com.jaxio.celerio.util.support.AbstractListHolder<T>

All Implemented Interfaces:

ListHolder<T>

Direct Known Subclasses:

CurrentAndFlatListHolder, SimpleListHolder

public abstract class AbstractListHolder<T extends Named>
extends Object
implements ListHolder<T>

A list holder whose list comes from Iterable. The list may be forked thanks to the except() to exclude some elements based on their name. 'except' feature is convenient for template developers that do not have access to Celerio code. They can do for example: searchAttributes.except('aName').list instead of writing #if statement.
