Class CommandList

java.lang.Object
  com.ibm.as400.access.CommandList

All Implemented Interfaces:

Serializable

public class CommandList
extends Object
implements Serializable

The CommandList class represents a list of CL command (*CMD) objects on the system. This class allows the user to retrieve a list of Command objects which can then be used to retrieve information about each individual CL command in the list.

The following example demonstrates the use of CommandList:

    AS400 system = new AS400("mySystem");

    // Generate a list of commands that start with "CRT".
    CommandList list = new CommandList(system, "QSYS", "CRT*");
    try
    {
        Command[] cmdList = list.generateList();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

Constructor Detail

CommandList

public CommandList()

Constructs a CommandList object.

CommandList

public CommandList(AS400 system,
                   String library,
                   String command)

Constructs a CommandList object.

Parameters:

system - The system on which the commands resides.

library - The library in which the commands resides, e.g. "QSYS".

command - The name of a command or list of commands, e.g. "CRTUSRPRF" or "CRT*". Wildcards or the CommandList.ALL constant can be used.

Method Detail

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a PropertyChangeListener. The specified PropertyChangeListener's propertyChange method will be called each time the value of any bound property is changed. The PropertyChangeListener object is added to a list of PropertyChangeListeners managed by this CommandList. It can be removed with removePropertyChangeListener.

Parameters:

listener - The PropertyChangeListener.

getCommand

public String getCommand()

Returns the command name used to generate a list for.

Returns:

The command, or null if no command has been set.

See Also:

setCommand(java.lang.String)

getLibrary

public String getLibrary()

Returns the library where the command(s) reside.

Returns:

The library, or null if no library has been set.

See Also:

setLibrary(java.lang.String)

getSystem

public AS400 getSystem()

Returns the system from which to retrieve the command list.

Returns:

The system from which to retrieve the commands, or null if no system has been set.

generateList

public Command[] generateList()
                       throws AS400Exception,
                              AS400SecurityException,
