Examples with ResourceProvider com.vaadin.flow.di.ResourceProvider used on opensource projects

Example 26 with ResourceProvider

use of com.vaadin.flow.di.ResourceProvider in project flow by vaadin.

the class DefaultApplicationConfigurationFactory method getTokenFileFromClassloader.

/**
 * Gets token file from the classpath using the provided {@code context}.
 * <p>
 * The {@code contextClass} may be a class which is defined in the Web
 * Application module/bundle and in this case it may be used to get Web
 * Application resources. Also a {@link VaadinContext} {@code context}
 * instance may be used to get a context of the Web Application (since the
 * {@code contextClass} may be a class not from Web Application module). In
 * WAR case it doesn't matter which class is used to get the resources (Web
 * Application classes or e.g. "flow-server" classes) since they are loaded
 * by the same {@link ClassLoader}. But in OSGi "flow-server" module classes
 * can't be used to get Web Application resources since they are in
 * different bundles.
 *
 * @param context
 *            a VaadinContext which may provide information how to get token
 *            file for the web application
 * @return the token file content
 * @throws IOException
 *             if I/O fails during access to the token file
