                                         File file)

displayHTMLInBrowser

public static <I,D> void displayHTMLInBrowser(ObservationTable<I,D> table,
                                              Function<? super Word<? extends I>,? extends String> wordToString,

                                              UnsupportedOperationException

Displays the observation table as a HTML document in the default browser.

This method internally relies on Desktop.browse(java.net.URI), hence it will not work if Desktop is not supported, or if the application is running in headless mode.

IMPORTANT NOTE: Calling this method may delay the termination of the JVM by up to 5 seconds. This is due to the fact that the temporary file created in this method is marked for deletion upon JVM termination. If the JVM terminates too early, it might be deleted before it was loaded by the browser.

Parameters:

table - the observation table to display

wordToString - the transformation from words to strings. This transformation is not required nor expected to escape HTML entities

outputToString - the transformation from outputs to strings. This transformation is not required nor expected to escape HTML entities

Throws:

IOException - if creating or writing to the temporary file fails

HeadlessException - if the JVM is running in headless mode

UnsupportedOperationException - if Desktop.getDesktop() is not supported by the system

                                              UnsupportedOperationException
