Example 17 with ComponentMetadata

use of org.apache.felix.scr.impl.metadata.ComponentMetadata in project felix by apache.

the class ComponentRegistry method checkComponentName.

// ---------- ComponentHolder registration by component name
/**
 * Checks whether the component name is "globally" unique or not. If it is
 * unique, it is reserved until the actual component is registered with
 * {@link #registerComponentHolder(String, ComponentHolder)} or until
 * it is unreserved by calling {@link #unregisterComponentHolder(String)}.
 * If a component with the same name has already been reserved or registered
 * a ComponentException is thrown with a descriptive message.
 *
 * @param bundle the bundle registering the component
 * @param name the component name to check and reserve
 * @throws ComponentException if the name is already in use by another
 *      component.
