Copy/clone constructor sets up details of the parent asset from the template

Parameters:

template - PropertyIteratorBase to copy

Method Details

public int getElementCount()

Return the number of elements in the list.

Returns:

elementCount

cloneElement

protected abstract ElementBase cloneElement(ElementBase template)

Method implemented by a subclass that ensures the cloning process is a deep clone.

Parameters:

template - object to clone

Returns:

new cloned object.

getCachedList

protected abstract List<ElementBase> getCachedList(int cacheStartPointer,
 int maximumSize)
                                            throws PropertyServerException

Method implemented by subclass to retrieve the next cached list of elements.
