3 Status of the Java implementation
4 Pending from previous meetings
- Question: what does isAvailable() mean in case of multiple consumers. Do all consumers need to have the same time(s)?
- Leave in for now, review after more implementation, one suggestion of modification bool isAvailable(whosAsking);
Will be discussed later during the meeting, Stef will show an example of using isAvailable(whosAsking);
- We will introduce a boolean argument that indicates whether the component should run in a pull mode (like in OpenMI 1.4) or in loop mode: Discuss component operation mode here - comment from Peter Gijsbers need to be discussed
- "string Validate()" / "bool IsValid(IExchangeItem item)" / "IsAvailable()", etc.
- to be reviewed at this meeting
- When we get loops in the compositions - we have to tell which component will be first! In the new GUI, we will let the user indicate the 'Start up component'.
- IArgument needs a mechanism for identifying the type of argument e.g. File, Path, int double etc Very usful for providing customised GUI functionality
Adrian's proposal is below
namespace OpenMI.Standard { public enum EArgType { String = 0, // default Bool, Int, Double, Path, // presummed to exist and accessable FilePath, // presummed to exist and accessable PathNew, FilePathNew, XML, // Rob: can be used together with a schema for complex argument data MIME, // Rob: might be useful to pass in images, or text documents, etc. } /// <summary> /// The IArgument interface defines a key - value pair. If the property ReadOnly is /// false the value is editable otherwise it is read-only. /// </summary> public interface IArgument : IDescribable { /// <summary> /// Type that string value represents and can be converted to /// </summary> EArgType ValueType { get; } /// <summary> /// The key (string) in key-value pair. /// </summary> string Key {get;} /// <summary> /// <para>The value (double) in key-value pair.</para> /// /// <para>If the ReadOnly property is true and the property is attempted to be changed /// from outside an exception must be thrown.</para> /// </summary> string Value { get; set; } /// <summary> /// Defines whether the Values property may be edited from outside. /// </summary> bool ReadOnly {get;} } }
