Method Detail

createPublishPermission

public static Object createPublishPermission(String topic)

Creates a TopicPermission for the given topic and the type PUBLISH Note that a java.lang.Object is returned in case creating a new TopicPermission fails. This assumes that Bundle.hasPermission is used in order to evaluate the created Permission which in turn will return true if security is not supported by the framework. Otherwise, it will return false due to receiving something that is not a subclass of java.lang.SecurityPermission hence, this combination ensures that access is granted in case a topic permission could not be created due to missing security support by the framework.

Parameters:

topic - The target topic

Returns:

The created permission or a java.lang.Object in case the permission could not be created.
