## Detailed Description

Defines an abstract class that allows us to invoke commands without knowing anything about the implementation.

This class declares an interface to execute a command independent of the effect of the command, or the objects used to implement it.

## Constructor & Destructor Documentation

ACE_INLINE ACE_Command_Base::ACE_Command_Base ( | void )

| Default constructor.

ACE_INLINE ACE_Command_Base::~ACE_Command_Base ( | void )`[virtual]`

| Virtaul destructor.

## Member Function Documentation

int ACE_Command_Base::execute ( | void * arg = 0 )`[pure virtual]`

| Invokes the method encapsulated by the command, passing along the passed argument (if any). Users of classes derived from this class must ensure that the resulting invocation can tolerate a null void pointer being passed, or otherwise ensure that this will never occur. Reimplemented in ACE_Command_Callback.
