## fr.gouv.culture.sdx.search.lucene.analysis
Class AnalyzerManager

    java.lang.Object
      fr.gouv.culture.sdx.utils.AbstractSdxObject
          fr.gouv.culture.sdx.search.lucene.analysis.AnalyzerManager

All Implemented Interfaces:
  org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.context.Contextualizable, Describable, Encodable, Identifiable, Localizable, org.apache.avalon.framework.logger.LogEnabled, SdxObject, org.apache.avalon.framework.service.Serviceable, org.apache.excalibur.xml.sax.XMLizable

public class AnalyzerManager
extends AbstractSdxObject

Utility class for managing Lucene analyzers in a multilingual context.

Lucene analyzers are used for indexing and querying a Lucene index. An analyzer is specific to a language, so in a multilingual context we need a way to manage analyzers.

Most SDX applications will share the same analyzers for popular languages and contexts. In order to reuse resources, we will create only one AnalyzerManager and attach it to the framework.

Analyzers used within this manager will each have a unique key. This key will be a combination of the locale and the configuration file used.

Constructor Detail

### AnalyzerManager

    public AnalyzerManager()

  Builds a manager.

  Only one manager is needed for a running SDX installation. It is created and managed by the SDX framework.

Method Detail

### configure

    public void configure(org.apache.avalon.framework.configuration.Configuration configuration)
                   throws org.apache.avalon.framework.configuration.ConfigurationException

  Configures the manager.

  For now, no specific configuration is needed.

  Specified by:
    `configure` in interface `org.apache.avalon.framework.configuration.Configurable`
  Overrides:
    `configure` in class `AbstractSdxObject`
  Throws:
    `org.apache.avalon.framework.configuration.ConfigurationException`

### getAnalyzer

    public Analyzer getAnalyzer(java.util.Locale locale,
                                java.io.File configurationFile)
                         throws SDXException

  Adds an analyzer given a locale and a configuration file.

  Parameters:
    `locale` - The givene locale, cannot be null
    `configurationFile` - An XML file for configuring the analyzer (may be null)
  Throws:
    `SDXException`

### getAnalyzer

    public Analyzer getAnalyzer(java.lang.String className,
                                java.io.File configurationFile)
                         throws SDXException

  Adds an analyzer using a specific class name and a configuration file.

  Parameters:
    `className` - The name of the class to use.
    `configurationFile` - The configuration file for the analyzer (may be null)
  Throws:
    `SDXException`

### getClassNameSuffix

    protected java.lang.String getClassNameSuffix()

  Description copied from class: `AbstractSdxObject`
  Sub classes should element this method to return their class name suffix for SAX output

  Specified by:
    `getClassNameSuffix` in class `AbstractSdxObject`

### initToSax

    protected boolean initToSax()

  Description copied from class: `AbstractSdxObject`
  Init the LinkedHashMap _xmlizable_objects with the objects in order to describ them in XML

  Specified by:
    `initToSax` in class `AbstractSdxObject`

### initVolatileObjectsToSax

    protected void initVolatileObjectsToSax()

  Init the LinkedHashMap _xmlizable_volatile_objects with the objects in order to describ them in XML Some objects need to be refresh each time a toSAX is called

  Specified by:
    `initVolatileObjectsToSax` in class `AbstractSdxObject`
