Uses of FST in org.apache.lucene.util.fst

Methods in org.apache.lucene.util.fst that return FST

Modifier and Type	Method and Description
FST<T>	Builder.finish() Returns final FST.
static <T> FST<T>	FST.read(Path path, Outputs<T> outputs) Reads an automaton from a file.

Methods in org.apache.lucene.util.fst with parameters of type FST

Modifier and Type	Method and Description
static <T> T	Util.get(FST<T> fst, BytesRef input) Looks up the output for this input, or null if the input is not accepted
static <T> T	Util.get(FST<T> fst, IntsRef input) Looks up the output for this input, or null if the input is not accepted.
static IntsRef	Util.getByOutput(FST<Long> fst, long targetOutput) Deprecated.
static IntsRef	Util.getByOutput(FST<Long> fst, long targetOutput, FST.BytesReader in, FST.Arc<Long> arc, FST.Arc<Long> scratchArc, IntsRefBuilder result) Deprecated.
static <T> FST.Arc<T>	Util.readCeilArc(int label, FST<T> fst, FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in) Reads the first arc greater or equal than the given label into the provided arc in place and returns it iff found, otherwise return null.
static <T> Util.TopResults<T>	Util.shortestPaths(FST<T> fst, FST.Arc<T> fromNode, T startOutput, Comparator<T> comparator, int topN, boolean allowEmptyString) Starting from node, find the top N min cost completions to a final node.
static <T> void	Util.toDot(FST<T> fst, Writer out, boolean sameRank, boolean labelStates) Dumps an FST to a GraphViz's dot language description for visualization.

Constructors in org.apache.lucene.util.fst with parameters of type FST

Constructor and Description
BytesRefFSTEnum(FST<T> fst) doFloor controls the behavior of advance: if it's true doFloor is true, advance positions to the biggest term before target.
IntsRefFSTEnum(FST<T> fst) doFloor controls the behavior of advance: if it's true doFloor is true, advance positions to the biggest term before target.
TopNSearcher(FST<T> fst, int topN, int maxQueueDepth, Comparator<T> comparator) Creates an unbounded TopNSearcher
TopNSearcher(FST<T> fst, int topN, int maxQueueDepth, Comparator<T> comparator, Comparator<Util.FSTPath<T>> pathComparator)
