setMultiSelect

public void setMultiSelect(boolean multi)

Set the selection mode of the tree

Specified by:

setMultiSelect in interface SelectorInterface

Specified by:

setMultiSelect in class BaseSelector

Parameters:

multi - Set the selection mode

isMultiSelect

public boolean isMultiSelect()

Get the selection mode of the tree

Specified by:

isMultiSelect in interface SelectorInterface

Overrides:

isMultiSelect in class BaseSelector

isEquivalent

public boolean isEquivalent(Object obj1,
                            Object obj2)

Comparing two user object if they are equivalent. If the user updates the object, the two object will not be the same; however, they should have the same objectID. Using the isPersistedObjectEqual method can check whether the two objects are actually the same object on the database.
