## org.apache.lucene.util.fst
Class ByteSequenceOutputs

    java.lang.Object
      org.apache.lucene.util.fst.Outputs<BytesRef>
          org.apache.lucene.util.fst.ByteSequenceOutputs

    public final class ByteSequenceOutputs

extends Outputs<BytesRef>

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

WARNING: This API is experimental and might change in incompatible ways in the next release.

Method Summary
`BytesRef` `add(BytesRef prefix, BytesRef output)` Eg add("foo", "bar") -> "foobar"
`BytesRef` `common(BytesRef output1, BytesRef output2)` Eg common("foo", "foobar") -> "foo"
`BytesRef` `getNoOutput()` NOTE: this output is compared with == so you must ensure that all methods return the single object if it's really no output
`static ByteSequenceOutputs` `getSingleton()`
`String` `outputToString(BytesRef output)`
`BytesRef` `read(DataInput in)`
`BytesRef` `subtract(BytesRef output, BytesRef inc)` Eg subtract("foobar", "foo") -> "bar"
`void` `write(BytesRef prefix, DataOutput out)`

### common

    public BytesRef common(BytesRef output1,
                           BytesRef output2)

  Description copied from class: `Outputs`
  Eg common("foo", "foobar") -> "foo"

  Specified by:
    `common` in class `Outputs<BytesRef>`

### subtract

    public BytesRef subtract(BytesRef output,
                             BytesRef inc)

  Description copied from class: `Outputs`
  Eg subtract("foobar", "foo") -> "bar"

  Specified by:
    `subtract` in class `Outputs<BytesRef>`

### add

    public BytesRef add(BytesRef prefix,
                        BytesRef output)

  Description copied from class: `Outputs`
  Eg add("foo", "bar") -> "foobar"

  Specified by:
    `add` in class `Outputs<BytesRef>`

### write

    public void write(BytesRef prefix,
                      DataOutput out)
               throws IOException

  Specified by:
    `write` in class `Outputs<BytesRef>`

    `IOException`

### getNoOutput

    public BytesRef getNoOutput()

  Description copied from class: `Outputs`
  NOTE: this output is compared with == so you must ensure that all methods return the single object if it's really no output

  Specified by:
