Interface CommandField
- All Superinterfaces:
- DisplayField, View
- All Known Implementing Classes:
- CommandFieldBase
- public interface CommandField
- extends DisplayField
Specialization of a display field that represents a user-invokable
application action. A command field is said to be activated when a
user invokes it, thereby sending a request back to the server. Typically,
but not exclusively, implementations of this interface represent the
controls which clients activate in order to invoke request (for example,
buttons and HREF's).
