Classes

Array

Information

An array of Type.

The Array Element is the way maximum multiplicity greater than 1 is implemented for individual Type.

Property

Contained type

The type on the items contained by the Array.

Constructors

Array (Initial capacity: Natural* [0..1] = 64, Contained type: ISA\LL\Metamodel\AbstractDataType [0..1])

Build an array of a given capacity for a given type.

The array is initialized to point to the universal type instance ISA\LL\Model\Root.

Array (Initializer: String[0..∞])

Build an array from a given list items by inferring their Type and values.

Destructor

Delete()

Decrements references count on all the objects contained by the array, and then delete the array.

Array

Stream

Information

A Stream supports the flow of objects over the time. This abstract class is root of all streams.

This class and its children are for system purpose and should not be used directly. The user only uses the In stream or Out stream views provided by the Stream factory (System assembly).

There are 2 ways a Stream can by read:

By notification of a Consumer. Here the Stream drives the consumption.
By calling the Get queries. Here the Consumer drives the consumption.

Field

Consumer: Stream consumer<T> [0..1]

The consumer of the flow.

Property

Contained type : <T> 恒

The type on the elements flowing through the Stream.

Attribute

End : Boolean = False

The end of the stream reach.

Command

Add(Value : <T>)	Add a Value to the stream.
Get next() : <T>	Get a Value from the stream.
Subscribe(Consumer: Stream consumer<T>)	Subscribe to be notified when a new Value is available on the stream. Only one subscriber is allowed since a stream is dedicated to one consumer. The consumer destruction perform the unsubscription.
Unsubscribe()	Unsubscribe the current consumer.
