# Mutable preferences objects
|
|
|
|
## Context and Problem Statement
|
|
|
|
To create an immutable preferences object every time seems to be a waste of time and computer memory.
|
|
|
|
## Considered Options
|
|
|
|
* Alter the existing object and return it (by a `with*` -method, similar to a builder, but changing the object at hand).
|
|
* Create a new object every time a preferences object should be altered.
|
|
|
|
## Decision Outcome
|
|
|
|
Chosen option: "Alter the exiting object", because the preferences objects are just wrappers around the basic preferences framework of JDK. They
|
|
should be mutable on-the-fly similar to objects with a Builder inside and to be stored immediately again in the
|
|
preferences.
