public int getReturnCategory()
FunDef
Category
code of the value returned by this
function.
getReturnCategory
in interface FunDef
getReturnCategory
in class FunDefBase
public int[] getParameterCategories()
FunDef
Exp.getCategory()
. The 0th
argument of methods and properties are the object they are applied
to. Infix operators have two arguments, and prefix operators have one
argument.

public Calc compileCall(ResolvedFunCall call, ExpCompiler compiler)
FunDef
The result must implement the appropriate interface for the result
type. For example, a function which returns an integer must return
an object which implements IntegerCalc
.
