Properties:

• public virtual bool is_empty { get; }
  Specifies whether this collection is empty.
• public abstract bool read_only { get; }
  Specifies whether this collection can change - i.e. whether add, remove etc. are legal operations.
• public abstract Collection<G> read_only_view { owned get; }
  The read-only view of this collection.
• public abstract int size { get; }
  The number of items in this collection.

Static methods:

• public static Collection<G> empty<G> ()
  Returns an immutable empty collection.

Methods:

• public abstract bool add (G item)
  Adds an item to this collection. Must not be called on read-only collections.
• public virtual bool add_all (Collection<G> collection)
  Adds all items in the input collection to this collection.
• public virtual bool add_all_array (G[] array)
  Adds all items in the input array to this collection.
• public virtual bool add_all_iterator (Iterator<G> iter)
• public abstract void clear ()
  Removes all items from this collection. Must not be called on read-only collections.
• public abstract bool contains (G item)
  Determines whether this collection contains the specified item.
• public virtual bool contains_all (Collection<G> collection)
  Returns true it this collection contains all items as the input collection.
• public virtual bool contains_all_array (G[] array)
  Returns true it this collection contains all items as the input array.
• public virtual bool contains_all_iterator (Iterator<G> iter)
• public abstract bool remove (G item)
  Removes the first occurrence of an item from this collection. Must not be called on read-only collections.
• public virtual bool remove_all (Collection<G> collection)
  Removes the subset of items in this collection corresponding to the elements in the input collection. If there is several occurrences of the same value in this collection they are decremented of the number of occurrences in the input collection.
• public virtual bool remove_all_array (G[] array)
  Removes the subset of items in this collection corresponding to the elements in the input array. If there is several occurrences of the same value in this collection they are decremented of the number of occurrences in the input array.
• public virtual bool remove_all_iterator (Iterator<G> iter)
• public virtual bool retain_all (Collection<G> collection)
  Removes all items in this collection that are not contained in the input collection. In other words all common items of both collections are retained in this collection.
• public virtual G[] to_array ()
  Returns an array containing all of items from this collection.
