Method Detail

getReturnCategory
public int getReturnCategory()
Description copied from interface:FunDef
Returns theCategory
code of the value returned by this function.- Specified by:
getReturnCategory
in interfaceFunDef
- Overrides:
getReturnCategory
in classFunDefBase
-
getParameterCategories
public int[] getParameterCategories()
Description copied from interface:FunDef
Returns the types of the arguments of this function. Values are the same as those returned byExp.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.- Specified by:
getParameterCategories
in interfaceFunDef
- Overrides:
getParameterCategories
in classFunDefBase
-
unparse
public void unparse(Exp[] args, PrintWriter pw)
Description copied from interface:FunDef
Converts a function call into MDX source code.- Specified by:
unparse
in interfaceFunDef
- Overrides:
unparse
in classFunDefBase
-
getResultType
public Type getResultType(Validator validator, Exp[] args)
Description copied from class:FunDefBase
Returns the type of a call to this function with a given set of arguments. The default implementation makes the coarse assumption that the return type is in some way related to the type of the first argument. Operators whose arguments don't follow the requirements of this implementation should override this method. If the function definition says it returns a literal type (numeric, string, symbol) then it's a fair guess that the function call returns the same kind of value. If the function definition says it returns an object type (cube, dimension, hierarchy, level, member) then we check the first argument of the function. Suppose that the function definition says that it returns a hierarchy, and the first argument of the function happens to be a member. Then it's reasonable to assume that this function returns a member.- Overrides:
getResultType
in classFunDefBase
- Parameters:
validator
- Validatorargs
- Arguments to the call to this operator- Returns:
- result type of a call this function
