Constructor Detail

CmdInterpreter

public CmdInterpreter(JPiv jpiv,
                      java.lang.String handleName)

Creates a new instance of a java2.CmdInterpreter. The java2.CmdInterpreter starts applications, executes native console commands and interpretes java code. For interpreting java code the bsh.eval(String str) method of the bsh package (BeanShell) is used. Methods of an already constructed instance of a jpiv2.JPiv class can be referred to in a script or command via the automatically generated handle with the name handleName. Use the get... methods of the jpiv2.JPiv object to get handles to other objects. e.g. myHandle = handleName.getSettingsFrame();

Parameters:

jpiv - The jpiv2.JPiv object which methods you would like to use.

handleName - The name via that you would like to refere to the jpiv2.JPiv object.

Method Detail

execute

public void execute(java.lang.String[] command,
                    int type)

Executes a command. The command and its parameters (or the filename containing a bsh-script) are given as elements of an array. If javacode is or a bsh-script file given, only the first array element (index 0) is taken.

Parameters:

command - An array containing a command string and parameters or the name of a bsh-script file.

type - A constant. The constant specifies wether the command is executed directly, within an operating-system-specific shell or by the BeanShell java interpreter.
