Class CompiledAutomaton
Immutable class holding compiled details for a given
Automaton. The Automaton is deterministic, must not have
dead states but is not necessarily minimal.
Note
This API is experimental and might change in incompatible ways in the next release.

Floor(BytesRef, BytesRef)
Finds largest term accepted by this Automaton, that's
<= the provided input term. The result is placed in
output; it's fine for output and input to point to
the same BytesRef. The returned result is either the
provided output, or null
if there is no floor term
(ie, the provided input term is before the first term
accepted by this Automaton).
Declaration
public virtual BytesRef Floor(BytesRef input, BytesRef output)
