public Class NonNullElementWrapperList<E>

Overrides java.util.AbstractList.add.

Implements java.util.List.add.

Doc from java.util.AbstractList.add.

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).

@Override

Overrides java.util.AbstractList.clear.

Implements java.util.List.clear, java.util.Collection.clear.

Doc from java.util.AbstractList.clear.

Removes all of the elements from this list (optional operation). The list will be empty after this call returns.

@Override

Overrides java.util.AbstractCollection.contains.

Implements java.util.List.contains, java.util.Collection.contains.

Doc from java.util.List.contains.

Returns true if this list contains the specified element. More formally, returns true if and only if this list contains at least one element e such that Objects.equals(o, e).

Annotations

@Override

Overrides java.util.AbstractList.equals.

Implements java.util.List.equals, java.util.Collection.equals.

Doc from java.util.AbstractList.equals.

Compares the specified object with this list for equality. Returns true if and only if the specified object is also a list, both lists have the same size, and all corresponding pairs of elements in the two lists are equal. (Two elements e1 and e2 are equal if (e1==null ? e2==null : e1.equals(e2)).) In other words, two lists are defined to be equal if they contain the same elements in the same order.

@Override

Implements abstract java.util.AbstractList.get.

Implements java.util.List.get.

Doc from java.util.AbstractList.get.

Returns the element at the specified position in this list.

Annotations

@Override

Overrides java.util.AbstractList.hashCode.

Implements java.util.List.hashCode, java.util.Collection.hashCode.

Doc from java.util.AbstractList.hashCode.

Returns the hash code value for this list.

Annotations

@Override

Overrides java.util.AbstractList.indexOf.

Implements java.util.List.indexOf.

Doc from java.util.AbstractList.indexOf.

Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element. More formally, returns the lowest index i such that Objects.equals(o, get(i)), or -1 if there is no such index.

Annotations

@Override

Overrides java.util.AbstractList.lastIndexOf.

Implements java.util.List.lastIndexOf.

Doc from java.util.AbstractList.lastIndexOf.

Returns the index of the last occurrence of the specified element in this list, or -1 if this list does not contain the element. More formally, returns the highest index i such that Objects.equals(o, get(i)), or -1 if there is no such index.

Annotations

@Override

Overrides java.util.AbstractList.remove.

Implements java.util.List.remove.

Doc from java.util.AbstractList.remove.

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.

Annotations

@Override

Overrides java.util.AbstractCollection.remove.

Implements java.util.List.remove, java.util.Collection.remove.

Doc from java.util.List.remove.

Removes the first occurrence of the specified element from this list, if it is present (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 Objects.equals(o, get(i)) (if such an element exists). Returns true if this list contained the specified element (or equivalently, if this list changed as a result of the call).

Annotations

@SuppressWarnings:UngroupedOverloads

@Override

Overrides java.util.AbstractCollection.removeAll.

Implements java.util.List.removeAll, java.util.Collection.removeAll.

Doc from java.util.List.removeAll.

Removes from this list all of its elements that are contained in the specified collection (optional operation).

Annotations

@Override

Overrides java.util.AbstractCollection.retainAll.

Implements java.util.List.retainAll, java.util.Collection.retainAll.

Doc from java.util.List.retainAll.

Retains only the elements in this list that are contained in the specified collection (optional operation). In other words, removes from this list all of its elements that are not contained in the specified collection.

Annotations

@Override

Overrides java.util.AbstractList.set.

Implements java.util.List.set.

Doc from java.util.AbstractList.set.

Replaces the element at the specified position in this list with the specified element (optional operation).

Annotations

@Override

Implements abstract java.util.AbstractCollection.size.

Implements java.util.List.size, java.util.Collection.size.

Doc from java.util.List.size.

Returns the number of elements in this list. If this list contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Annotations

@Override

Overrides java.util.AbstractCollection.toArray.

Implements java.util.List.toArray, java.util.Collection.toArray.

Doc from java.util.List.toArray.

Returns an array containing all of the elements in this list in proper sequence (from first to last element).

The returned array will be "safe" in that no references to it are maintained by this list. (In other words, this method must allocate a new array even if this list is backed by an array). The caller is thus free to modify the returned array.

This method acts as bridge between array-based and collection-based APIs.

Annotations

@Override

Overrides java.util.AbstractCollection.toArray.

Implements java.util.List.toArray, java.util.Collection.toArray.

Doc from java.util.List.toArray.

Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of the returned array is that of the specified array. If the list fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this list.

If the list fits in the specified array with room to spare (i.e., the array has more elements than the list), the element in the array immediately following the end of the list is set to null. (This is useful in determining the length of the list only if the caller knows that the list does not contain any null elements.)

Like the toArray() method, this method acts as bridge between array-based and collection-based APIs. Further, this method allows precise control over the runtime type of the output array, and may, under certain circumstances, be used to save allocation costs.

Suppose x is a list known to contain only strings. The following code can be used to dump the list into a newly allocated array of String:

String[] y = x.toArray(new String[0]);
