FacadeTaskHelper

• java.lang.Object

Fields Summary
private Vector	args Command line arguments.
private String	userChoice The explicitly chosen implementation.
private String	magicValue The magic property to consult.
private String	defaultValue The default value.

Constructors Summary
public FacadeTaskHelper(String defaultValue) param defaultValue The default value for the implementation. Must not be null. this(defaultValue, null);
public FacadeTaskHelper(String defaultValue, String magicValue) param defaultValue The default value for the implementation. Must not be null. param magicValue the value of a magic property that may hold a user. choice. May be null. this.defaultValue = defaultValue; this.magicValue = magicValue;

Methods Summary
public void	addImplementationArgument(ImplementationSpecificArgument arg) Command line argument. param arg an argument to add. args.addElement(arg);
public java.lang.String[]	getArgs() Retrieves the command line arguments enabled for the current facade implementation. return an array of command line arguements. Vector tmp = new Vector(args.size()); for (Enumeration e = args.elements(); e.hasMoreElements();) { ImplementationSpecificArgument arg = ((ImplementationSpecificArgument) e.nextElement()); String[] curr = arg.getParts(getImplementation()); for (int i = 0; i < curr.length; i++) { tmp.addElement(curr[i]); } } String[] res = new String[tmp.size()]; tmp.copyInto(res); return res;
public java.lang.String	getExplicitChoice() Retrieves the explicit user choice. return the explicit user choice. return userChoice;
public java.lang.String	getImplementation() Retrieves the implementation. return the implementation. return userChoice != null ? userChoice : (magicValue != null ? magicValue : defaultValue);
public boolean	hasBeenSet() Tests whether the implementation has been chosen by the user (either via a magic property or explicitly. return true if magic or user choice has be set. since Ant 1.5.2 return userChoice != null || magicValue != null;
public void	setImplementation(java.lang.String userChoice) Used for explicit user choices. param userChoice the explicitly chosen implementation. this.userChoice = userChoice;
public void	setMagicValue(java.lang.String magicValue) Used to set the value of the magic property. param magicValue the value of a magic property that may hold a user. this.magicValue = magicValue;
