Class BasicEventList<E>

  • All Implemented Interfaces:
    EventList<E>, java.io.Serializable, java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>, java.util.RandomAccess
    public final class BasicEventList<E>
extends AbstractEventList<E>
implements java.io.Serializable, java.util.RandomAccess
    An EventList that wraps any simple List, such as ArrayList or LinkedList.

    Unlike most EventLists, this class is Serializable. When BasicEventList is serialized, all of its elements are serialized and all of its listeners that implement Serializable. Upon deserialization, the new copy uses a different lock than its source BasicEventList.

    • Method Detail

      • add

        public void add​(int index,
                E element)
        Inserts the specified element at the specified position in this list (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (adds one to their indices).
        Specified by:
        add in interface java.util.List<E>
        Overrides:
        add in class AbstractEventList<E>
        Parameters:
        index - index at which the specified element is to be inserted.
        element - element to be inserted.

      • add

        public boolean add​(E element)
        Appends the specified element to the end of this list (optional operation).

        Lists that support this operation may place limitations on what elements may be added to this list. In particular, some lists will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. List classes should clearly specify in their documentation any restrictions on what elements may be added.

        Specified by:
        add in interface java.util.Collection<E>
        Specified by:
        add in interface java.util.List<E>
        Overrides:
        add in class AbstractEventList<E>
        Parameters:
        element - element to be appended to this list.
        Returns:
        true (as per the general contract of the Collection.add method).

      • addAll

        public boolean addAll​(java.util.Collection<? extends E> collection)
        Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator (optional operation). The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)
        Specified by:
        addAll in interface java.util.Collection<E>
        Specified by:
        addAll in interface java.util.List<E>
        Overrides:
        addAll in class AbstractEventList<E>
        Parameters:
        collection - collection whose elements are to be added to this list.
        Returns:
        true if this list changed as a result of the call.
        See Also:
        AbstractEventList.add(Object)

      • addAll

        public boolean addAll​(int index,
                      java.util.Collection<? extends E> collection)
        Inserts all of the elements in the specified collection into this list at the specified position (optional operation). Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices). The new elements will appear in this list in the order that they are returned by the specified collection's iterator. The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)
        Specified by:
        addAll in interface java.util.List<E>
        Overrides:
        addAll in class AbstractEventList<E>
        Parameters:
        index - index at which to insert first element from the specified collection.
        collection - elements to be inserted into this list.
        Returns:
        true if this list changed as a result of the call.

      • remove

        public E remove​(int index)
        Removes the element at the specified position in this list (optional operation). Shifts any subsequent elements to the left (subtracts one from their indices). Returns the element that was removed from the list.
        Specified by:
        remove in interface java.util.List<E>
        Overrides:
        remove in class AbstractEventList<E>
        Parameters:
        index - the index of the element to removed.
        Returns:
        the element previously at the specified position.

      • remove

        public boolean remove​(java.lang.Object element)
        Removes the first occurrence in this list of the specified element (optional operation). If this list does not contain the element, it is unchanged. More formally, removes the element with the lowest index i such that (o==null ? get(i)==null : o.equals(get(i))) (if such an element exists).
        Specified by:
        remove in interface java.util.Collection<E>
        Specified by:
        remove in interface java.util.List<E>
        Overrides:
        remove in class AbstractEventList<E>
        Parameters:
        element - element to be removed from this list, if present.
        Returns:
        true if this list contained the specified element.

      • clear

        public void clear()

        clear in interface java.util.Collection<E>
        Specified by:
        clear in interface java.util.List<E>
