Constructor Detail

ConfigurationFileListIterator

public ConfigurationFileListIterator(AbstractConfigurationFile parent,
                                     ListIterator<AbstractEntry> delegate)

Constructor for ConfigurationFileListIterator

Parameters:

parent - parent used to check for valid entry types

delegate - ListIterator delegate

Method Detail

add

public void add(AbstractEntry entry)

Inserts the specified element into the List

Specified by:

add in interface ListIterator<AbstractEntry>

Parameters:

entry - element with which to replace the last element returned by next or previous

hasNext

public boolean hasNext()

Determines if there are more elements. (In other words, true if next would get an element rather than throwing an exception.)

Specified by:

hasNext in interface Iterator<AbstractEntry>

Specified by:

hasNext in interface ListIterator<AbstractEntry>

Returns:

true if this list iterator has more elements when traversing the list in the forward direction

hasPrevious

public boolean hasPrevious()

Determines if there is a previous element. (In other words, true if previous would get an element rather than throwing an exception.)

Specified by:

hasPrevious in interface ListIterator<AbstractEntry>

Returns:

true if this list iterator has more elements when traversing the list in the reverse direction

next

public AbstractEntry next()

Gets the next element in the List. (Note that alternating calls to next and previous will get the same element repeatedly.)

Specified by:

next in interface Iterator<AbstractEntry>

Specified by:

next in interface ListIterator<AbstractEntry>

Returns:

next element in the List

nextIndex

public int nextIndex()

Gets the index of the element that would be returned by a subsequent call to next. (Returns list size if the ListIterator is at the end of the List.)

Specified by:

nextIndex in interface ListIterator<AbstractEntry>

Returns:

index of the element that would be returned by a subsequent call to next

previous

public AbstractEntry previous()

Gets the previous element in the List. (Note that alternating calls to next and previous will get the same element repeatedly.)

Specified by:

previous in interface ListIterator<AbstractEntry>

Returns:

previous element in the List

previousIndex

public int previousIndex()

Gets the index of the element that would be returned by a subsequent call to previous. (Returns -1 if the ListIterator is at the beginning of the List.)

Specified by:

previousIndex in interface ListIterator<AbstractEntry>

Returns:

index of the element that would be returned by a subsequent call to previous

remove

public void remove()

Removes from the List the last element that was returned by next or previous. This call can only be made once per call to next or previous. It can be made only if ListIterator.add has not been called after the last call to next or previous.

Specified by:

remove in interface Iterator<AbstractEntry>

Specified by:

remove in interface ListIterator<AbstractEntry>

set

public void set(AbstractEntry entry)

Replaces the last element returned by next or previous with the specified element. This call can be made only if neither ListIterator.remove nor ListIterator.add have been called after the last call to next or previous.

Specified by:

set in interface ListIterator<AbstractEntry>

Parameters:

entry - element with which to replace the last element returned by next or previous
