Constructor Detail

DepthFirstIterator

public DepthFirstIterator(Traversable init)

Creates a new iterator.

Parameters:

init - The first object to visit.

Method Detail

hasNext

public boolean hasNext()

Description copied from class: IRIterator

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

Specified by:

hasNext in interface java.util.Iterator

Specified by:

hasNext in class IRIterator

Returns:

true if the iterator has more elements.

next

public java.lang.Object next()

Description copied from class: IRIterator

Returns the next element in the iteration.

Specified by:

next in interface java.util.Iterator

Specified by:

next in class IRIterator

Returns:

the next element in the iteration.

pruneOn

public void pruneOn(java.lang.Class c)

getList

public java.util.LinkedList getList(java.lang.Class c)

Returns a linked list of objects of Class c in the IR

getSet

public java.util.Set getSet(java.lang.Class c)

Returns a set of objects of Class c in the IR

reset

public void reset()

Description copied from class: IRIterator

Moves the iterator back to the beginning of the sequence.

Specified by:

reset in class IRIterator
