java.lang.Object org.apache.wicket.markup.MarkupFactory
public class MarkupFactory
Factory to load markup either from from cache or from a resource. In case of markup inheritance, merging the markup is managed transparently.

Markup |
getMarkup(MarkupContainer container,
boolean enforceReload)
Get the markup associated with the container. |
Markup |
getMarkup(MarkupContainer container,
Class<?> clazz,
boolean enforceReload)
Get the markup associated with the container. |
IMarkupCache |
getMarkupCache()
Get the markup cache which is registered with the factory. |
IMarkupLoader |
getMarkupLoader()
MarkupLoaders are responsible to find and load the markup for a component. |
MarkupResourceStream |
getMarkupResourceStream(MarkupContainer container,
Class<?> clazz)
Create a new markup resource stream for the container. |
protected IMarkupResourceStreamProvider |
getMarkupResourceStreamProvider(MarkupContainer container)
Get the markup resource stream provider registered with the factory. |
boolean |
hasAssociatedMarkup(MarkupContainer container)
Check if container has associated markup |
boolean |
hasMarkupCache()
|
Markup |
loadMarkup(MarkupContainer container,
MarkupResourceStream markupResourceStream,
boolean enforceReload)
Loads markup from a resource stream. |
MarkupParser |
newMarkupParser(MarkupResourceStream resource)
Create a new markup parser. |
protected IXmlPullParser |
newXmlPullParser()
Subclasses can override this to use custom parsers. |
protected IMarkupFilter |
onAppendMarkupFilter(IMarkupFilter filter)
A callback method that is invoked prior to any IMarkupFilter being registered with
MarkupParser . |

public static final MarkupFactory get()

DefaultMarkupLoader
will be returned. Via
subclassing you may return your markup loader..public MarkupParser newMarkupParser(MarkupResourceStream resource)
MarkupElement
's (kind of Wicket's DOM).
MarkupParser's can be extended by means of IMarkupFilter
. You can add your own filter
as follows:
public MyMarkupFactory { ... public MarkupParser newMarkupParser(final MarkupResourceStream resource) { MarkupParser parser = super.newMarkupParser(resource); parser.add(new MyFilter()); return parser; } }
resource
- The resource containing the markup

onAppendMarkupFilter(IMarkupFilter)
protected IXmlPullParser newXmlPullParser()
MarkupParser
to parse markup.protected IMarkupFilter onAppendMarkupFilter(IMarkupFilter filter)
IMarkupFilter
being registered with
MarkupParser
. Hence it allows to:
MarkupParser
instance is created for each markup resources being
loaded.
filter
- The filter to be registered with the MarkupParser
public IMarkupCache getMarkupCache()
Please note that markup cache is a pull through cache. It'll invoke a factory method
getMarkupResourceStream(MarkupContainer, Class)
to load the markup if not yet
available in the cache.
public boolean hasMarkupCache()
true
if markup cache is available. Make sure you called
getMarkupCache()
at least once before to initialize the cache.public final Markup getMarkup(MarkupContainer container, boolean enforceReload)
container
- The container to find the markup forenforceReload
- If true, the cache will be ignored and all, including inherited markup files, will
be reloaded. Whatever is in the cache, it will be ignored
public final Markup getMarkup(MarkupContainer container, Class<?> clazz, boolean enforceReload)
container
- The container to find the markup forclazz
- Must be the container class or any of its super classes.enforceReload
- The cache will be ignored and all, including inherited markup files, will be
reloaded. Whatever is in the cache, it will be ignored
public final boolean hasAssociatedMarkup(MarkupContainer container)
container
- The container to find the markup for
protected final IMarkupResourceStreamProvider getMarkupResourceStreamProvider(MarkupContainer container)
If the 'container' implements IMarkupResourceStreamProvider
, the container itself
will be asked to provide the resource stream. Else Wicket's default implementation will be
used.
container
- The MarkupContainer requesting the markup resource stream
public final MarkupResourceStream getMarkupResourceStream(MarkupContainer container, Class<?> clazz)
container
- The MarkupContainer which requests to load the Markup resource streamclazz
- Either the container class or any super class
public final Markup loadMarkup(MarkupContainer container, MarkupResourceStream markupResourceStream, boolean enforceReload)
container
- The original requesting markup containermarkupResourceStream
- The markup resource stream to load. May be null.enforceReload
- The cache will be ignored and all, including inherited markup files, will be
reloaded. Whatever is in the cache, it will be ignored
