function literals造句

• D also supports function literals, that allow a lambda-style definition:
• Then the'map'method of arrays is used on'a', and it takes a function literal which returns the square of its parameter.
• Notice a function literal can be defined either with an identifier ( " twice " ) or anonymously ( assigned to variable " f " ).
• The Java syntax has been gradually extended in the course of the eight major JDK releases support capabilities such as generic programming and function literals ( called lambda expressions in Java ).
• Anonymous functions ( function literals ) are defined using lambda expressions, e . g . ( lambda ( x ) ( * x x ) ) for a function that squares its argument.
• There are two built-in types for function literals, function, which is simply a pointer to a stack-allocated function, and delegate, which also includes a pointer to the surrounding environment.
