Constructor Detail

AbstractListIterator

public AbstractListIterator()

Default constructor (for base class invocation). Does nothing. Remind Sun (jdk-comments@java.sun.com) that automatically implemented default constructors are a silly thing.

Method Detail

get

public abstract Object get()

Description copied from class: AbstractIterator

Returns the value currently being considered by the AbstractIterator. This method is required by neither Iterator nor Enumeration. This method should be implemented, however, to provide better support for for-loops.

Overrides:

get in class AbstractIterator

Following copied from class: structure.AbstractIterator

Returns:

the next value to be considered in iterator

remove

public void remove()

Description copied from class: AbstractIterator

If implemented, removes the currently visited value from the structure. remove should not be called unless it is overridden.

Specified by:

remove in interface ListIterator

Overrides:

remove in class AbstractIterator

set

public void set(Object o)

Specified by:

set in interface ListIterator

add

public void add(Object o)

Specified by:

add in interface ListIterator
