Constructor Detail

Analyzer.ReuseStrategy

public Analyzer.ReuseStrategy()

Sole constructor. (For invocation by subclass constructors, typically implicit.)

Method Detail

getReusableComponents

public abstract Analyzer.TokenStreamComponents getReusableComponents(String fieldName)

Gets the reusable TokenStreamComponents for the field with the given name

Parameters:

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(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

getStoredValue

protected final Object getStoredValue()

Returns the currently stored value

Returns:

Currently stored value or null if no value is stored

Throws:

AlreadyClosedException - if the ReuseStrategy is closed.

setStoredValue

protected final void setStoredValue(Object storedValue)

Sets the stored value

Parameters:

storedValue - Value to store

Throws:

AlreadyClosedException - if the ReuseStrategy is closed.

close

public void close()

Closes the ReuseStrategy, freeing any resources
