Class ProxiedList<E>

java.lang.Object

de.larssh.utils.collection.ProxiedCollection<E>

de.larssh.utils.collection.ProxiedList<E>

Type Parameters:

E - the type of elements in this list

All Implemented Interfaces:

Iterable<E>, Collection<E>, List<E>

Direct Known Subclasses:

Csv, CsvRow

public abstract class ProxiedList<E>
extends ProxiedCollection<E>
implements List<E>

An abstract List implementation pointing to a given list object.

Therefore it allows implementing lists based on invisible list types, such as Collections.unmodifiableList(List) or Collections.synchronizedList(List).

ProxiedList

protected ProxiedList(List<E> list)

An abstract List implementation pointing to list.

Therefore it allows implementing lists based on invisible list types, such as Collections.unmodifiableList(List) or Collections.synchronizedList(List).

Parameters:

list - the list to proxy

Method Detail

add

public void add(int index,
                @Nullable
                E element)

Specified by:

add in interface List<E>

addAll

public boolean addAll(int index,
                      @Nullable
                      Collection<? extends E> collection)

Specified by:

addAll in interface List<E>

get

@Nullable
public E get(int index)

Specified by:

get in interface List<E>

getWrappedIfModifiable

protected List<E> getWrappedIfModifiable()

Verifies if this object is modifiable and either returns the wrapped collection or throws an appropriate exception.

Overrides:

getWrappedIfModifiable in class ProxiedCollection<E>

Returns:

the wrapped collection if this object is modifiable

getWrappedForRead

protected List<E> getWrappedForRead()

Returns the wrapped collection without verifying if modifying it is prohibited.

Overrides:

getWrappedForRead in class ProxiedCollection<E>

Returns:

the wrapped collection

Specified by:

listIterator in interface List<E>

listIterator

public ListIterator<E> listIterator(int index)

Specified by:

listIterator in interface List<E>

remove

@Nullable
public E remove(int index)

Specified by:

remove in interface List<E>

set

@Nullable
