Collection

Implements an hash table whose keys are string and values are Variant.

NULL is used when nothing is associated with a given key. Consequently, associating NULL with a key is the same thing as removing it from the collection.

The size of the internal hash table grows dynamically as data is inserted.

This class is creatable.

DIM hCollection AS Collection

hCollection = NEW Collection ( [ Mode AS Integer ] )

Creates a new collection.

Mode is the method used for comparing keys:

This class acts like an array.

DIM hCollection AS Collection
DIM aVariant AS Variant

aVariant = hCollection [ Key AS String ]

Returns the value associated with Key.

If nothing is associated, then NULL is returned.

DIM hCollection AS Collection
DIM aVariant AS Variant

hCollection [ Key AS String ] = aVariant

Associates Value with _Key.

If Value is NULL , then the current value associated with Key is removed from the collection if it exists.

This class is enumerable with the FOR EACH keyword.

DIM hCollection AS Collection
DIM aVariant AS Variant

FOR EACH aVariant IN hCollection
  ...
NEXT

Enumerates each value stored in the collection.

Note that elements are enumerated in the order they were inserted. But if you replace the value of an already inserted key, then the order is kept.
