IContext interface models a simple hash map that allows tiles to store attibutes
in name-value pairs. The name-value pairs are uniquely identified by their names, and any tile can
reference a name-value pair using the unique identifier.
The context is specific to its accessor. For example, the mosaicApp.context is shared for the application, whereas the IView.context is shared for only the specific view.

public function addAttributesWatcher(name:Array, listener:Object, tile:com.adobe.mosaic.om.interfaces:ITile):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 9.5 |
| Versioni runtime: | AIR 2.6, Flash Player 10.2 |
Adds a watcher to a specific set of context attributes.
The watcher only triggers when all the attributes are set by a call to setAttributes that
matches the list of watched attributes.
Parametri
name:Array — The name of the context object to watch.
| |
listener:Object — A function that takes in one parameter of type PropertyChangeEvent that will be
called any time a set is called with this name.
| |
tile:com.adobe.mosaic.om.interfaces:ITile — The tile that added the watcher. The tile must be specified in order for the tile
to observe its contextWatcherPolicy

| Versioni runtime: | AIR 2.6, Flash Player 10.2 |
Adds a watcher to the context.
The context watchers behave similar to watchers in Flex, with the exception that the context attributes do not need to be set in advance of creating the watcher. This way a tile can watch for an attribute that has not previously been set.
Parametri
name:String — The name of the context object to watch.

listener:Object — A function that takes in one parameter of type PropertyChangeEvent that will be called any time a set is called with this name.
| |
tile:com.adobe.mosaic.om.interfaces:ITile — The ITile with the reference to the attribute being watched

Sets a single attribute in the context to a value. Attribute names must follow the variable naming conventions in ActionScript (must start with a letter, etc).
Parametri
name:String — The name of the attribute to set.

setAttributes | () | metodo |
public function setAttributes(names:Array, values:Array):void| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Adobe Digital Enterprise Platform Experience Services - Composite Application Framework 9.5 |
| Versioni runtime: | AIR 2.6, Flash Player 10.2 |
Sets an array of context attributes.
This method differs from setAttribute() in that it sets the values of many attributes at once. If a watcher for this set of attributes was previously added with addAttributesWatcher(), then this method will trigger a PropertyChangeEvent.
Example:
context.addAttributesWatcher(arrayAttributeNames, handleContextAttributesChanged, m_tileThis);
context.setAttributes(arrayAttributeNames, arrayAttributeValues);
// Handler for the multiple-attributes-changed event caused by IContext.setAttributes()
private function handleContextAttributesChanged(event:PropertyChangeEvent):void {
var nNumAttributesNames:int = event.property.length;
var strNewAttributeValuesInfo:String = "";
for (var nAttributeCounter:int = 0; nAttributeCounter < nNumAttributesNames; nAttributeCounter++) {
var strAttributeName:String = event.property[nAttributeCounter].toString();
var strOldAttributeValue:String = event.oldValue[nAttributeCounter].toString();
var strNewAttributeValue:String = event.newValue[nAttributeCounter].toString();
strNewAttributeValuesInfo += 'Attribute "' + strAttributeName + '" value changed from "' + strOldAttributeValue + '" to "' + strNewAttributeValue + '"';
}
Alert.show(strNewAttributeValuesInfo);
}
Parametri
names:Array — An array of the names of attributes to set in the context.
| |
values:Array — An array of the values to set for the attributes.
