Examples with Attributes java.util.jar.Attributes used on opensource projects

Example 66 with Attributes

use of java.util.jar.Attributes in project bnd by bndtools.

the class AnnotationHeadersTest method testMultipleManifestHeaders.

/**
	 * Say I want to define a capability namespace for web applications, e.g.
	 * Provide-Capability: webapp; webapp=Petstore. Web application components
	 * necessarily require an HTTP implementation so they should
	 * Require-Capability: osgi.implementation;
	 * filter:="(osgi.implementation=osgi.http)". I want to define an annotation
	 * that I can put onto a component that implies both the above provide and
	 * require. I tried the following:
	 * 
	 * <pre>
	 * &#64;ProvideCapability(ns = "webapp")
	 * &#64;RequireCapability(ns = "osgi.implementation", filter = "(osgi.implementation=osgi.http)")
	 * &#64;interface WebApplication {
	 * 	String name();
	 * }
	 * 
	 * &#64;WebApplication(name = "Petstore")
	 * &#64;Component
	 * public class PetstoreAppComponent {
	 * 	// ..
	 * }
	 * </pre>
	 * 
	 * However this only generated the Provide, it did not generate the Require.
	 * If I switch the order of annotations so that @RequireCapability is first,
	 * then it only generates the Require.
