Interface FunTable

All Known Implementing Classes:

BuiltinFunTable, CustomizedFunctionTable, FunTableImpl, GlobalFunTable, RolapSchema.RolapSchemaFunctionTable

public interface FunTable

List of all MDX functions. A function table can resolve a function call, using a particular Syntax and set of arguments, to a function definition (FunDef).

Method Summary

FunDef	getDef(Exp[] args, Validator validator, String funName, Syntax syntax) Resolves a function call to a particular function.
List<FunInfo>	getFunInfoList() Returns a list of FunInfo objects.
List<String>	getReservedWords() Returns a list of words (String) which may not be used as identifiers.
List<Resolver>	getResolvers() Returns a list of Resolver objects.
boolean	isProperty(String s) Returns whether a string is a property-style (postfix) operator.
boolean	isReserved(String s) Returns whether a string is a reserved word.
boolean	requiresExpression(UnresolvedFunCall funCall, int k, Validator validator) Returns whether the kth argument to a function call has to be an expression.

Method Detail

getDef

FunDef getDef(Exp[] args,
              Validator validator,
              String funName,
              Syntax syntax)

Resolves a function call to a particular function. If the function is overloaded, returns as precise a match to the argument types as possible.

isReserved

boolean isReserved(String s)

Returns whether a string is a reserved word.

isProperty

boolean isProperty(String s)

Returns whether a string is a property-style (postfix) operator. This is used during parsing to disambiguate functions from unquoted member names.

requiresExpression

boolean requiresExpression(UnresolvedFunCall funCall,
                           int k,
                           Validator validator)

Returns whether the kth argument to a function call has to be an expression.

getReservedWords

List<String> getReservedWords()

Returns a list of words (String) which may not be used as identifiers.

getResolvers

List<Resolver> getResolvers()

Returns a list of Resolver objects.

getFunInfoList

List<FunInfo> getFunInfoList()

Returns a list of FunInfo objects.
