Context Management

Tile context acts like a cache, holding the content that is relevant for one or more tiles.

There are two types of contexts:

Local – the context that belongs to a specific tile, which is updated with binding data, or with data passed from or updated by other tiles.
Global – acts like a versatile, central in-memory cache, from which you can manage any custom objects that are identified by a unique ID.

Global Context Management
The global context is a central repository for custom key-value pairs that are available to both application development and configuration. You can place, retrieve, and delete global context values based on their unique keys.
Automatic and Explicit Context Updates
Supported context management methods include both automatic and explicit context updates.
Responses to Context Update Events
The target tile can use the {$_context.<value>} syntax to access passed values in its local context.
