DefaultExtensibleInjectionEnvironment

abstract class DefaultExtensibleInjectionEnvironment(context: ExtensibleEnvironmentContext, metaContextKind: InjectionEnvironmentKind<*>) : ExtensibleInjectionEnvironment

Default implementation for ExtensibleInjectionEnvironment.

Constructors

fun DefaultExtensibleInjectionEnvironment(context: ExtensibleEnvironmentContext, metaContextKind: InjectionEnvironmentKind<*>)

Functions

createInjector

abstract fun <T : Any> createInjector(identifier: Identifier<T>, onInjection: (T) -> Unit = {}): Injector<T>

Creates an Injector that can be used as a property delegator, bound against the given identifier.

get

open fun <T : Any> get(identifier: Identifier<T>): T

Gets the component identified by the given identifier. No guarantees are given on this function - it may not be idempotent, depending on the actual implementation.

getAllIdentifiers

abstract fun getAllIdentifiers(): Sequence<Identifier<*>>

Returns a sequence of all the known identifiers present in this environment.

getOrNull

abstract fun <T : Any> getOrNull(identifier: Identifier<T>): T?

Gets the component identified by the given identifier, or null if no such component exists. No guarantees are given on this function - it may not be idempotent, depending on the actual implementation.

getResolverOrNull

abstract fun <T : Any> getResolverOrNull(identifier: Identifier<T>): IdentifierResolver<T>?

Returns the resolver associated with the given identifier.

Properties

metaEnvironment

open override val metaEnvironment: InjectionEnvironment

The meta environment for this environment.

Extensions

createMetaEnvironment

fun <T : InjectionEnvironment> ExtensibleInjectionEnvironment.createMetaEnvironment(context: ExtensibleEnvironmentContext, metaContextKind: InjectionEnvironmentKind<T>): T

Performs the internal logic required for setting up a meta-environment. When creating extensible environments, you should either call this function to create your meta environment, or subclass DefaultExtensibleInjectionEnvironment which will do it for you.

get

inline fun <T : Any> InjectionEnvironment.get(qualifier: Qualifier = EmptyQualifier): T

Gets the component identified by the given type turned into an Identifier with an optional qualifier. Throws an exception if no component with this identifier exists.

getOrNull

inline fun <T : Any> InjectionEnvironment.getOrNull(qualifier: Qualifier = EmptyQualifier): T?

Gets the component identified by the given type turned into an Identifier with an optional qualifier. Returns null if no component with this identifier exists.
