Method Detail

setAnalyzer

CompassAnalyzerHelper setAnalyzer(String analyzerName)
                                  throws CompassException

Sets the analyzer that will be used for the analysis of the text.

Parameters:

analyzerName - The analyzer name that will be used.

Returns:

the analyzer helper

Throws:

CompassException

setAnalyzer

CompassAnalyzerHelper setAnalyzer(Resource resource)
                                  throws CompassException

Sets the analyzer that will be used for the analysis of the text. Uses the resource to derive the analyzer that will be used (works also with per resource property analyzer).

Parameters:

resource - The resource to derive the analyzer from

Returns:

the analyzer helper

Throws:

CompassException

setAnalyzerByAlias

CompassAnalyzerHelper setAnalyzerByAlias(String alias)
                                         throws CompassException

Sets the analyzer that will be used for the analysis of the text. Uses the alias to get the mapping deinfitions and build a specific analyzer if there is a certain property that is associated with a specific analyzer (builds a per resource property analyzer).

Parameters:

alias - The alias to derive the analyzer from

Returns:

the analyzer helper

Throws:

CompassException - If the analyzer if not found

analyzeSingle

CompassToken analyzeSingle(String text)
                           throws CompassException

Analyzes the given text, returning the first token.

Parameters:

text - The text to analyze

Returns:

The first token.

Throws:

CompassException

analyze

CompassToken[] analyze(String text)
                       throws CompassException

Analyzes the given text, returning a set of tokens.

Parameters:

text - The text to analyze

Returns:

A set of tokens resulting from the analysis process.

Throws:

CompassException

analyze

CompassToken[] analyze(String propertyName,
                       String text)
                       throws CompassException

Analyzes the given text, using (if needed) the anlayzer that is bound to the supplied property. Should be used with setAnalyzer(Resource) so the analyzer can be dynamically detected from the resource.

Parameters:

propertyName - The property name for analyze bound properties

text - The text to analyze

Returns:

A set of tokens resulting from the analysis process.

Throws:

CompassException

analyze

CompassToken[] analyze(Reader textReader)
                       throws CompassException

Analyzes the given text, returning a set of tokens.

Parameters:

textReader - The text to analyze

Returns:

A set of tokens resulting from the analysis process.

Throws:

CompassException

analyze

CompassToken[] analyze(String propertyName,
                       Reader textReader)
                       throws CompassException

Analyzes the given text, using (if needed) the anlayzer that is bound to the supplied property. Should be used with setAnalyzer(Resource) so the analyzer can be dynamically detected from the resource.

Parameters:

propertyName - The property name for analyze bound properties

textReader - The text to analyze

Returns:

A set of tokens resulting from the analysis process.

Throws:

CompassException
