Class NativeEdgeIterator

java.lang.Object
  cage.NativeEdgeIterator

All Implemented Interfaces:

EdgeIterator, java.util.Iterator

public class NativeEdgeIterator
extends java.lang.Object
implements EdgeIterator

Returned by a NativeEmbeddableGraph as an iterator over its edges.

Constructor Summary

NativeEdgeIterator()

Method Summary

protected void	finalize() Lets the native code run its finalization first and then just call super.finalize().
boolean	hasNext() Returns true if the iteration has more edges.
java.lang.Object	next() Returns the next edge in the iteration.
int	nextEdge() Returns the next edge in the iteration.
void	remove() Throws UnsupportedOperationException because edges can't be removed.

Constructor Detail

NativeEdgeIterator

public NativeEdgeIterator()

Method Detail

hasNext

public boolean hasNext()

Returns true if the iteration has more edges. (In other words, returns true if next would return an element rather than throwing an exception.)

Specified by:

hasNext in interface java.util.Iterator

Returns:

true if the iterator has more elements.

next

public java.lang.Object next()
                      throws java.util.NoSuchElementException

Returns the next edge in the iteration. Calling this method repeatedly until the hasNext() method returns false will return each element in the underlying collection exactly once.

Specified by:

next in interface java.util.Iterator

Returns:

the next edge in the iteration as an MutableInteger.

Throws:

java.util.NoSuchElementException - iteration has no more elements.

nextEdge

public int nextEdge()
             throws java.util.NoSuchElementException

Returns the next edge in the iteration. Calling this method repeatedly until the hasNext() method returns false will return each element in the underlying collection exactly once.

Specified by:

nextEdge in interface EdgeIterator

Returns:

the next edge in the iteration as an int.

Throws:

java.util.NoSuchElementException - iteration has no more elements.

remove

public void remove()
            throws java.lang.UnsupportedOperationException

Throws UnsupportedOperationException because edges can't be removed.

Specified by:

remove in interface java.util.Iterator

Throws:

java.lang.UnsupportedOperationException - if the remove operation is not supported by this Iterator.

finalize

protected void finalize()
                 throws java.lang.Throwable

Lets the native code run its finalization first and then just call super.finalize().

Overrides:

finalize in class java.lang.Object

Throws:

java.lang.Throwable
