Examples of IResourceStream

org.apache.wicket.util.resource.IResourceStream
Interface to a streamed resource. The resource stream can be retrieved by calling getInputStream(), but the resource should later be closed by calling close() on the IResourceStream (as opposed to calling close on the InputStream returned by getInputStream()).
Once a resource has been closed with a call to close(), it is normally possible to call getInputStream() again to retrieve a new input stream on the same resource.
Implementations of this interface are typically unsafe for use from multiple threads. @author Jonathan Locke
