SystemManager

class SystemManager

Manages the lifecycle and execution of systems within the Spatial SDK.

SystemManager is responsible for organizing, prioritizing, and executing systems in a deterministic order based on their dependencies. It maintains a directed acyclic graph (DAG) of systems to ensure proper execution order and handles system registration, discovery, and lifecycle management.

Systems can be registered with different priority groups (EARLY, NORMAL, LATE) to control their relative execution order. The manager ensures systems are executed in topologically sorted order based on their dependencies and priority groups.

Example usage:

// Register a system
systemManager.registerSystem(MyCustomSystem())

// Find a system by class
val avatarSystem = systemManager.findSystem<AvatarSystem>()

The SystemManager is created and managed by AppSystemActivity or other activity classes that extend from VrActivity.
