Implement basic infrastructure for optimization networks

[swagner]

To Do:

• check handling of locked and read-only state of controls

Topics for Discussion:

• design in general
  • how much logic should be included in a port?
  • problem of generic view types
  • exception handling
  • how to bridge the gap between internal and external ports of networks?
  • declarative definition of results
• port-to-port communication
  • clone value?
  • how to switch threads?
  • should ports propagate their values immediately when they are connected?
• data types
  • POCOs vs. IItems
  • generic vs. non-generic types (e.g. ports)
• AlgorithmNode
  • port updates due to result changes (speed, events)

Results of code review with abeham, mkommend, ascheibe:

• check item descriptions and item images (done)
• check access modifiers (public, protected, private)
• change formatting of multi-line LINQ queries (indentation, points should be at the beginning and not at the end of a line) (done)
• IEntity, Entity
  • rename to INetworkItem and NetworkItem (done)
  • remove the Path property and the PathChanged event (done)
  • add a generic way for error handling to propagate errors through multiple network items (e.g. if a node contains a port with an invalid port connection, the node itself should also show an error)
• Node
  • should be abstract (done)
  • add additional checks in the setter of the Parent property to reduce the danger of invalid values when the setter is accidentally called directly
• IGenericNode, GenericNode (done)
  • rename to IUserDefinedNode and UserDefinedNode or find an even better name (done)
  • should be sealed (done)
• Network (done)
  • should be abstract (done)
  • Nodes should not be changeable by default (similar to Ports in Node) (done)
  • derive sealed IUserDefinedNetwork and UserDefinedNetwork (find an even better name?) (done)
• Port
  • add additional checks in the setter of the Parent property to reduce the danger of invalid values when the setter is accidentally called directly
• ParameterizedPort (done)
  • Parameters should not be changeable by default (similar to Ports in Node) (done)
• IGenericPort, GenericPort (done)
  • rename to IMessagePort and MessagePort (done)
  • only store the last message and not all messages (done)
  • refactor CanConnectToPort as there might occur a NullReferenceException and to avoid code duplication (done)
  • refactor PrepareMessage to avoid code duplication (done)
  • remove IConnectedPort (done)
  • add IConnectablePort to enable generic port connection handling in the GUI (done)
  • IMessagePort should implement IParameterizedPort and IConnectablePort (done)
• PortParameter
  • add additional checks in the setter of the Parent property to reduce the danger of invalid values when the setter is accidentally called directly
• PortParameterType (done)
  • remove None (done)
• AlgorithmNode (done)
  • replace algorithm.Runs.Clear() and algorithm.Prepare() by algorithm.Prepare(true) (done)
• HookOperator (done)
  • check if there is an operator parameter for each port parameter (done)
  • clone Port by default and prevent cloning when necessary by registering the port as its own clone (e.g. in AlgorithmNode when cloning the algorithm before its execution) (done)
• EntityView
  • increase the gap between the name label and the name textbox so that there is enough space to show the error icon if the name is not valid
