org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/CompilerConfigurationBlock.java
for (int i= 0; i < allKeys.length; i++) {
				if (settings.get(allKeys[i]) != null) {
					return true;
				}
			}
		}
		return false;
	}	
		
	private void setOptions(Map map) {
		if (fProject != null) {
			fProject.setOptions(map);
		} else {
			JavaCore.setOptions((Hashtable) map);
		}	
	} 
	
	/**
	 * Returns the shell.
	 * @return Shell
	 */
	public Shell getShell() {
		return fShell;
	}	
	
	/**
