Class InjectionCycleOrError

java.lang.Object

org.ek9lang.compiler.phase5.InjectionCycleOrError

All Implemented Interfaces:

Consumer<org.antlr.v4.runtime.tree.ParseTree>

final class InjectionCycleOrError
extends Object
implements Consumer<org.antlr.v4.runtime.tree.ParseTree>

Detects circular dependencies in component injection chains per application (E08190).

The graph: each registered component type, with an edge to the component registered as the type of each of its injection fields. Its cycles are THE shared StronglyConnectedComponents (a self-injection is a cycle too), so each tangle of components is reported ONCE, at its member registered first, with one cycle through it as the path. The members are recorded on the application (InjectionCycles) so the ordering checks that follow do not report E08200 for them: in a cycle no registration order works (Steve, 2026-10-11).
