Language (Method Keyword)
Usage
To specify the language used to implement the method, use the following syntax:
Method name(formal_spec) As returnclass [ Language = language ]
{ //implementation }
Where language is one of the following:
-
objectscript (the default) — ObjectScript
-
python — Embedded Python
-
tsql — Transact-SQL
-
ispl — Informix Stored Procedure Language
Details
This keyword specifies the language used to implement this method.
The values ispl and tsql are only supported for class methods.
If you specify a value of ispl, the body of the method is limited to a single CREATE PROCEDURE statement.
Default
If you omit this keyword, the language specified by the class-level Language keyword is used.
You cannot specify Language = ispl or Language = python at the class level; you can only use these values for methods.
Methods for sharded classes cannot be implemented using any language other than ObjectScript.
Examples
Class User.Person Extends %Persistent
{
Property Name As %String;
Property Gender As %String;
/// An ObjectScript instance method that writes the name and gender of a person
Method Write() [ Language = objectscript ]
{
write !, ..Name, " is a ", ..Gender, !
}
/// An Embedded Python instance method that prints the name and gender of a person
Method Print() [ Language = python ]
{
print('\n' + self.Name + ' is a ' + self.Gender)
}
/// A TSQL class method that inserts a row into the Person table
ClassMethod TSQLTest() [ Language = tsql ]
{
INSERT INTO Person (Name, Gender) VALUES ('Manon', 'Female')
}
/// An ISPL class method that creates a stored procedure named IsplSp
ClassMethod ISPLTest() [ Language = ispl ]
{
CREATE PROCEDURE IsplSp()
INSERT INTO Person (Name, Gender) VALUES ('Nikolai', 'Male')
END PROCEDURE
}
}
