Method Detail

hasNext

public boolean hasNext()

Returns true if there are more edges in this iterator.

Specified by:

hasNext in interface java.util.Iterator

next

public java.lang.Object next()

Advances to the next edge in the iterator.

Specified by:

next in interface java.util.Iterator

Throws:

java.util.NoSuchElementException - if the iterator has nothing left.

remove

public void remove()

Removes the current edge from the digraph.

Specified by:

remove in interface java.util.Iterator

Throws:

java.lang.UnsupportedOperationException - if the digraph is immutable.
