Class AttributeDefinition

java.lang.Object
  org.proteios.AttributeDefinition

public class AttributeDefinition
extends Object

An attribute is defined by it's set and get methods. This class defines such attributes. E.g. a String attribute 'name' would be defined as

 AttributeDefinition nameA = new AttributeDefinition(String.class, "Name");
 

a boolean attribute would look like

 AttributeDefinition hiddenA = new AttributeDefinition(Boolean.class, "Hidden",
        "is", "set");
 

meaning that the attribute Hidden is accessible through isHidden() and setHidden(Boolean) methods.
