- final case class TypedEntry[A](key: TypedKey[A], value: A) extends Product with Serializable
An entry that binds a typed key and a value.
An entry that binds a typed key and a value. These entries can be placed into a TypedMap or any other type of object with typed values.
- A
The type of the value.
- key
The key for this entry.
- value
The value for this entry.
- final class TypedKey[A] extends AnyRef
A TypedKey is a key that can be used to get and set values in a TypedMap or any object with typed keys.
A TypedKey is a key that can be used to get and set values in a TypedMap or any object with typed keys. This class uses reference equality for comparisons, so each new instance is different key.
- A
The type of values associated with this key.
- trait TypedMap extends AnyRef
A TypedMap is an immutable map containing typed values.
A TypedMap is an immutable map containing typed values. Each entry is associated with a TypedKey that can be used to look up the value. A
TypedKey
also defines the type of the value, e.g. aTypedKey[String]
would be associated with aString
value.Instances of this class are created with the
TypedMap.empty
method.The elements inside TypedMaps cannot be enumerated. This is a decision designed to enforce modularity. It's not possible to accidentally or intentionally access a value in a TypedMap without holding the corresponding TypedKey.
