Method Detail

getSyntax

public Syntax getSyntax()

Description copied from interface: FunDef

Returns the syntactic type of the function.

Specified by:

getSyntax in interface FunDef

getName

public String getName()

Description copied from interface: FunDef

Returns the name of this function.

Specified by:

getName in interface FunDef

getDescription

public String getDescription()

Description copied from interface: FunDef

Returns the description of this function.

Specified by:

getDescription in interface FunDef

getReturnCategory

public int getReturnCategory()

Description copied from interface: FunDef

Returns the Category code of the value returned by this function.

Specified by:

getReturnCategory in interface FunDef

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 by Exp.getCategory(). The 0^th 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 interface FunDef

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

getSignature

public String getSignature()

Description copied from interface: FunDef

Returns an English description of the signature of the function, for example "<Numeric Expression> / <Numeric Expression>".

Specified by:

getSignature in interface FunDef

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 interface FunDef

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
