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

Methods in org.apache.lucene.util.fst that return FST.Arc
`FST.Arc<T>` `FST.Arc.copyFrom(FST.Arc<T> other)` Returns this
`FST.Arc<T>` `FST.findTargetArc(int labelToMatch, FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Finds an arc leaving the incoming arc, replacing the arc in place.
`FST.Arc<T>` `FST.getFirstArc(FST.Arc<T> arc)` Fills virtual 'start' arc, ie, an empty incoming arc to the FST's start node

`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 that the given label into the provided arc in place and returns it iff found, otherwise return `null`.

`FST.Arc<T>` `FST.readFirstRealTargetArc(long node, FST.Arc<T> arc, FST.BytesReader in)`
`FST.Arc<T>` `FST.readFirstTargetArc(FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Follow the `follow` arc and read the first arc of its target; this changes the provided `arc` (2nd arg) in-place and returns it.
`FST.Arc<T>` `FST.readLastTargetArc(FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Follows the `follow` arc and reads the last arc of its target; this changes the provided `arc` (2nd arg) in-place and returns it.
`FST.Arc<T>` `FST.readNextArc(FST.Arc<T> arc, FST.BytesReader in)` In-place read; returns the arc.
`FST.Arc<T>` `FST.readNextRealArc(FST.Arc<T> arc, FST.BytesReader in)` Never returns null, but you should never call this if arc.isLast() is true.

Methods in org.apache.lucene.util.fst with parameters of type FST.Arc
`void` `Util.TopNSearcher.addStartPaths(FST.Arc<T> node, T startOutput, boolean allowEmptyString, IntsRef input)` Adds all leaving arcs, including 'finished' arc, if the node is final, from this node into the queue.
`FST.Arc<T>` `FST.Arc.copyFrom(FST.Arc<T> other)` Returns this
`FST.Arc<T>` `FST.findTargetArc(int labelToMatch, FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Finds an arc leaving the incoming arc, replacing the arc in place.
`FST.Arc<T>` `FST.findTargetArc(int labelToMatch, FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Finds an arc leaving the incoming arc, replacing the arc in place.
`static IntsRef` `Util.getByOutput(FST<Long> fst, long targetOutput, FST.BytesReader in, FST.Arc<Long> arc, FST.Arc<Long> scratchArc, IntsRef result)` Expert: like `Util.getByOutput(FST, long)` except reusing BytesReader, initial and scratch Arc, and result.
`static IntsRef` `Util.getByOutput(FST<Long> fst, long targetOutput, FST.BytesReader in, FST.Arc<Long> arc, FST.Arc<Long> scratchArc, IntsRef result)` Expert: like `Util.getByOutput(FST, long)` except reusing BytesReader, initial and scratch Arc, and result.
`FST.Arc<T>` `FST.getFirstArc(FST.Arc<T> arc)` Fills virtual 'start' arc, ie, an empty incoming arc to the FST's start node

`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 that the given label into the provided arc in place and returns it iff found, otherwise return `null`.

`static

`<T> FST.Arc<T>`

`

`Util.readCeilArc(int label, FST<T> fst, FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)`

`FST.Arc<T>` `FST.readFirstRealTargetArc(long node, FST.Arc<T> arc, FST.BytesReader in)`
`FST.Arc<T>` `FST.readFirstTargetArc(FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Follow the `follow` arc and read the first arc of its target; this changes the provided `arc` (2nd arg) in-place and returns it.
`FST.Arc<T>` `FST.readFirstTargetArc(FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Follow the `follow` arc and read the first arc of its target; this changes the provided `arc` (2nd arg) in-place and returns it.
`FST.Arc<T>` `FST.readLastTargetArc(FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Follows the `follow` arc and reads the last arc of its target; this changes the provided `arc` (2nd arg) in-place and returns it.
`FST.Arc<T>` `FST.readLastTargetArc(FST.Arc<T> follow, FST.Arc<T> arc, FST.BytesReader in)` Follows the `follow` arc and reads the last arc of its target; this changes the provided `arc` (2nd arg) in-place and returns it.
