Method Detail
-
forName
public static TokenizerFactory forName(String name, Map<String,String> args)
looks up a tokenizer by name from context classpath
-
lookupClass
public static Class<? extends TokenizerFactory> lookupClass(String name)
looks up a tokenizer class by name from context classpath
-
availableTokenizers
public static Set<String> availableTokenizers()
returns a list of all available tokenizer names from context classpath
-
findSPIName
public static String findSPIName(Class<? extends TokenizerFactory> serviceClass)
looks up a SPI name for the specified tokenizer factory
-
reloadTokenizers
public static void reloadTokenizers(ClassLoader classloader)
Reloads the factory list from the givenClassLoader. Changes to the factories are visible after the method ends, all iterators (availableTokenizers(),...) 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!
-
create
public final Tokenizer create()
Creates a TokenStream of the specified input using the default attribute factory.
-
create
public abstract Tokenizer create(AttributeFactory factory)
Creates a TokenStream of the specified input using the given AttributeFactory
