6 ExtUtils::XSpp::Node::Function - Node representing a function
7
9 An ExtUtils::XSpp::Node subclass representing a single function
10 declaration such as
11
12 int foo();
13
14 More importantly, ExtUtils::XSpp::Node::Method inherits from this
15 class, so all in here equally applies to method nodes.
16
18 new
19 Creates a new "ExtUtils::XSpp::Node::Function".
20
21 Named parameters: "cpp_name" indicating the C++ name of the function,
22 "perl_name" indicating the Perl name of the function (defaults to the
23 same as "cpp_name"), "arguments" can be a reference to an array of
24 "ExtUtils::XSpp::Node::Argument" objects and finally "ret_type"
25 indicates the (C++) return type of the function.
26
27 Additionally, there are several optional decorators for a function
28 declaration (see ExtUtils::XSpp for a list). These can be passed to the
29 constructor as "code", "cleanup", "postcall", and "catch". "catch" is
30 special in that it must be a reference to an array of class names.
31
32 resolve_typemaps
33 Fetches the ExtUtils::XSpp::Typemap object for the return type and the
34 arguments from the typemap registry and stores a reference to those
35 objects.
36
37 resolve_exceptions
38 Fetches the ExtUtils::XSpp::Exception object for the %catch directives
39 associated with this function.
40
41 add_exception_handlers
42 Adds a list of exception names to the list of exception handlers. This
43 is mainly called by a class' "add_methods" method. If the function is
44 hard-wired to have no exception handlers, any extra handlers from the
45 class are ignored.
46
47 print_declaration
48 Returns a string with a C++ method declaration for the node.
49
50 perl_function_name
51 Returns the name of the Perl function to generate.
52
53 is_method
54 Returns whether the object at hand is a method. Hard-wired to be false
55 for "ExtUtils::XSpp::Node::Function" object, but overridden in the
56 ExtUtils::XSpp::Node::Method sub-class.
57
58 has_argument_with_length
59 Returns true if the function has any argument that uses the XS length
60 feature.
61
63 cpp_name
64 Returns the C++ name of the function.
65
66 perl_name
67 Returns the Perl name of the function (defaults to same as C++).
68
69 set_perl_name
70 Sets the Perl name of the function.
71
72 arguments
73 Returns the internal array reference of ExtUtils::XSpp::Node::Argument
74 objects that represent the function arguments.
75
76 ret_type
77 Returns the C++ return type.
78
79 code
80 Returns the %code decorator if any.
81
82 set_code
83 Sets the implementation for the method call (equivalent to using
84 %code); takes the code as an array reference containing the lines.
85
86 cleanup
87 Returns the %cleanup decorator if any.
88
89 postcall
90 Returns the %postcall decorator if any.
91
92 catch
93 Returns the set of exception types that were associated with the
94 function via %catch. (array reference)
95
96 aliases
97 Returns a hashref of "name => position" function name aliases (see
98 %alias and perlxs ALIAS keyword). Does not include the main function
99 name.
100
101 set_static
102 Sets the "static"-ness attribute of the function. Can be either undef
103 (i.e. not static), "package_static", or "class_static".
104
105 package_static
106 Returns whether the function is package static. A package static
107 function can be invoked as:
108
109 My::Package::Function( ... );
110
111 class_static
112 Returns whether the function is class static. A class static function
113 can be invoked as:
114
115 My::Package->Function( ... );
116
117 ret_typemap
118 Returns the typemap for the return value of the function.
119
120 set_ret_typemap( typemap )
121 Sets the typemap for the return value of the function.
122
123 arg_typemap( index )
124 Returns the typemap for one function arguments.
125
126 set_arg_typemap( index, typemap )
127 Sets the typemap for one function argument.
