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

    java.lang.Object
      org.apache.lucene.analysis.Analyzer
          fr.gouv.culture.sdx.search.lucene.analysis.AbstractAnalyzer
              fr.gouv.culture.sdx.search.lucene.analysis.MetaAnalyzer

All Implemented Interfaces:
  Analyzer, org.apache.avalon.framework.configuration.Configurable, org.apache.avalon.framework.logger.LogEnabled, java.io.Serializable, org.apache.excalibur.xml.sax.XMLizable

public class MetaAnalyzer
extends AbstractAnalyzer

A dispatcher for field specific analyzers.

This analyzer knows about specific analyzers for the fields of a document base. Hence, when its tokenStream(fieldName, reader) method is called, it attempts to dispatch the task to a specific analyzer for the given field name.

Field Detail

### ANALYZER_TYPE

    protected static final java.lang.String ANALYZER_TYPE

See Also:
  Constant Field Values

Constructor Detail

### MetaAnalyzer

    public MetaAnalyzer()

  Creates a MetaAnalyzer

  A super.getLog() must be set and then this MetaAnalyzer must be setUp.

See Also:
  `setUp(fr.gouv.culture.sdx.search.lucene.FieldList)`

Method Detail

### getAnalyzerType

    protected java.lang.String getAnalyzerType()

  Specified by:
    `getAnalyzerType` in class `AbstractAnalyzer`

### setUp

    public void setUp(FieldList fields)
               throws SDXException

  Builds an analyzer with definitions for fields.

  Parameters:
    `fields` - The fields and their definitions (cannot be null).
  Throws:
    `SDXException`

### tokenStream

    public org.apache.lucene.analysis.TokenStream tokenStream(java.lang.String fieldName,
                                                              java.io.Reader reader)

  Tokenizes contents.

  The tokenizing is never done by this object. Instead, using the provided field name, it will try to get a specific analyzer from the fields definition. If it can't find one, it will use the default analyzer.

  Parameters:
    `fieldName` - The field name for tokenization
    `reader` - The reader

### getFieldList

    public FieldList getFieldList()

  Returns a the FieldList for this MetaAnalyzer (basically a Hashtable of all the Fields)

  Returns:
    FieldList

### tokenStream

    public org.apache.lucene.analysis.TokenStream tokenStream(java.io.Reader reader)

  Deprecated. use tokenStream(String, Reader) instead.

  Creates a TokenStream which tokenizes all the text in the provided Reader. Provided for backward compatibility only.

  See Also:
    `Analyzer.tokenStream(java.io.Reader)`
