Method Detail

hasNext

public boolean hasNext()

Returns true if there are more edges in this iterator.

Specified by:

hasNext in interface EdgeNodeIterator

next

public void next()

Advances to the next edge in the iterator.

Specified by:

next in interface EdgeNodeIterator

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 EdgeNodeIterator

Throws:

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

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

check

private void check()

fromNode

public java.lang.Object fromNode()

Returns the node that his edge begins at.

Specified by:

fromNode in interface EdgeNodeIterator

Throws:

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

fromIndex

public int fromIndex()

Description copied from interface: IndexedEdgeNodeIterator

Returns the index of the node that his edge begins at.

Specified by:

fromIndex in interface IndexedEdgeNodeIterator

toNode

public java.lang.Object toNode()

Returns the node that this edge reaches.

Specified by:

toNode in interface EdgeNodeIterator

Throws:

java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

toIndex

public int toIndex()

Description copied from interface: IndexedEdgeNodeIterator

Returns the index of the node that this edge reaches.

Specified by:

toIndex in interface IndexedEdgeNodeIterator

edge
