Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description

`void`	`clear()`	Clears the context.
`String[]`	`getContextFunctionNames()`	Returns context element accessor function names.

- Method Detail
  - getContextFunctionNames
```
String[] getContextFunctionNames()
```
    Returns context element accessor function names. Implementations override this method to add specific context elements accessors.
    
    Returns:
    
    the context element accessor function names
  - callback
```
Object callback(String method,
                Object arg)
```
    Implements CallbackIface. Implementations override this method to implement the specific context elements accessors returned by getContextFunctionNames().
    
    Specified by:
    
    callback in interface chemaxon.marvin.util.CallbackIface
    
    Parameters:
    
    method - is the accessor method name (returned by getContextFunctionNames())
    
    arg - is the accessor method argument (the JEP parameter stack as null, a single parameter object or a parameter object array depending on the number of parameters on the stack)
    
    Returns:
    
    the context element
  - clear
```
void clear()
```
    Clears the context.
