Method Detail

isDependent

public boolean isDependent()

Whether this object currently belongs or belonged on load to a dependent field.

referenceDependent

public void referenceDependent(KodoStateManager owner,
                               int field,
                               boolean dependent,
                               boolean store)

Mark this object as referenced by the given field. This process occurs on load and flush. If this object was a dereferenced dependent object, clear the dereferenced flag so it is not deleted.

beforeRefresh

public boolean beforeRefresh(boolean refreshAll)

Prepare the instance for refresh

Parameters:

refreshAll - true if this instance is one of a collection of objects being refreshed

Returns:

true if the object needs a refresh, false otherwise

setRemote

public void setRemote(int field,
                      Object value)

Set the given field to the given value. Make the field dirty as if user code set it. Do not delete dependent objects in the field's current value. This method is invoked by the remote package to synch a server-side state manager with remote changes. We do not need to delete dependent instances because they will have been deleted when the field changed on the client side, and those client-side deletes will be transmitted independently.
