Public Member Functions | |
StandardFilter (const TokenStreamPtr &input) | |
Construct filtering input. | |
virtual | ~StandardFilter () |
virtual String | getClassName () |
boost::shared_ptr< StandardFilter > | shared_from_this () |
virtual bool | incrementToken () |
Returns the next token in the stream, or null at EOS. | |
![]() | |
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. | |
![]() | |
virtual | ~TokenStream () |
boost::shared_ptr< TokenStream > | shared_from_this () |
![]() | |
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. | |

TokenStream () | |
A TokenStream using the default attribute factory. | |

A TokenStream that uses the same attributes as the supplied one. | |
TokenStream (const AttributeFactoryPtr &factory) | |
A TokenStream using the supplied AttributeFactory for creating new Attribute instances. | |
