Class SimplexStream.Stack.StackIterator

java.lang.Object

edu.stanford.math.plex.SimplexStream.Stack.StackIterator

All Implemented Interfaces:

java.util.Iterator<Simplex>

Enclosing class:

SimplexStream.Stack

protected static class SimplexStream.Stack.StackIterator
extends java.lang.Object
implements java.util.Iterator<Simplex>

Instances provide Iterator for non-destructive iterating over Stack entries. That is, repeated iteration over a Stack instance is possible with multiple instances of this class.

Method Detail

hasNext

public boolean hasNext()

Returns true if the iterator has more simplices.

Specified by:

hasNext in interface java.util.Iterator<Simplex>

Returns:

true if the iterator has more simplices, else false.

next

public Simplex next()

Returns the next Simplex in the iteration of the Stack. Used in concert with the hasNext() method returns return each Simplex in the Stack exactly once. Does not have any side effects on the stream.

Specified by:

next in interface java.util.Iterator<Simplex>

Returns:

the next Simplex in the Stack.

Throws:

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

remove

public void remove()

Unsupported remove() operation.

Specified by:

remove in interface java.util.Iterator<Simplex>

Throws:

java.lang.UnsupportedOperationException
