Method: Oj::Parser.new

Defined in:
ext/oj/parser.c

.new(mode = nil) ⇒ Object

Creates a new Parser with the specified mode. If no mode is provided validation is assumed. Optional arguments can be provided that match the mode. For example with the :usual mode the call might look like Oj::Parser.new(:usual, cache_keys: true).
