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

Fields in org.apache.lucene.util.fst declared as FST.Arc
`FST.Arc<T>` Util.FSTPath.`arc` Holds the last arc appended to this path

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
`FST.Arc<T>` FST.`readArcByDirectAddressing(FST.Arc<T> arc, FST.BytesReader in, int rangeIndex)` Reads a present direct addressing node arc, with the provided index in the label range.
`FST.Arc<T>` FST.`readArcByIndex(FST.Arc<T> arc, FST.BytesReader in, int idx)`
`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`.
`FST.Arc<T>` FST.`readFirstRealTargetArc(long nodeAddress, 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.`readLastArcByDirectAddressing(FST.Arc<T> arc, FST.BytesReader in)` Reads the last arc of a direct addressing node.
`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
