module Backends::Dummy::Network
Public Instance Methods
Instantiates a new network instance from Occi::Infrastructure::Network. 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
network = Occi::Infrastructure::Network.new network_id = network_create(network) #=> "65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf"
@param network [Occi::Infrastructure::Network] network instance containing necessary attributes @return [String] final identifier of the new network instance
# File lib/backends/dummy/network.rb, line 73 def network_create(network) fail Backends::Errors::IdentifierConflictError, "Instance with ID #{network.id} already exists!" if network_list_ids.include?(network.id) updated = read_network_fixtures << network save_network_fixtures(updated) network.id end
Deletes a specific network 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
network_delete("65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf") #=> true
@param network_id [String] an identifier of a network instance to be deleted @return [true, false] result of the operation
# File lib/backends/dummy/network.rb, line 118 def network_delete(network_id) fail Backends::Errors::ResourceNotFoundError, "Instance with ID #{network_id} does not exist!" unless network_list_ids.include?(network_id) updated = read_network_fixtures.delete_if { |n| n.id == network_id } save_network_fixtures(updated) begin network_get(network_id) false rescue Backends::Errors::ResourceNotFoundError true end end
Deletes all network 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
network_delete_all #=> true mixins = Occi::Core::Mixins.new << Occi::Core::Mixin.new network_delete_all(mixins) #=> true
@param mixins [Occi::Core::Mixins] a filter containing mixins @return [true, false] result of the operation
# File lib/backends/dummy/network.rb, line 95 def network_delete_all(mixins = nil) if mixins.blank? drop_network_fixtures read_network_fixtures.empty? else old_count = read_network_fixtures.count updated = read_network_fixtures.delete_if { |n| (n.mixins & mixins).any? } save_network_fixtures(updated) old_count != read_network_fixtures.count end end
Gets a specific network instance as Occi::Infrastructure::Network. ID given as an argument must match the occi.core.id attribute inside the returned Occi::Infrastructure::Network instance, however it is possible to implement internal mapping to a platform-specific identifier.
@example
network = network_get('65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf') #=> #<Occi::Infrastructure::Network>
@param network_id [String] OCCI identifier of the requested network instance @return [Occi::Infrastructure::Network, nil] a network instance or `nil`
# File lib/backends/dummy/network.rb, line 53 def network_get(network_id) found = read_network_fixtures.to_a.select { |n| n.id == network_id }.first fail Backends::Errors::ResourceNotFoundError, "Instance with ID #{network_id} does not exist!" unless found found end
Gets all network 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::Network instances wrapped in Occi::Core::Resources.
@example
networks = network_list #=> #<Occi::Core::Resources> networks.first #=> #<Occi::Infrastructure::Network> mixins = Occi::Core::Mixins.new << Occi::Core::Mixin.new networks = network_list(mixins) #=> #<Occi::Core::Resources>
@param mixins [Occi::Core::Mixins] a filter containing mixins @return [Occi::Core::Resources] a collection of network instances
# File lib/backends/dummy/network.rb, line 33 def network_list(mixins = nil) if mixins.blank? read_network_fixtures else filtered_networks = read_network_fixtures.to_a.select { |n| (n.mixins & mixins).any? } Occi::Core::Resources.new filtered_networks end end
Gets all network instance IDs, no details, no duplicates. Returned identifiers must correspond to those found in the occi.core.id attribute of Occi::Infrastructure::Network instances.
@example
network_list_ids #=> [] network_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 network instances
# File lib/backends/dummy/network.rb, line 15 def network_list_ids(mixins = nil) network_list(mixins).to_a.map { |n| n.id } end
Partially updates an existing network instance, instance to be updated is specified by network_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 network_partial_update(network_id, attributes, mixins, links) #=> true
@param network_id [String] unique identifier of a network 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/network.rb, line 148 def network_partial_update(network_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 network instance, the network instance in question is identified by a network 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 network_trigger_action("65d4f65adfadf-ad2f4ad-daf5ad-f5ad4fad4ffdf", action_instance) #=> true
@param network_id [String] network instance identifier @param action_instance [Occi::Core::ActionInstance] action to be triggered @return [true, false] result of the operation
# File lib/backends/dummy/network.rb, line 206 def network_trigger_action(network_id, action_instance) case action_instance.action.type_identifier when 'http://schemas.ogf.org/occi/infrastructure/network/action#down' state = 'inactive' when 'http://schemas.ogf.org/occi/infrastructure/network/action#up' state = 'active' else fail Backends::Errors::ActionNotImplementedError, "Action #{action_instance.action.type_identifier.inspect} is not implemented!" end # get existing network instance and set a new state network = network_get(network_id) network.state = state # clean-up and save the new collection network_delete(network.id) updated = read_network_fixtures << network save_network_fixtures(updated) true end
Triggers an action on all existing network 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 network_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/network.rb, line 187 def network_trigger_action_on_all(action_instance, mixins = nil) network_list_ids(mixins).each { |ntwrk| network_trigger_action(ntwrk, action_instance) } true end
Updates an existing network 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
network = Occi::Infrastructure::Network.new network_update(network) #=> true
@param network [Occi::Infrastructure::Network] instance containing updated information @return [true, false] result of the operation
# File lib/backends/dummy/network.rb, line 164 def network_update(network) fail Backends::Errors::ResourceNotFoundError, "Instance with ID #{network.id} does not exist!" unless network_list_ids.include?(network.id) network_delete(network.id) updated = read_network_fixtures << network save_network_fixtures(updated) network_get(network.id) == network end
