module Backends::Dummy::Storage
Public Instance Methods
Instantiates a new storage instance from Occi::Infrastructure::Storage. ID given in the occi.core.id attribute is optional and can be changed inside this method. Final occi.core.id must be returned as a String. If the requested instance cannot be created, an error describing the problem must be raised, @see Backends::Errors.
@example
storage = Occi::Infrastructure::Storage.new storage_id = storage_create(storage) #=> "65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf"
@param storage [Occi::Infrastructure::Storage] storage instance containing necessary attributes @return [String] final identifier of the new storage instance
# File lib/backends/dummy/storage.rb, line 73 def storage_create(storage) fail Backends::Errors::IdentifierConflictError, "Instance with ID #{storage.id} already exists!" if storage_list_ids.include?(storage.id) updated = read_storage_fixtures << storage save_storage_fixtures(updated) storage.id end
Deletes a specific storage instance, instance to be deleted is specified by an ID, this ID must match the occi.core.id attribute of the deleted instance. If the requested instance cannot be deleted, an error describing the problem must be raised, @see Backends::Errors.
@example
storage_delete("65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf") #=> true
@param storage_id [String] an identifier of a storage instance to be deleted @return [true, false] result of the operation
# File lib/backends/dummy/storage.rb, line 118 def storage_delete(storage_id) fail Backends::Errors::ResourceNotFoundError, "Instance with ID #{storage_id} does not exist!" unless storage_list_ids.include?(storage_id) updated = read_storage_fixtures.delete_if { |s| s.id == storage_id } save_storage_fixtures(updated) begin storage_get(storage_id) false rescue Backends::Errors::ResourceNotFoundError true end end
Deletes all storage instances, instances to be deleted must be filtered by the specified filter, filter (if set) must contain an Occi::Core::Mixins instance. If the requested instances cannot be deleted, an error describing the problem must be raised, @see Backends::Errors.
@example
storage_delete_all #=> true mixins = Occi::Core::Mixins.new << Occi::Core::Mixin.new storage_delete_all(mixins) #=> true
@param mixins [Occi::Core::Mixins] a filter containing mixins @return [true, false] result of the operation
# File lib/backends/dummy/storage.rb, line 95 def storage_delete_all(mixins = nil) if mixins.blank? drop_storage_fixtures read_storage_fixtures.empty? else old_count = read_storage_fixtures.count updated = read_storage_fixtures.delete_if { |s| (s.mixins & mixins).any? } save_storage_fixtures(updated) old_count != read_storage_fixtures.count end end
Gets a specific storage instance as Occi::Infrastructure::Storage. ID given as an argument must match the occi.core.id attribute inside the returned Occi::Infrastructure::Storage instance, however it is possible to implement internal mapping to a platform-specific identifier.
@example
storage = storage_get('65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf') #=> #<Occi::Infrastructure::Storage>
@param storage_id [String] OCCI identifier of the requested storage instance @return [Occi::Infrastructure::Storage, nil] a storage instance or `nil`
# File lib/backends/dummy/storage.rb, line 53 def storage_get(storage_id) found = read_storage_fixtures.to_a.select { |s| s.id == storage_id }.first fail Backends::Errors::ResourceNotFoundError, "Instance with ID #{storage_id} does not exist!" unless found found end
Gets all storage instances, instances must be filtered by the specified filter, filter (if set) must contain an Occi::Core::Mixins instance. Returned collection must contain Occi::Infrastructure::Storage instances wrapped in Occi::Core::Resources.
@example
storages = storage_list #=> #<Occi::Core::Resources> storages.first #=> #<Occi::Infrastructure::Storage> mixins = Occi::Core::Mixins.new << Occi::Core::Mixin.new storages = storage_list(mixins) #=> #<Occi::Core::Resources>
@param mixins [Occi::Core::Mixins] a filter containing mixins @return [Occi::Core::Resources] a collection of storage instances
# File lib/backends/dummy/storage.rb, line 33 def storage_list(mixins = nil) if mixins.blank? read_storage_fixtures else filtered_storages = read_storage_fixtures.to_a.select { |s| (s.mixins & mixins).any? } Occi::Core::Resources.new filtered_storages end end
Gets all storage instance IDs, no details, no duplicates. Returned identifiers must correspond to those found in the occi.core.id attribute of Occi::Infrastructure::Storage instances.
@example
storage_list_ids #=> [] storage_list_ids #=> ["65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf", "ggf4f65adfadf-adgg4ad-daggad-fydd4fadyfdfd"]
@param mixins [Occi::Core::Mixins] a filter containing mixins @return [Array<String>] IDs for all available storage instances
# File lib/backends/dummy/storage.rb, line 15 def storage_list_ids(mixins = nil) storage_list(mixins).to_a.map { |s| s.id } end
Partially updates an existing storage instance, instance to be updated is specified by storage_id. If the requested instance cannot be updated, an error describing the problem must be raised, @see Backends::Errors.
@example
attributes = Occi::Core::Attributes.new mixins = Occi::Core::Mixins.new links = Occi::Core::Links.new storage_partial_update(storage_id, attributes, mixins, links) #=> true
@param storage_id [String] unique identifier of a storage instance to be updated @param attributes [Occi::Core::Attributes] a collection of attributes to be updated @param mixins [Occi::Core::Mixins] a collection of mixins to be added @param links [Occi::Core::Links] a collection of links to be added @return [true, false] result of the operation
# File lib/backends/dummy/storage.rb, line 148 def storage_partial_update(storage_id, attributes = nil, mixins = nil, links = nil) # TODO: impl fail Backends::Errors::MethodNotImplementedError, 'Partial updates are currently not supported!' end
Triggers an action on an existing storage instance, the storage instance in question is identified by a storage instance ID, action is identified by the action.term attribute of the action instance passed as an argument. If the requested action cannot be triggered, an error describing the problem must be raised, @see Backends::Errors.
@example
action_instance = Occi::Core::ActionInstance.new storage_trigger_action("65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf", action_instance) #=> true
@param storage_id [String] storage instance identifier @param action_instance [Occi::Core::ActionInstance] action to be triggered @return [true, false] result of the operation
# File lib/backends/dummy/storage.rb, line 206 def storage_trigger_action(storage_id, action_instance) case action_instance.action.type_identifier when 'http://schemas.ogf.org/occi/infrastructure/storage/action#offline' state = 'offline' when 'http://schemas.ogf.org/occi/infrastructure/storage/action#online' state = 'online' when 'http://schemas.ogf.org/occi/infrastructure/storage/action#backup' state = 'online' when 'http://schemas.ogf.org/occi/infrastructure/storage/action#resize' state = 'online' when 'http://schemas.ogf.org/occi/infrastructure/storage/action#snapshot' state = 'online' else fail Backends::Errors::ActionNotImplementedError, "Action #{action_instance.action.type_identifier.inspect} is not implemented!" end # get existing storage instance and set a new state storage = storage_get(storage_id) storage.state = state # clean-up and save the new collection storage_delete(storage.id) updated = read_storage_fixtures << storage save_storage_fixtures(updated) true end
Triggers an action on all existing storage instance, instances must be filtered by the specified filter, filter (if set) must contain an Occi::Core::Mixins instance, action is identified by the action.term attribute of the action instance passed as an argument. If the requested action cannot be triggered, an error describing the problem must be raised, @see Backends::Errors.
@example
action_instance = Occi::Core::ActionInstance.new mixins = Occi::Core::Mixins.new << Occi::Core::Mixin.new storage_trigger_action_on_all(action_instance, mixin) #=> true
@param action_instance [Occi::Core::ActionInstance] action to be triggered @param mixins [Occi::Core::Mixins] a filter containing mixins @return [true, false] result of the operation
# File lib/backends/dummy/storage.rb, line 187 def storage_trigger_action_on_all(action_instance, mixins = nil) storage_list_ids(mixins).each { |strg| storage_trigger_action(strg, action_instance) } true end
Updates an existing storage instance, instance to be updated is specified using the occi.core.id attribute of the instance passed as an argument. If the requested instance cannot be updated, an error describing the problem must be raised, @see Backends::Errors.
@example
storage = Occi::Infrastructure::Storage.new storage_update(storage) #=> true
@param storage [Occi::Infrastructure::Storage] instance containing updated information @return [true, false] result of the operation
# File lib/backends/dummy/storage.rb, line 164 def storage_update(storage) fail Backends::Errors::ResourceNotFoundError, "Instance with ID #{storage.id} does not exist!" unless storage_list_ids.include?(storage.id) storage_delete(storage.id) updated = read_storage_fixtures << storage save_storage_fixtures(updated) storage_get(storage.id) == storage end
