Class JdapiObjectChildIterator

java.lang.Object

oracle.forms.jdapi.JdapiObjectChildIterator

All Implemented Interfaces:

java.util.Iterator, JdapiIterator

class JdapiObjectChildIterator
extends java.lang.Object
implements JdapiIterator

This class implements an iterator for Jdapi owned objects

Note that the iterator will reflect a snapshot of the state of the passed object's children at the time the method was called, so the Iterator will become incorrect if the objects children are subsequently changed. This, however, prevents a potential error condition such as an infinite iteration from arising.

Method Detail

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.

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.

Specified by:

hasPrevious in interface JdapiIterator

Returns:

If the iteration has previous elements

next

public java.lang.Object next()

Gets the next object.

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.

Specified by:

previous in interface JdapiIterator

Returns:

The previous object, null if there are none

remove

public void remove()

Removes the current object from the iteration. Note that this method is NOT implemented for this iterator.
