Method Detail

addAllOf

public void addAllOf(Collection<T> collection)

Appends all of the elements of the specified Collection to the receiver.

Throws:

ClassCastException - if an element in the collection is not of the same parameter type of the receiver.

beforeInsertAllOf

public void beforeInsertAllOf(int index,
                     Collection<T> collection)

Inserts all elements of the specified collection before the specified position into the receiver. Shifts the element currently at that position (if any) and any subsequent elements to the right (increases their indices).

Parameters:

index - index before which to insert first element from the specified collection.

collection - the collection to be inserted

Throws:

ClassCastException - if an element in the collection is not of the same parameter type of the receiver.

IndexOutOfBoundsException - if index < 0 || index > size().

replaceFromWith

public abstract void replaceFromWith(int from,
                   Collection<T> other)

Replaces the part of the receiver starting at from (inclusive) with all the elements of the specified collection. Does not alter the size of the receiver. Replaces exactly Math.max(0,Math.min(size()-from, other.size())) elements.

Parameters:

from - the index at which to copy the first element from the specified collection.

other - Collection to replace part of the receiver

Throws:

IndexOutOfBoundsException - if index < 0 || index >= size().
