Method: JSONValidate.validate

Defined in:
lib/json_validate.rb

.validate(json, validator = nil, path = [], &block) ⇒ Object

Validate the parsed JSON object with the validator validator can be a hash or an array

e.g. {id: Fixnum, subject: String, message: String, receipients: [{email: String, name: String}]}
e.g. [String]

This throws a ValidationError if the validation failed. If a block is given, validator is ignored and the block is evaluated as the validator to be used
