6.4 Method Language
You have the choice of implementation language when creating a method within Caché.
Currently, there are three options: “Cache” (Caché ObjectScript), “Basic” , and “Java” .
By default, a method uses the language specified by its class' Language keyword. You can
override this on a method-by-method basis using the method's Language keyword:
Class MyApp.Test {
/// A Basic method
Method TestB() As %Integer [ Language = basic]
{
'This is Basic
Print "This is a test"
Return 1
}
/// A Cache ObjectScript method
Method TestC() As %Integer [ Language = cache]
{
// This is Cache ObjectScript
Write "This is a test"
Quit 1
}
}
Within a class, it is possible to have methods implemented in different languages. All methods
interoperate regardless of implementation language.
Caché ObjectScript and Basic methods are compiled into executable Caché code; Java
methods are treated differently. When you create a Java representation of a class (using the
Caché Java Binding), all of its Java methods are generated directly within the Java source.
This means that all Java methods run within a native JVM and have access to the complete
Java environment.
6.5 Method Keywords
You can modify a method definition through the use of one or more method keywords. Each
keyword is optional and has a default value if not explicitly specified.
The major method keywords are:
