Syntax

PHP
class LJCCollectionBase

Represents a Collection of objects.

Remarks

The LJCCollectionBase class provides the code that can be inherited to create a strongly typed Collection.

It accomplishes this by implementing IteratorAggregate which provides "foreach" functionality and Countable which provides "count" functionality.

A strongly typed collection class would extend (inherit) from this base class and include an AddObject() method that would require the strongly typed object collection item. This is what makes the collection strongly typed.

The strongly typed collection class would also provide a Retrieve() method that could retrieve the internal array element by key.

For an example of how this works, see class: LJCDBAccessLib-LJCDbColumns. Use this code to include the Collection lib classes.
