Constructor Detail

Function

public Function(Declarator decl,
                Stmnt body)

Constructs a function.

Note: to parse a function declaration, the parser first tries to construct Declarator object but it discards that object and constructs Function object for substitution.

Parameters:

decl - the function name, the return type, and the argument list.

body - the function body.
