Constructor Detail

FlatIterator

public FlatIterator(Traversable parent)

Creates a new iterator.

Method Detail

add

public void add(Traversable t)

Adds an object after the last object that was returned by next or previous.

Parameters:

t - The object to add.

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.

hasPrevious

public boolean hasPrevious()

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.

previous

public java.lang.Object previous()

remove

public void remove()

Removes the last object that was returned by next or previous.

Specified by:

remove in interface java.util.Iterator

Overrides:

remove in class IRIterator

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

getList

public java.util.List 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
