All Implemented Interfaces:

Resolver

public class ReflectiveMultiResolver
extends MultiResolver

Resolver which uses reflection to instantiate a FunDef. This reduces the amount of anonymous classes.

Method Detail

createFunDef

protected FunDef createFunDef(Exp[] args,
                              FunDef dummyFunDef)

Specified by:

createFunDef in class MultiResolver

getReservedWords

public String[] getReservedWords()

Description copied from interface: Resolver

Returns an array of symbolic constants which can appear as arguments to this function.

For example, the DrilldownMember may take the symbol RECURSIVE as an argument. Most functions do not define any symbolic constants.

Specified by:

getReservedWords in interface Resolver

Overrides:

getReservedWords in class MultiResolver

Returns:

An array of the names of the symbolic constants
