# Mixin for the {RailsOps::Operation} class that provides a simple way of
# validation the params hash against a specific schema. It internally uses
# policies for running the validations (see {RailsOps::Mixins::Policies}).
module RailsOps::Mixins::SchemaValidation

module ClassMethods
# Creates a policy to validate the params hash against the given schema. See
# {Schemacop::Validator} for more information on how schemas are built.
#
# Using `policy_chain`, you can control when the validation is performed.
# Per default, validation is done before performing the operation.
#
# @param *args [Array] Parameters to pass at schema initialization
# @param policy_chain [Symbol] The policy chain to perform the schema validation in
# @yield Block to pass at schema initialization
