See: Description

Class Summary
Class | Description
--- | ---
BytesToNameCanonicalizer | A caching symbol table implementation used for canonicalizing JSON field names (as `Name`s which are constructed directly from a byte-based input source).
CharsToNameCanonicalizer | This class is a kind of specialized type-safe Map, from char array to String value.
Name | Base class for tokenized names (key strings in objects) that have been tokenized from byte-based input sources (like `InputStream`.
Name1 | Specialized implementation of PName: can be used for short Strings that consists of at most 4 bytes.
Name2 | Specialized implementation of PName: can be used for short Strings that consists of 5 to 8 bytes.
Name3 | Specialized implementation of PName: can be used for short Strings that consists of 9 to 12 bytes.
NameN | Generic implementation of PName used for "long" names, where long means that its byte (UTF-8) representation is 13 bytes or more.
