internalGetAttribute
Description copied from class:WidgetElement
The goal forWidgetElement.internalGetAttribute(String)
is to share the code ofWidgetElement.hasAttribute(String)
andWidgetElement.getAttribute(String)
and to keep the performance footprint forWidgetElement.hasAttribute(String)
small. This shall be accomplished by:- The method shall only be a lookup for a supplier, no actual computation shall be made.
- The result of the supplier must hold the requirements of the result
of
WidgetElement.getAttribute(String)
. Especially it must not returnnull
. - If the attribute isn't set on the widget, the method must return
null
.
- Overrides:
internalGetAttribute
in classWidgetElement
- Parameters:
attr
- the name of the attribute to look for.- Returns:
- a supplier which will return the actual attribute value or
null
if the attribute isn't set for the widget.
