beforeProcess

public void beforeProcess(String rootNamespace,
                          Feed feed,
                          XMLStreamReader reader)

Description copied from interface: NamespaceCallbackHandler

Receives a callback before Namespace.process(PodcastParserContext) is invoked.

Note that any implementation must not move the reader. Doing so will cause an IllegalStateException to be thrown.

Specified by:

beforeProcess in interface NamespaceCallbackHandler

Parameters:

rootNamespace - String name of the root namespace (RSS|Atom)

feed - Feed instance in the process of being built

reader - XMLStreamReader instance, having just processed a XMLStreamConstants.START_ELEMENT event with this namespace.

beforeProcess

public void beforeProcess(String rootNamespace,
                          Item item,
                          XMLStreamReader reader)

Description copied from interface: NamespaceCallbackHandler

Receives a callback before Namespace.process(PodcastParserContext, Item) is invoked.

Note that any implementation must not move the reader. Doing so will cause an IllegalStateException to be thrown.

Specified by:

beforeProcess in interface NamespaceCallbackHandler

Parameters:

rootNamespace - String name of the root namespace (RSS|Atom)

item - Item instance in the process of being built

reader - XMLStreamReader instance, having just processed a XMLStreamConstants.START_ELEMENT event with this namespace.

registerUnknownNamespace

public void registerUnknownNamespace(String rootNamespace,
                                     XMLStreamReader reader,
                                     ParseLevel level)

Description copied from interface: NamespaceCallbackHandler

Receives a callback when an element is encountered for which no handling has been defined in this library.

Note that any implementation must not move the reader. Doing so will cause an IllegalStateException to be thrown.

Specified by:

registerUnknownNamespace in interface NamespaceCallbackHandler

Parameters:

rootNamespace - String name of the root namespace (RSS|Atom)

reader - XMLStreamReader instance, having just processed a XMLStreamConstants.START_ELEMENT event with the given namespace.

level - ParseLevel level at which the element is encountered

getCounter

public ElementCounter getCounter()

toString

public String toString()
