Description
When an application receives instances of ItemPSVI (i.e. ElementPSVI / AttributePSVI) the scope in which they can call methods on these objects is often limited (see PSVIProvider) to start and end element callbacks. If an application wishes to persist the data held by an ItemPSVI beyond this scope it needs to make a copy. To make it easier for users to copy these objects and determine when they need to make a copy I plan on adding the following methods to ItemPSVI:
/**
- Returns a reference to an immutable instance with the same data
- that this instance of <code>ItemPSVI</code> currently has.
*/
public ItemPSVI constant();
/**
- Returns <code>true</code> if this specific instance of
- <code>ItemPSVI</code> is immutable, otherwise <code>false</code>.
*/
public boolean isConstant();
