interface ConditionInterface

An interface for condition plugins.

Condition plugins are context-aware and configurable. They support the following keys in their plugin definitions:

• context: An array of context definitions, keyed by context name. Each context definition is a typed data definition describing the context. Check the typed data definition docs for details.
• configuration: An array of configuration option definitions, keyed by option name. Each option definition is a typed data definition describing the configuration option. Check the typed data definition docs for details.

@todo Replace the dependency on \Drupal\Core\Form\FormInterface with a new interface from https://www.drupal.org/node/2006248. @todo WARNING: The condition API is going to receive some additions before release. The following additions are likely to happen:

• The way configuration is handled and configuration forms are built is likely to change in order for the plugin to be of use for Rules.
• Conditions will receive a data processing API that allows for token replacements to happen outside of the plugin implementations, see https://www.drupal.org/node/2347023.
• Conditions will have to implement access control for checking who is allowed to configure or perform the action at https://www.drupal.org/node/2172017.
