Spec<T> constructor

A Jetleaf definition describing how a pod should be instantiated, configured, and managed inside the container.

A Spec acts as a fluent builder for pod registration. It allows chaining configuration methods for scope, lifecycle, dependencies, naming, and autowiring.

When to use

Use a Spec whenever you register a pod inside a Registry. It provides a structured, declarative way to define pod behaviors and their container interactions.

Example

registry.registerPod(MyService.classType, customizer: (spec) {
  spec
    .namedAs('myService')
    .withScope(ScopeType.singleton)
    .describedAs('Provides business logic services')
    .suppliedBy((ctx) => MyService(ctx.get(Dependency.classType)));
});

Fluent Chaining

All methods return the same Spec<T> instance, allowing chained invocations.
