+Represents a collection of a set of key and value pairs. Each key in the HashMap +must be unique, the same key cannot exist twice. Access to items is provided via +the key only. Sample usage: +
var map = new Ext.util.HashMap();
+map.add('key1', 1);
+map.add('key2', 2);
+map.add('key3', 3);
+
+map.each(function(key, value, length){
+ console.log(key, value, length);
+});
+The HashMap is an unordered class, +there is no guarantee when iterating over the items that they will be in any particular +order. If this is required, then use a Ext.util.MixedCollection. +
+ +A function that is used to retrieve a default key for a passed object. +A default is provided that returns the id property on the object. This function is only used +if the add method is called with a single argument.
+Adds an item to the collection. Fires the add event when complete.
+Adds an item to the collection. Fires the add event when complete.
+The key to associate with the item, or the new item.
+ + +If a getKey implementation was specified for this HashMap, +or if the key of the stored items is in a property called id, +the HashMap will be able to derive the key for the new item. +In this case just pass the new item in this parameter.
+ +The item to add.
+The item added.
+Removes all items from the hash.
+Removes all items from the hash.
+this
+Performs a shallow copy on this hash.

+The new hash object.
+Checks whether a value exists in the hash.
+Checks whether a value exists in the hash.
+The value to check for.
+True if the value exists in the dictionary.
+Checks whether a key exists in the hash.
+Checks whether a key exists in the hash.
+The key to check for.
+True if they key exists in the hash.
+Executes the specified function once for each item in the hash. +Returning false from the function will cease iteration.
+ +The paramaters passed to the function are:
+ +The key of the item
The value of the item
The total number of items in the hash
The function to execute.
+The scope to execute in. Defaults to this.
+this
