Classes in org.apache.lucene.util.fst used by org.apache.lucene.util.fst

Builder
Builds a minimal FST (maps an IntsRef term to an arbitrary output) from pre-sorted terms with outputs.

Builder.Arc
Expert: holds a pending (seen but not yet serialized) arc.

Builder.FreezeTail
Expert: this is invoked by Builder whenever a suffix is serialized.

Builder.UnCompiledNode
Expert: holds a pending (seen but not yet serialized) Node.

ByteSequenceOutputs
An FST Outputs implementation where each output is a sequence of bytes.

BytesRefFSTEnum.InputOutput
Holds a single input (BytesRef) + output pair.

CharSequenceOutputs
An FST Outputs implementation where each output is a sequence of characters.

FST
Represents an finite state machine (FST), using a compact byte[] format.

FST.Arc
Represents a single arc.

FST.BytesReader
Reads the bytes from this FST.

FST.INPUT_TYPE
Specifies allowed range of each int input label for this FST.

IntSequenceOutputs
An FST Outputs implementation where each output is a sequence of ints.

IntsRefFSTEnum.InputOutput
Holds a single input (IntsRef) + output pair.

NoOutputs
A null FST Outputs implementation; use this if you just want to build an FSA.

Outputs
Represents the outputs for an FST, providing the basic algebra required for building and traversing the FST.

PairOutputs.Pair
Holds a single pair of two outputs.

PositiveIntOutputs
An FST Outputs implementation where each output is a non-negative long value.

UpToTwoPositiveIntOutputs
An FST Outputs implementation where each output is one or two non-negative long values.

UpToTwoPositiveIntOutputs.TwoLongs
Holds two long outputs.

Util.MinResult
Holds a single input (IntsRef) + output, returned by shortestPaths().
