public final class ByteQuadsCanonicalizer extends Object
BytesToNameCanonicalizer
which aims at more localized
memory access due to flattening of name quad data.
Performance improvement modest for simple JSON document data binding (maybe 3%),
but should help more for larger symbol tables, or for binary formats like Smile.Modifier and Type | Method and Description |

in secondary buckets
