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

Methods in org.apache.lucene.util.fst that return FST
`FST<T>` `Builder.finish()` Returns final FST.
`FST<T>` `FST.pack(int minInCountDeref, int maxDerefNodes)` Expert: creates an FST by packing this one.

`static

`<T> FST<T>`

`

`FST.read(File file, Outputs<T> outputs)`
Reads an automaton from a file.

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

`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)` Reverse lookup (lookup by output instead of by input), in the special case when your FSTs outputs are strictly ascending.

`static

`<T> Util.MinResult<T>[]`

`

`Util.shortestPaths(FST<T> fst, FST.Arc<T> fromNode, Comparator<T> comparator, int topN)`
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
`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.
