Method Detail

getClone

HasModelManager getClone()

Clones are used to store the state of actual object at a specific moment. All fields of current object have to be copied to the new clone.Otherwise that may lead to some inconsistencies in actual object history.

Important: Do not use GWT.create() while instantiating the new clone, use new keyword.
Ex: MyTypeToClone clone = new MyTypeToclone();
Rather than: MyTypeToClone clone = GWT.create(MyTypeToclone.class);

Important: While cloning a list, only the list itself has to be a new instance, meaning the content of the list should'nt have to be cloned

Returns:

HasModelManager that is a clone of actual object.

copy

void copy(java.lang.Object object)

Copying a model means change the state of the actual one but setters shouldn't be used while copying fields. Otherwise that may lead to some inconsistencies in actual object history. Use fields directly to copy the passed object :

Ex: this.myField = objectToCopy.getMyField()
Rather than: this.setMyField(objectToCopy.getMyField());

Important: While copying a list from the passed object the actual model list must be replaced by a new list:
Ex:this.dummyModels = new ArrayList();

Important: While copying a field that have a mutable type, the concerned type have to be copied to.
Ex:if (mtocopy.getDummyModel()!=null) this.dummyModel.copy(mtocopy.getDummyModel());

Parameters:

object - The object to copy
