Class ComponentResourceSelector

java.lang.Object
  extended by org.apache.tapestry5.services.pageload.ComponentResourceSelector

public final class ComponentResourceSelector
extends Object

Encapsulates the information that is used when locating a template or message catalog associated with a component. The selector is combined with the component class name to locate the other resources. The selector defines one or more axes that are combined with a ComponentResourceLocator implementation to enforce a naming convention for locating resources. The primary axis is Locale (Tapestry 5.2 and earlier used a Locale instance as the selector), but Tapestry 5.3 adds support for additional axes.

Since:
5.3

Returns:
new selector including axis value

getAxis

public <T> T getAxis(Class<T> axisType)
Returns a previously stored axis value, or null if no axis value of the specified type has been stored.
