Method Detail

isValid

public boolean isValid()

Specified by:

isValid in class DestinationListener

getPropertyValue

public java.lang.Object getPropertyValue(java.lang.Object parent,
                                         boolean getField,
                                         boolean pendingChild)

Description copied from interface: IBinding

Retrieves the current value of the binding given the current object. Use getField = true to force use of the field, rather than the getX method if one exists. Use pendingChild = true for a special case where we are getting the property value of a binding that is part of a reverse binding but where the cached value is up-to-update because we are updating a child remote property.

addBindingListener

public void addBindingListener(java.lang.Object eventObject,
                               IListener listener,
                               int event)

removeBindingListener

public void removeBindingListener(java.lang.Object eventObject,
                                  IListener listener,
                                  int event)

invalidateBinding

public void invalidateBinding(java.lang.Object object,
                              boolean sendEvent,
                              int event,
                              boolean includeParams)

applyBinding

public boolean applyBinding(java.lang.Object obj,
                            java.lang.Object value,
                            IBinding src,
                            boolean refresh,
                            boolean pendingChild)
