ExtUtils::XSpp::Node::Function(3)

NAME
ExtUtils::XSpp::Node::Function - Node representing a function

DESCRIPTION
An ExtUtils::XSpp::Node subclass representing a single function declaration such as

  int foo();

More importantly, ExtUtils::XSpp::Node::Method inherits from this class, so all in here equally applies to method nodes.

METHODS

  new
Creates a new "ExtUtils::XSpp::Node::Function".

Named parameters: "cpp_name" indicating the C++ name of the function, "perl_name" indicating the Perl name of the function (defaults to the same as "cpp_name"), "arguments" can be a reference to an array of "ExtUtils::XSpp::Node::Argument" objects and finally "ret_type" indicates the (C++) return type of the function.

Additionally, there are several optional decorators for a function declaration (see ExtUtils::XSpp for a list). These can be passed to the constructor as "code", "cleanup", "postcall", and "catch". "catch" is special in that it must be a reference to an array of class names.

  resolve_typemaps
Fetches the ExtUtils::XSpp::Typemap object for the return type and the arguments from the typemap registry and stores a reference to those objects.

  resolve_exceptions
Fetches the ExtUtils::XSpp::Exception object for the %catch directives associated with this function.

  add_exception_handlers
Adds a list of exception names to the list of exception handlers. This is mainly called by a class' "add_methods" method. If the function is hard-wired to have no exception handlers, any extra handlers from the class are ignored.

  print_declaration
Returns a string with a C++ method declaration for the node.

  perl_function_name
Returns the name of the Perl function to generate.

  is_method
Returns whether the object at hand is a method. Hard-wired to be false for "ExtUtils::XSpp::Node::Function" object, but overridden in the ExtUtils::XSpp::Node::Method sub-class.

  has_argument_with_length
Returns true if the function has any argument that uses the XS length feature.

ACCESSORS

  cpp_name
Returns the C++ name of the function.

  perl_name
Returns the Perl name of the function (defaults to same as C++).

  set_perl_name
Sets the Perl name of the function.

  arguments
Returns the internal array reference of ExtUtils::XSpp::Node::Argument objects that represent the function arguments.

  ret_type
Returns the C++ return type.

  code
Returns the %code decorator if any.

  set_code
Sets the implementation for the method call (equivalent to using %code); takes the code as an array reference containing the lines.

  cleanup
Returns the %cleanup decorator if any.

  postcall
Returns the %postcall decorator if any.

  catch
Returns the set of exception types that were associated with the function via %catch. (array reference)

  aliases
Returns a hashref of "name => position" function name aliases (see %alias and perlxs ALIAS keyword). Does not include the main function name.

  set_static
Sets the "static"-ness attribute of the function. Can be either undef (i.e. not static), "package_static", or "class_static".

  package_static
Returns whether the function is package static. A package static function can be invoked as:

    My::Package::Function( ... );

  class_static
Returns whether the function is class static. A class static function can be invoked as:

    My::Package->Function( ... );

  ret_typemap
Returns the typemap for the return value of the function.

  set_ret_typemap( typemap )
Sets the typemap for the return value of the function.

  arg_typemap( index )
Returns the typemap for one function arguments.

  set_arg_typemap( index, typemap )
Sets the typemap for one function argument.
