void filterSymbols(List<ConstantDefinition> constants,
                   List<FunctionSymbol> functions)
```
    Filters the given constant and function symbols. The caller will query the SymbolFilter for its resulting constant and function symbol lists after this routine returns.
    
    Parameters:
    
    defines - a list of Define objects
    
    functions - a list of FunctionSymbol objects
  - getConstants
```
List<ConstantDefinition> getConstants()
```
    Returns the filtered list of constants. This method may return a new list, the original list, or null, in which case the original list will be used.
  - getFunctions
