module Hyrax
##
# Implements the Fedora objState ontology against the given resource.
#
# Use the provided constants as values for `#status` to set state. The
# boolean methods provide easy checking of state.
#
# We assume that no-state, means none of the three object statuses are
# satisfied. Errors are raised if the `#state` attribute isn't defined.
#
# @see http://fedora.info/definitions/1/0/access/ObjState
#
# @example
# status = ResourceStatus.new(resource: my_resource)
# status.inactive? # => false
#
# my_resource.state = ResourceStatus::INACTIVE
# status = ResourceStatus.new(resource: my_resource)
# status.inactive? # => true
#
class ResourceStatus
ACTIVE = Vocab::FedoraResourceStatus.active.freeze
DELETED = Vocab::FedoraResourceStatus.deleted.freeze
INACTIVE = Vocab::FedoraResourceStatus.inactive.freeze
##
# @!attribute [rw] resource
# @return [#state]
attr_accessor :resource
##
# @param [#state] resource
def initialize(resource:)
self.resource = resource
end
##
# @return [Boolean]
# @raise [NoMethodError] if the resource doesn't have a state attribute
def active?
resource.state == ACTIVE
end
##
# @return [Boolean]
# @raise [NoMethodError] if the resource doesn't have a state attribute
def deleted?
resource.state == DELETED
end
##
# @return [Boolean]
# @raise [NoMethodError] if the resource doesn't have a state attribute
def inactive?
resource.state == INACTIVE
