Method Detail

initialize

void initialize()
                throws BrowserLaunchingInitializingException

Performs any initialization needed for the particular O/S.

Throws:

BrowserLaunchingInitializingException

openUrl

void openUrl(java.lang.String urlString)
             throws UnsupportedOperatingSystemException,
                    BrowserLaunchingExecutionException,
                    BrowserLaunchingInitializingException

Opens the passed url in the system's default browser.

Parameters:

urlString - String

Throws:

UnsupportedOperatingSystemException

BrowserLaunchingExecutionException

BrowserLaunchingInitializingException

openUrl

void openUrl(java.lang.String browser,
           java.lang.String urlString)
             throws UnsupportedOperatingSystemException,
                    BrowserLaunchingExecutionException,
                    BrowserLaunchingInitializingException

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

If the call to the requested browser fails, the code will fail over to the default browser.

Parameters:

browser - String

urlString - String

Throws:

UnsupportedOperatingSystemException

BrowserLaunchingExecutionException

BrowserLaunchingInitializingException

openUrl

void openUrl(java.util.List browsers,
           java.lang.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.

Parameters:

browsers - List

urlString - String

Throws:

UnsupportedOperatingSystemException

BrowserLaunchingExecutionException

BrowserLaunchingInitializingException

getBrowserList

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

Returns:

List

getNewWindowPolicy

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.

Results will vary based on the O/S and browser being targetted.

Returns:

boolean

setNewWindowPolicy

void setNewWindowPolicy(boolean forceNewWindow)

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

Parameters:
