Method Summary

Calc	compileCall(ResolvedFunCall call, ExpCompiler compiler) Converts a call to this function into executable objects.
Exp	createCall(Validator validator, Exp[] args) Creates an expression which represents a call to this function with a given set of arguments.
Type	getResultType(Validator validator, Exp[] args) 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.

Method Detail

compileCall

public Calc compileCall(ResolvedFunCall call,
                        ExpCompiler compiler)

Description copied from interface: FunDef

Converts a call to this function into executable objects.

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.

Specified by:

compileCall in interface FunDef

Overrides:

compileCall in class FunDefBase

createCall

public Exp createCall(Validator validator,
                      Exp[] args)

Description copied from interface: FunDef

Creates an expression which represents a call to this function with a given set of arguments. The result is usually a ResolvedFunCall but not always.

Specified by:

createCall in interface FunDef

Overrides:

createCall in class FunDefBase

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 class FunDefBase

Parameters:

validator - Validator

args - Arguments to the call to this operator

Returns:

result type of a call this function
