protected |
CharFilterFactory(Map<String,String> args)
Initialize this factory via a set of key-value pairs.
|
Modifier and Type | Method and Description |
---|---|
static Set<String> |
availableCharFilters()
returns a list of all available charfilter names
|
abstract Reader |
create(Reader input)
Wraps the given Reader with a CharFilter.
|
static String |
findSPIName(Class<? extends CharFilterFactory> serviceClass)
looks up a SPI name for the specified char filter factory
|
static CharFilterFactory |
forName(String name,
Map<String,String> args)
looks up a charfilter by name from context classpath
|
static Class<? extends CharFilterFactory> |
lookupClass(String name)
looks up a charfilter class by name from context classpath
|
Reader |
normalize(Reader input)
Normalize the specified input Reader
While the default implementation returns input unchanged,
char filters that should be applied at normalization time can delegate to
create method. |
static void |
reloadCharFilters(ClassLoader classloader)
Reloads the factory list from the given
ClassLoader . |

Changes to the factories are visible after the method ends, all
iterators (availableCharFilters()
,...) stay consistent.
NOTE: Only new factories are added, existing ones are never removed or replaced.
This method is expensive and should only be called for discovery of new factories on the given classpath/classloader!
