Description copied from class: PlayPlugin

Called when play need to bind a Java object from HTTP params. When overriding this method, do not call super impl.. super impl is calling old bind method to be backward compatible.

Overrides:

bind in class PlayPlugin

bindBean

public java.lang.Object bindBean(RootParamNode rootParamNode,
                                 java.lang.String name,
                                 java.lang.Object bean)

Called when play need to bind an existing Java object from HTTP params. When overriding this method, DO NOT call the super method, since its default impl is to call the old bind method to be backward compatible.

Overrides:

bindBean in class PlayPlugin
