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)
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( ... );
