Overview

Optimized JSON (Oj), as the name implies was written to provide speed optimized JSON handling.

Oj uses modes to control how object are encoded and decoded. In addition global and options to methods allow additional behavior modifications. The modes are:

  • :strict mode will only allow the 7 basic JSON types to be serialized. Any other Object will raise an Exception.

  • :null mode is similar to the :strict mode except any Object that is not one of the JSON base types is replaced by a JSON null.

  • :object mode will dump any Object as a JSON Object with keys that match the Ruby Object's variable names without the '@' character. This is the highest performance mode.

  • :compat or :json mode is the compatible mode for the json gem. It mimics the json gem including the options, defaults, and restrictions.

  • :rails is the compatibility mode for Rails or Active support.

  • :custom is the most configurable mode.

  • :wab specifically for WAB data exchange.

Constant Summary collapse

Error =

Inherit Error class from StandardError.

Class.new(StandardError)
ParseError =

An Exception that is raised as a result of a parse error while parsing a JSON document.

Class.new(Error)
DepthError =

An Exception that is raised as a result of a path being too deep.

Class.new(Error)
LoadError =

An Exception that is raised if a file fails to load.

Class.new(Error)
MimicError =

An Exception that is raised if there is a conflict with mimicking JSON

Class.new(Error)
CUSTOM_MIMIC_JSON_OPTIONS =

Custom mode can be used to emulate the compat mode with some minor differences. These are the options that setup the custom mode to be like the compat mode.
