// A {@code Collector} is specified by four functions that work together to // accumulate entries into a mutable result container, and optionally perform // a final transform on the result. They are: // creation of a new result container ({@link #supplier()}) // incorporating a new d...
ref=appYou can see here that the same string defined in any point of the app has the same memory position. With this you don't waste memory declaring the same object multiple times. Because of a string is defined in many places if there was mutable a change to one will...

For example, StringBuilder is a mutable reference type in the .NET framework library, through which the string value of an instance created out of this type can be modified by appending, removing, replacing or inserting characters. A mutable type should not be derived from an immutable type bec...
How can the key path type be inferred? The answer to this is easy. It infers from the properties/subscripts and a root type.If properties or subscripts are read-only (such as let or subscript with only get), KeyPath is inferred. If it is mutable (such as var or subscript with get/...
