Classes in org.apache.lucene.util.fst used by org.apache.lucene.util.fst
Class and Description
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.
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 bytes stored in an FST.
FST.INPUT_TYPE Specifies allowed range of each int input label for this FST.
FSTStore Abstraction for reading/writing bytes necessary for 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.
Util.FSTPath Represents a path in TopNSearcher.
Util.Result Holds a single input (IntsRef) + output, returned by `shortestPaths()`.
Util.TopResults Holds the results for a top N search using `Util.TopNSearcher`
