Constructor Detail

JdapiModuleListIterator

public JdapiModuleListIterator(java.util.Vector list)

Constructor.

Parameters:

list - List of modules

JdapiModuleListIterator

public JdapiModuleListIterator(JdapiModuleListIterator other)

Copy constructor.

Parameters:

other - Iterator to copy

Method Detail

toString

public java.lang.String toString()

Get a string representation of the current state of the object.

Overrides:

toString in class java.lang.Object

Returns:

String representation of the current state

clone

public java.lang.Object clone()

Creates a copy of the iterator at the current position.

Overrides:

clone in class java.lang.Object

Returns:

FormsModuleListIterator on the same list at the current position

goLast

public void goLast()

Moves the iterator to the end of the list. Useful if you want to step backwards through a list.

Specified by:

goLast in interface JdapiIterator

goStart

public void goStart()

Moves the iterator to the start of the list.

Specified by:

goStart in interface JdapiIterator

hasNext

public boolean hasNext()

Returns true if the iteration has more elements (JDK1.2 iterator style).

Specified by:

hasNext in interface java.util.Iterator

Specified by:

hasNext in interface JdapiIterator

Returns:

If the iteration has more elements

hasPrevious

public boolean hasPrevious()

Returns true if the iteration has previous elements (JDK1.2 list iterator style).

Specified by:

hasPrevious in interface JdapiIterator

Returns:

If the iteration has previous elements

next

public java.lang.Object next()

Gets the next object (JDK1.2 iterator style).

Specified by:

next in interface java.util.Iterator

Specified by:

next in interface JdapiIterator

Returns:

The next object, null if there are none

previous

public java.lang.Object previous()

Gets the previous object (JDK1.2 list iterator style).

Specified by:

previous in interface JdapiIterator

Returns:

The previous object, null if there are none

remove

public void remove()
            throws JdapiException

Removes the current object from the iteration. You may not call this method twice on the same object in the iteration. This is the method you should use if you want to remove objects from within an iteration and continue to go through the iteration. If you destroy an object in the iteration any other way, the iterator will probably fail.

If the iterator is not positioned at the first element of the list, it will position itself there before doing the remove. This allows you to write code like:

   while(iter.hasNext()) {
     iter.remove();
   }
 

Specified by:

remove in interface java.util.Iterator

Specified by:

remove in interface JdapiIterator

Throws:

JdapiException
