C# Class Axiom.SceneManagers.Bsp.Collections.Map

Map class, a little different from the Axiom.Collections.Map class

A map allows multiple values per key, unlike the Hashtable which only allows unique keys and only a single value per key. Multiple values assigned to the same key are placed in a "bucket", which in this case is an ArrayList.

An example of values in a map would look like this: Key Value "a" "Alan" "a" "Adam" "b" "Brien" "c" "Chris" "c" "Carl" etc

Currently, enumeration is the only way to iterate through the values, which is more pratical in terms of how the Map works internally anyway. Intial testing showed that inserting and iterating through 100,000 items, the Inserts took ~260ms and a full enumeration of them all (with unboxing of the value type stored in the map) took between 16-30ms.

Public Methods

Method	Description
Clear ( ) : void	Clears this map of all contained objects.
Clear ( object key ) : void	Clears the bucket with given key.
Count ( object key ) : int	Gets the count of objects mapped to the specified key.
Find ( object key ) : IEnumerator	Given a key, Find will return an IEnumerator that allows you to iterate over all items in the bucket associated with the key.
FindBucket ( object key ) : IList
FindFirst ( object key ) : object	Given a key, FindFirst will return the first item in the bucket associated with the key.
GetBucketEnumerator ( ) : IEnumerator	Gets an appropriate enumerator for the map, customized to go through each key in the map and return a Pair of the key and an ArrayList of the values associated with it.
Insert ( object key, object val ) : void	Inserts a value into a bucket that is specified by the key.
Map ( ) : System	Default constructor.
