final
class
switch
extends
StaticAnnotation
An annotation to be applied to a match expression. If present,
the compiler will verify that the match has been compiled to a
tableswitch
or
lookupswitch
, and issue an error if it
instead compiles into a series of conditional expressions.
Example:
def fetchToken() { (ch: @switch) match { case ' ' | '\t' | CR | LF | FF => nextChar() fetchToken() case 'A' /*..'Z'*/ | '$' | '_' | 'a' /*..'z'*/ => putChar(ch) nextChar() getIdentRest() case ',' => nextChar(); token = COMMA // more cases } }
