In object-oriented (OO) and functional programming, an immutable object (unchangeable object) is an object whose state cannot be modified after it is...

A properly written constructor leaves the resulting object in a valid state. Immutable objects must be initialized in a constructor. Most languages allow...

early incarnations of object storage were used for archiving, as implementations were optimized for data services like immutability, not performance. EMC...
