Class: Singleton<V>
Class: Singleton<V>
Class representing a Singleton.
The Singleton class extends the ResolverBinding class, ensuring that the value is only resolved once. Subsequent calls to the resolve method will return the previously resolved value, making it behave as a singleton.

Properties
resolver
protected readonly resolver: Resolver<V>;
The resolver function used to provide the binding value.
This function will be called when the value is needed, allowing for lazy instantiation and dependency resolution. It should return an instance of type V.
Inherited from
value?
protected optional value: V;
The value held by the binding.
This value is resolved at runtime, either directly or through a resolver function.

Methods
isResolved()
protected isResolved(): boolean;
Check if the value has been resolved.
Returns
boolean
A boolean indicating whether the value has been resolved.
Inherited from

The container to resolve dependencies from.
Returns
undefined | V
The resolved value of the binding.
Throws
ContainerError if the value cannot be resolved.
