antiaction-common-json

Java JSON library

A compact library to un/-marshall JSON streams to/from objects/representations.

Usage

• JSON stream <> JSON structure <> Java objects.
• JSON stream <> Java objects.

Using JSON structures is more flexible depending on ones requirements. Converting directly between streams and objects is the fastest.

Support

Java types supported:

• Null
• Boolean/boolean
• Integer/int
• Long/long
• Float/float
• Double/double
• BigInteger
• BigDecimal
• String
• Byte[]/byte[]
• Array[<..>]

And partial support for

• Byte/byte
• Character/char
• java.util.Date
• java.sql.Timestamp
• List<..>
• Map<String, ..>
• Set<..>

Roadmap

• Check how json values not mapped are handled.
• Omit null values from json output.
• Add full support for Set<..>, Map<..> and List<..>.
• Add support for converters in JSON stream <> Java objects (un)marshalling.
• Add full support for more primitive types and their object counterparts.
• Improve code coverage.
