SimpleServiceProvider

class SimpleServiceProvider : ServiceProvider

Simple implementation of ServiceProvider using thread-safe ConcurrentHashMap for storage. Provides basic service registration and retrieval functionality with support for both type-based and name-based lookups. Supports subtype matching for type-based lookups.

This implementation is suitable for most use cases requiring a lightweight, thread-safe service provider.

Constructors

constructor()

Properties

serviceNames

open override val serviceNames: Set<String>

Set of all registered service names. Returns a view of the keys in the namedServices map.

Functions

copy

open override fun copy(): SimpleServiceProvider

Creates a shallow copy of this service provider. The copy contains references to the same service instances but in separate maps.

copyTo

open override fun copyTo(target: ServiceProvider)

Copies all registered services from this provider to the target provider. Iterates through all named services and registers them with the target provider.

getService

open override fun <S : Any> getService(serviceName: String): S?

Retrieves a service by its registered name. Performs a direct lookup in the named services map.

open override fun <S : Any> getService(serviceType: KType): S?

Retrieves a service by its Kotlin type. First tries exact type match, then falls back to subtype matching if no exact match is found.

open override fun register(service: Any, serviceName: String = service.javaClass.toName(), serviceType: KType = service.javaClass.kotlin.defaultType)

Registers a service with the provider. Stores the service in both typed and named service maps for efficient lookup.
