mandatory - This method must be implemented.

getNextPaths

Path[] getNextPaths(long n)
                    throws OperationFailedException

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

Parameters:

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

Returns:

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

Throws:

IllegalStateException - no more elements available in this list
