Interface representing a monetary rounding. Rounding must not necessarily represent roundings in a pure arithmetical sense. Basically a rounding
can scale an amount arbitrarily.

Implementation specification

Implementations of this interface must be

    
    
  • final
    • 
    
  • immutable
    • 
    
  • thread-safe
    • 


Implementations of this interface should be

    
    
  • serializable
    •

Access the rounding's context, which gives more details of the rounding instances such as

    
    
  • The rounding's name (required)
    • 
    
  • Its provider (required)
    • 
    
  • Its base currency
    • 
    
  • its scale and rounding mode
    • 
    
  • any other attributes useful to describe the rounding
    • 



Returns:the rounding's context, never null.
