Constructor Detail
Binding
Binding(DataBinder binder, Component comp, String attr, String expr, LinkedHashSet loadWhenEvents, Set saveWhenEvents, String access, String converter)(Code)
Constrcutor to form a binding between UI component and backend data bean.
Parameters:
  binder - the associated Data Binder.
Parameters:
  comp - The concerned component
Parameters:
  attr - The component attribute
Parameters:
  expr - The bean expression.
Parameters:
  loadWhenEvents - The event set when to load data.
Parameters:
  saveWhenEvents - The event set when to save data.
Parameters:
  access - In the view of UI component: "load" load only, "both" load/save, "save" save only when doing data binding. null means using the default access natural of the component. e.g. Label.expr is "load", but Textbox.expr is "both".
Parameters:
  converter - The converter class used to convert classes between component attribute and the associated bean expression. null means using the default class conversion method.
