ReferenceContext Class

아티클

When a ModelBusReference is serialized, the serialized string can be made relative to some context information such as a file path. When the string is deserialized, you can provide the same context or a different context. ReferenceContext is a dictionary that stores the context information. The set of keys and types stored in a context depend on the class of ModelBusAdapter that you use.

Methods

	Name	Description
	Add	Associate a value with a particular key in the reference context.
	Contains	Query whether the specified key has been associated with a value in this context
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Remove	Remove the association between the specified key and its value from the context, if any.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	TryGetValue<T>	Lookup the value associated with a specified key in the context.

Remarks

For Modelbus Adapters that use file paths, use the keys ModelBusReferencePropertySerializer.FilePathSaveContextKey and ModelBusReferencePropertySerializer.FilePathLoadContextKey to index folder names in the ReferenceContext.

For more information, see Integrating Models by using Visual Studio Modelbus.

Examples

To serialize relative to a path:

elementReference.ReferenceContext.Add(
   ModelBusReferencePropertySerializer.FilePathSaveContextKey, 
   currentProjectFilePath);
string serialized = modelBus.SerializeReference(elementReference);

To retrieve the reference from the string:

ReferenceContext context = new ReferenceContext();
context.Add(ModelBusReferencePropertySerializer.FilePathLoadContextKey,
    currentProjectFilePath);
ModelBusReference elementReferenceRestored =
    modelBus.DeserializeReference(serialized, context);

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
