Base class for all ECS objects.

Provides a per-type auto-incrementing id and a default name derived from it and an optional parent reference for tree traversal.

callback(void callback()) → void: inherited
getAncestors() → Iterable<ECSBase<T>>: Returns every ancestor of this component, from immediate parent up to the root.
getDepth() → int: Returns the depth/level in the hierarchy.
getParentAs<P extends ECSBase<T>>() → P?: Returns parent cast to P, or null if the cast would fail.
getPath() → List<ECSBase<T>>: Returns the path from the root down to this one, inclusive.
hasParentOf<P extends ECSBase<T>>() → bool: Whether parent is of type P.

inherited
run(Task<T> task) → void: inherited
task(Task<T> task) → void: inherited
toString() → String: A string representation of this object.
override
uniqKey(String key) → String: Returns a key namespaced to this object's namedId.
