Inherits Lucene.Net.Analysis.TokenFilter.

Public Member Functions
	LengthFilter (TokenStream in_Renamed, int min, int max)
	Build a filter that removes words that are too long or too short from the text.
override bool	IncrementToken ()
	Returns the next input Token whose term() is the right len
Public Member Functions inherited from Lucene.Net.Analysis.TokenFilter
override void	End ()
	Performs end-of-stream operations, if any, and calls then end() on the input TokenStream.NOTE: Be sure to call super.end() first when overriding this method.
override void	Reset ()
	Reset the filter as well as the input TokenStream.
Public Member Functions inherited from Lucene.Net.Analysis.TokenStream
void	Close ()
	Releases resources associated with this stream.
void	Dispose ()
Public Member Functions inherited from Lucene.Net.Util.AttributeSource
	AttributeSource ()
	An AttributeSource using the default attribute factory AttributeSource.AttributeFactory.DEFAULT_ATTRIBUTE_FACTORY.
	AttributeSource (AttributeSource input)
	An AttributeSource that uses the same attributes as the supplied one.
	AttributeSource (AttributeFactory factory)
	An AttributeSource using the supplied AttributeFactory for creating new IAttribute instances.
virtual IEnumerable< Type >	GetAttributeTypesIterator ()
	Returns a new iterator that iterates the attribute classes in the same order they were added in. Signature for Java 1.5: public Iterator<Class<? extends Attribute>> getAttributeClassesIterator()
virtual IEnumerable< Attribute >	GetAttributeImplsIterator ()
	Returns a new iterator that iterates all unique Attribute implementations. This iterator may contain less entries that GetAttributeTypesIterator, if one instance implements more than one Attribute interface. Signature for Java 1.5: public Iterator<AttributeImpl> getAttributeImplsIterator()
virtual void	AddAttributeImpl (Attribute att)
	Expert: Adds a custom AttributeImpl instance with one or more Attribute interfaces.
virtual T	AddAttribute< T > ()
	The caller must pass in a Class<? extends Attribute> value. 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.
virtual bool	HasAttribute< T > ()
	The caller must pass in a Class<? extends Attribute> value. Returns true, iff this AttributeSource contains the passed-in Attribute.
virtual T	GetAttribute< T > ()
	The caller must pass in a Class<? extends Attribute> value. Returns the instance of the passed in Attribute contained in this AttributeSource
virtual void	ClearAttributes ()
	Resets all Attributes in this AttributeSource by calling Attribute.Clear() on each Attribute implementation.
virtual State	CaptureState ()
	Captures the state of all Attributes. The return value can be passed to RestoreState to restore the state of this or another AttributeSource.
virtual void	RestoreState (State 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 (e.g. it is not possible to restore the state of an AttributeSource containing a TermAttribute into a AttributeSource using a Token instance as implementation).
override int	GetHashCode ()
override bool	Equals (System.Object obj)
override System.String	ToString ()
virtual AttributeSource	CloneAttributes ()
	Performs a clone of all Attribute instances returned in a new AttributeSource instance. This method can be used to e.g. create another TokenStream with exactly the same attributes (using AttributeSource(AttributeSource))

	Returns true, iff this AttributeSource has any attributes
