Description copied from interface:MutableCollectionThis method allows mutable and fixed size collections the ability to add elements to their existing elements. In order to support fixed size a new instance of a collection would have to be returned taking the elements of the original collection and appending the new element to form the new collection. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:MutableCollection<String> list = list.with("1"); list = list.with("2"); return list;In the case ofFixedSizeCollectiona new instance of MutableCollection will be returned by with, and any variables that previously referenced the original collection will need to be redirected to reference the new instance. For other MutableCollection types you will replace the reference to collection with the same collection, since the instance will return "this" after calling add on itself.- Specified by:

Description copied from interface:MutableCollectionThis method allows mutable and fixed size collections the ability to remove elements from their existing elements. In order to support fixed size a new instance of a collection would have to be returned containing the elements that would be left from the original collection after calling remove. In the case of mutable collections, the original collection is modified, and is returned. In order to use this method properly with mutable and fixed size collections the following approach must be taken:MutableCollection<String> list = list.without("1"); list = list.without("2"); return list;In the case ofFixedSizeCollectiona new instance of MutableCollection will be returned by without, and any variables that previously referenced the original collection will need to be redirected to reference the new instance.

In the case of mutable collections, the original collection is modified, and is returned.

asSynchronized
Description copied from interface:MutableCollectionReturns a synchronized wrapper backed by this collection. This is the equivalent of usingCollections.synchronizedCollection(this)only with a return type that supports the full iteration protocols available onMutableCollection. The preferred way of iterating over a synchronized collection is to use the internal iteration methods which are properly synchronized internally.MutableCollection synchedCollection = collection.asSynchronized(); ... synchedCollection.forEach(each -> ... ); synchedCollection.select(each -> ... ); synchedCollection.collect(each -> ... );If you want to iterate using an imperative style, you must protect external iterators using a synchronized block. This includes explicit iterators as well as JDK 5 style for loops.- Specified by:

newEmpty
Description copied from interface:MutableCollectionCreates a new empty mutable version of the same collection type. For example, if this instance is a FastList, this method will return a new empty FastList. If the class of this instance is immutable or fixed size (i.e. SingletonList) then a mutable alternative to the class will be provided.- Specified by:
