using ComponentCreator = std::function<void(EntityComponentManager &, Entity, QStandardItem *)>

ComponentCreator is a function definition that a component can use to create the appropriate UI elements for an Entity based on a ComponentTypeId.

See also: void ComponentInspectorEditor::RegisterComponentCreator( UpdateCallback _cb)

◆ ComponentTypeId

using ComponentTypeId = uint64_t

A unique identifier for a component type. A component type must be derived from components::BaseComponent and can contain plain data or something more complex like gz::math::Pose3d.

◆ Entity

using Entity = uint64_t

An Entity identifies a single object in simulation such as a model, link, or light. At its core, an Entity is just an identifier.

An Entity usually has one or more associated Components. Components represent data, such as position information.

The set of Components assigned to an Entity also act as a key. Systems process Entities based on their key. For example, a physics system may process only entities that have pose and inertia components.

An Entity that needs to be identified and used by Systems should be created through the EntityComponentManager.

◆ EntityGraph

using EntityGraph = math::graph::DirectedGraph<Entity, bool>

Type alias for the graph that holds entities. Each vertex is an entity, and the direction points from the parent to its children. All edges are positive booleans.

◆ EntityQueryCallback

using EntityQueryCallback = std::function<void (const UpdateInfo, EntityComponentManager &)>

typedef for query callbacks

◆ SystemPluginPtr

using SystemPluginPtr = gz::plugin::SpecializedPluginPtr< System, ISystemConfigure, ISystemPreUpdate, ISystemUpdate, ISystemPostUpdate >

◆ UpdateCallback

using UpdateCallback = std::function<void(EntityComponentManager &)>

UpdateCallback is a function defition that is used by a component to manage ECM changes.

See also: void ComponentInspectorEditor::AddUpdateCallback(UpdateCallback _cb)
