NAME
Genezzo::Havok::UserExtend - load the UserExtend table
SYNOPSIS
# don't say "use Genezzo::Havok::UserExtend". Update the
# dictionary havok table:insert into havok values (1, "Genezzo::Havok::UserExtend", "SYSTEM", "2004-09-21T12:12", 0);
DESCRIPTION
NOTE: this module is now deprecated and will be replaced by Genezzo::Havok::UserFunctions.
Basic Havok module - load the UserExtend table
create table user_extend ( xid number, xtype char, xname char, args char, owner char, creationdate char, version char );
- xid - a unique id number
- xtype - the string "require" or "function"
- xname - if xtype = "require", then xname is a package name, like "Text::Soundex". if xtype = "function", xname is a function name. A function name may be qualified with a package.
- args - if xtype = "require", an (optional) blank-separated list of functions to import to the default Genezzo namespace. if xtype = "function", supply an actual function body in curly braces.
- owner - owner of the package or function
- creationdate - date row was created
Example:
insert into user_extend values (1, 'require', 'Genezzo::Havok::Examples', 'isRedGreen', 'SYSTEM', '2004-09-21T12:12');
The row causes UserExtend to "require Genezzo::Havok::Examples", and it imports "isRedGreen" into the default Genezzo namespace* (actually, it creates a stub function that calls Genezzo::Havok::Examples::isRedGreen").
ARGUMENTS
FUNCTIONS
- isRedGreen
EXPORT
LIMITATIONS
TODO
- Need to fix "import" mechanism so can load specific functions into Genezzo::GenDBI namespace, versus creating stub functions. Use "import" and "export_to_level".
- Could just load Acme::Everything and we'd be done...
- Need function "type" information so can validate argument lists, determine return type of function
