Class FileProperty

Represents a FileProperty in the data model.

FilePropertys are actually splitted into four different columns in the database. It actually consists of a file name, a file mime type, the size and the actual content of the property. The FileProperty is a kind of wrapper that holds only references to the columns via their name.

The creation of a FileProperty does not create the other properties that hold, e.g. the name of the size. Users of the framework or a UI need to handle the creation of the according properties.

Methods

Validate(ref IList<PropertyValidationMessage>, Boolean)

Validates a ModelElement according to certain rules.

Declaration
protected override void Validate(ref IList<PropertyValidationMessage> messages, bool validateRecursively)
Parameters
Type Name Description
System.Collections.Generic.IList<PropertyValidationMessage> messages

An list of strings that stores that picks up the validation errors of a model element.
System.Boolean validateRecursively

Indicates wheter to validate only the current model element or all its children (recursively) as well.
Overrides
Remarks

The rules the ModelElement is validated against are dependent on the type of ModelElement that is validated. This method can be overridden to provide custom validation behavior for subclasses of ModelElement

When Validate(ref IList<PropertyValidationMessage>, Boolean) is called on a modelelement, the Validate(ref IList<PropertyValidationMessage>, Boolean) method of all children attatched to the modelelemnt are validated recursivly.
