how come an ImmutableMap has a non-final property? #1335

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
How come a supposedly immutable class ImmutableMap has a non-final property 
"entrySet"? I had an impression that immutable classes have only final 
properties.

See 
http://stackoverflow.com/questions/11282219/why-string-class-is-immutable-even-t
hough-it-has-a-non-final-field-called-hash .  The reasoning is the same: it's a 
fiels  computed on demand that causes no harm if it's never computed at all or 
even multiple times.
