Constructor Detail

SubResourceList

public SubResourceList(ResourceList collection,
                       int from,
                       int to)

Method Detail

get

public java.lang.Object get(int index)

Description copied from class: AbstractResourceList

item at the specified index.

Specified by:

get in interface java.util.List

Specified by:

get in class AbstractResourceList

Parameters:

index - index of item

Returns:

the item at the specified index.

size

public int size()

Description copied from class: AbstractResourceCollection

Returns the number of elements in this collection.

Specified by:

size in interface java.util.Collection

Specified by:

size in class AbstractResourceCollection

Returns:

Number of items, or Interger.MAX_VALUE

openIterator

protected java.util.Iterator openIterator()

Description copied from class: AbstractResourceList

Returns a quick iterator that uses get and size methods.

As with all resource collections it is assumed that the iterator will be closed after use.

Overrides:

openIterator in class AbstractResourceList

Returns:

an iterator over the elements in this list in proper sequence.

See Also:

AbstractResourceList.modCount

openIterator

public java.util.ListIterator openIterator(int index)

Overrides:

openIterator in class AbstractResourceList

closeIterator

protected void closeIterator(java.util.Iterator close)

Description copied from class: AbstractResourceCollection

Please override to cleanup after your own iterators, and any used resources.

As an example if the iterator was working off a File then the inputstream should be closed.

Subclass must call super.close( close ) to allow the list of open iterators to be adjusted.

Overrides:

closeIterator in class AbstractResourceList

clear

public void clear()

Description copied from class: AbstractResourceList

Removes all of the elements from this collection (optional operation).

This implementation calls removeRange(0, size()).

Note that this implementation throws an UnsupportedOperationException unless remove(int index) or removeRange(int fromIndex, int toIndex) is overridden.

Specified by:

clear in interface java.util.Collection

Overrides:

clear in class AbstractResourceList
