Package modelarium.attributes.builtins.events

package modelarium.attributes.builtins.events

Provides built-in Event implementations for common event-triggering patterns.

These event classes allow model behaviour to be expressed using reusable time-based and state-based triggers rather than requiring a custom event class for each case. Examples include triggering at fixed tick intervals or when a property value crosses a threshold.

Built-in events typically operate on properties belonging to an associated ModelElement and may execute one or more built-in or custom actions when triggered. Some event implementations maintain internal state in order to distinguish between a new trigger condition and one that is simply continuing to hold.

These events are intended to support common modelling scenarios while remaining composable with the rest of the Modelarium attribute system. Where more specific or domain-dependent behaviour is required, users may implement custom Event subclasses.
