| StopFilter (bool enablePositionIncrements, const TokenStreamPtr &input, HashSet< String > stopWords, bool ignoreCase=false) |
| Construct a token stream filtering the given input. If stopWords is an instance of CharArraySet (true if makeStopSet() was used to construct the set) it will be directly used and ignoreCase will be ignored since CharArraySet directly controls case sensitivity.

boost::shared_ptr< StopFilter > | shared_from_this () |
|
virtual bool | incrementToken () |
| Returns the next input Token whose term() is not a stop word.
|
|
bool | getEnablePositionIncrements () |
|
void | setEnablePositionIncrements (bool enable) |
| If true, this StopFilter will preserve positions of the incoming tokens (ie, accumulate and set position increments of the removed stop tokens). Generally, true is best as it does not lose information (positions of the original tokens) during indexing.
|
|
virtual | ~TokenFilter () |
|
boost::shared_ptr< TokenFilter > | shared_from_this () |
|
virtual void | end () |
| Performs end-of-stream operations, if any, and calls then end() on the input TokenStream. NOTE: Be sure to call TokenFilter::end() first when overriding this method.
|
|
virtual void | close () |
| Close the input TokenStream.
|
|
virtual void | reset () |
| Reset the filter as well as the input TokenStream.

|
| AttributeSource () |
| An AttributeSource using the default attribute factory DefaultAttributeFactory .
|
|
| AttributeSource (const AttributeSourcePtr &input) |
| An AttributeSource that uses the same attributes as the supplied one.
|
|
| AttributeSource (const AttributeFactoryPtr &factory) |
| An AttributeSource using the supplied AttributeFactory for creating new Attribute instances.
|
|
virtual | ~AttributeSource () |
|
boost::shared_ptr< AttributeSource > | shared_from_this () |
|
AttributeFactoryPtr | getAttributeFactory () |
| returns the used AttributeFactory.
|
|
template<class ATTR > |
boost::shared_ptr< ATTR > | addAttribute () |
| This method first checks if an instance of that class is already in this AttributeSource and returns it. Otherwise a new instance is created, added to this AttributeSource and returned.
|
|
void | addAttribute (const String &className, const AttributePtr &attrImpl) |
| Adds a custom Attribute instance.
|
|
bool | hasAttributes () |
| Returns true if this AttributeSource has any attributes.
|
|
template<class ATTR > |
bool | hasAttribute () |
| Returns true, if this AttributeSource contains the passed-in Attribute.
|
|
template<class ATTR > |
boost::shared_ptr< ATTR > | getAttribute () |
| Returns the instance of the passed in Attribute contained in this AttributeSource.
|
|
void | clearAttributes () |
| Resets all Attributes in this AttributeSource by calling AttributeImpl#clear() on each Attribute implementation.
|
|
AttributeSourceStatePtr | captureState () |
| Captures the state of all Attributes. The return value can be passed to restoreState to restore the state of this or another AttributeSource.
|
|
void | restoreState (const AttributeSourceStatePtr &state) |
| Restores this state by copying the values of all attribute implementations that this state contains into the attributes implementations of the targetStream. The targetStream must contain a corresponding instance for each argument contained in this state (eg. it is not possible to restore the state of an AttributeSource containing a TermAttribute into a AttributeSource using a Token instance as implementation).
|
|
virtual int32_t | hashCode () |
| Return hash code for this object.
|
|
virtual bool | equals (const LuceneObjectPtr &other) |
| Return whether two objects are equal.
|
|
virtual String | toString () |
| Returns a string representation of the object.
|
|
AttributeSourcePtr | cloneAttributes () |
| Performs a clone of all AttributeImpl instances returned in a new AttributeSource instance. This method can be used to eg. create another TokenStream with exactly the same attributes (using AttributeSource(AttributeSource) )
|
|
Collection< AttributePtr > | getAttributes () |
| Return a vector of attributes based on currentState.
|
|
virtual | ~LuceneObject () |
|
virtual void | initialize () |
| Called directly after instantiation to create objects that depend on this object being fully constructed.
|
|
virtual LuceneObjectPtr | clone (const LuceneObjectPtr &other=LuceneObjectPtr()) |
| Return clone of this object.
|
|
virtual int32_t | compareTo (const LuceneObjectPtr &other) |
| Compare two objects.
|
|
virtual | ~LuceneSync () |
|
virtual SynchronizePtr | getSync () |
| Return this object synchronize lock.
|
|
virtual LuceneSignalPtr | getSignal () |
| Return this object signal.
|
|
virtual void | lock (int32_t timeout=0) |
| Lock this object using an optional timeout.
|
|
virtual void | unlock () |
| Unlock this object.
|
|
virtual bool | holdsLock () |
| Returns true if this object is currently locked by current thread.
|
|
virtual void | wait (int32_t timeout=0) |
| Wait for signal using an optional timeout.
|
|
virtual void | notifyAll () |
| Notify all threads waiting for signal.
|
|
Removes stop words from a token stream.
void Lucene::StopFilter::setEnablePositionIncrements |
( |
bool |
enable | ) |
|
If true, this StopFilter will preserve positions of the incoming tokens (ie, accumulate and set position increments of the removed stop tokens). Generally, true is best as it does not lose information (positions of the original tokens) during indexing.
When set, when a token is stopped (omitted), the position increment of the following token is incremented.
NOTE: be sure to also set QueryParser#setEnablePositionIncrements
if you use QueryParser to create queries.
