Class UnmodifiableListIteratorSTL<T>

java.lang.Object

generic.stl.ListIterator<T>

generic.stl.UnmodifiableListIteratorSTL<T>

All Implemented Interfaces:

IteratorSTL<T>

public class UnmodifiableListIteratorSTL<T>
extends ListIterator<T>

This wrapper class is used to detect cases where code is modifying iterators that shouldn't change.

Constructor Detail

UnmodifiableListIteratorSTL

public UnmodifiableListIteratorSTL(ListIterator<T> iterator)

Method Detail

assign

public void assign(IteratorSTL<T> otherIterator)

Description copied from interface: IteratorSTL

'Assigns' this iterator to be equivalent to the given iterator. This is equivalent to C++'s '=' overloading mechanism

Specified by:

assign in interface IteratorSTL<T>

Overrides:

assign in class ListIterator<T>

Parameters:

otherIterator - The iterator to copy

decrement

public IteratorSTL<T> decrement()

Description copied from interface: IteratorSTL

Devance the iterator to the previous position. This method is only supported in bidirectional iterators.

Specified by:

decrement in interface IteratorSTL<T>

Overrides:

decrement in class ListIterator<T>

Returns:

a reference to the iterator itself

decrement

public IteratorSTL<T> decrement(int n)

Description copied from interface: IteratorSTL

Devances the iterator n positions.

Specified by:

decrement in interface IteratorSTL<T>

Overrides:

decrement in class ListIterator<T>

Returns:

a reference to the iterator itself

delete

public void delete()

delete

public void delete(int count)

increment

public IteratorSTL<T> increment()

Description copied from interface: IteratorSTL

Advances the iterator to the next position.

Specified by:

increment in interface IteratorSTL<T>

Overrides:

increment in class ListIterator<T>

Returns:

a reference to the iterator itself

increment

public IteratorSTL<T> increment(int n)

Description copied from interface: IteratorSTL

Advances the iterator n positions.

Specified by:

increment in interface IteratorSTL<T>

Overrides:

increment in class ListIterator<T>

Returns:

a reference to the iterator itself

insert

public void insert(T value)

Description copied from interface: IteratorSTL

Inserts the given value at the current position (the current value will be pushed to the next value). The iterator will be positioned on the new value.

Specified by:

insert in interface IteratorSTL<T>

Overrides:

insert in class ListIterator<T>

Parameters:

value - the value to insert into the collection.

set

public void set(java.lang.Object value)

Description copied from interface: IteratorSTL

Sets the current value of the iterator to the given value.

Specified by:

set in interface IteratorSTL<T>

Overrides:

set in class ListIterator<T>

Parameters:

value - the value to set at the iterator position
