Method Detail

getBrowser

protected StandardUnixBrowser getBrowser(String key)

Provides access the browsers map for extending classes.

Parameters:

key - String

Returns:

StandardUnixBrowser

openUrlWithBrowser

protected boolean openUrlWithBrowser(UnixBrowser unixBrowser,
                                     String urlString)
                              throws BrowserLaunchingExecutionException

Attempts to open a url with the specified browser. This is a utility method called by the openUrl methods.

Parameters:

unixBrowser - UnixBrowser

urlString - String

Returns:

boolean

Throws:

BrowserLaunchingExecutionException

initialize

public void initialize()
                throws BrowserLaunchingInitializingException

Uses the which command to find out which browsers are available. The available browsers are put into the unixBrowsers map using displayName => StandardUnixBrowser mappings.

Specified by:

initialize in interface IBrowserLaunching

Throws:

BrowserLaunchingInitializingException

openUrl

public void openUrl(String urlString)
             throws UnsupportedOperatingSystemException,
                    BrowserLaunchingExecutionException,
                    BrowserLaunchingInitializingException

Opens a url in one of the available browsers.

Specified by:

openUrl in interface IBrowserLaunching

Parameters:

urlString - String

Throws:

BrowserLaunchingExecutionException

UnsupportedOperatingSystemException

BrowserLaunchingInitializingException

openUrl

public void openUrl(String browser,
                    String urlString)
             throws UnsupportedOperatingSystemException,
                    BrowserLaunchingExecutionException,
                    BrowserLaunchingInitializingException

Opens a url in the specified browser. If the call to the specified browser fails, the method falls through to the non-targetted version.

Specified by:

openUrl in interface IBrowserLaunching

Parameters:

browser - String

urlString - String

Throws:

UnsupportedOperatingSystemException

BrowserLaunchingExecutionException

BrowserLaunchingInitializingException

openUrl

public void openUrl(List browsers,
                    String urlString)
             throws UnsupportedOperatingSystemException,
                    BrowserLaunchingExecutionException,
                    BrowserLaunchingInitializingException

Allows user to target several browsers. The names of potential browsers can be accessed via the getBrowserList method.

The browsers from the list will be tried in order (first to last) until one of the calls succeeds. If all the calls to the requested browsers fail, the code will fail over to the default browser.

Specified by:

openUrl in interface IBrowserLaunching

Parameters:

browsers - List

urlString - String

Throws:

UnsupportedOperatingSystemException

BrowserLaunchingExecutionException

BrowserLaunchingInitializingException

getBrowserList

public List getBrowserList()

Returns a list of browsers to be used for browser targetting. This list will always contain at least one item--the BROWSER_DEFAULT.

Specified by:

getBrowserList in interface IBrowserLaunching

Returns:

List

getNewWindowPolicy

public boolean getNewWindowPolicy()

Returns the policy used for opening a url in a browser.

If the policy is true, an attempt will be made to force the url to be opened in a new instance (window) of the browser.

If the policy is false, the url may open in a new window or a new tab.

Most browsers on Unix/Linux systems have command line options to support this feature.

Specified by:

getNewWindowPolicy in interface IBrowserLaunching

Returns:

boolean

setNewWindowPolicy

public void setNewWindowPolicy(boolean forceNewWindow)

Sets the policy used for opening a url in a browser.

Specified by:

setNewWindowPolicy in interface IBrowserLaunching

Parameters:

forceNewWindow - boolean
