Method Detail

getReusableComponents

public abstract Analyzer.TokenStreamComponents getReusableComponents(Analyzer analyzer,
                                                                     String fieldName)

Gets the reusable TokenStreamComponents for the field with the given name.

Parameters:

analyzer - Analyzer from which to get the reused components. Use getStoredValue(Analyzer) and setStoredValue(Analyzer, Object) to access the data on the Analyzer.

fieldName - Name of the field whose reusable TokenStreamComponents are to be retrieved

Returns:

Reusable TokenStreamComponents for the field, or null if there was no previous components for the field

setReusableComponents

public abstract void setReusableComponents(Analyzer analyzer,
                                           String fieldName,
                                           Analyzer.TokenStreamComponents components)

Stores the given TokenStreamComponents as the reusable components for the field with the give name.

Parameters:

fieldName - Name of the field whose TokenStreamComponents are being set

components - TokenStreamComponents which are to be reused for the field
