Singleton

class Singleton<C : Any, T : Any>(val scope: Scope<C>, val contextType: TypeToken<in C>, explicitContext: Boolean, val createdType: TypeToken<out T>, refMaker: RefMaker? = null, val sync: Boolean = true, val creator: NoArgBindingDI<C>.() -> T) : NoArgDIBinding<C, T>

Singleton Binding: will create an instance on first request and will subsequently always return the same instance.

constructor(scope: Scope<C>, contextType: TypeToken<in C>, explicitContext: Boolean, createdType: TypeToken<out T>, refMaker: RefMaker? = null, sync: Boolean = true, creator: NoArgBindingDI<C>.() -> T)

Properties

argType

open override val argType: TypeToken<Unit>
