@Taxonomy(stability=UNCOMMITTED)
public class AttributeResolverHelper
extends org.jvnet.hk2.config.VariableResolver

Helper to resolve attribute configuration values eg ${com.sun.aas.installRoot} once they have already been obtained in "raw" form. If the goal is to fetch the attribute values in already-resolved form, do so directly via @{link AttributeResolver#resolveAttribute}.

Values can be resolved into String, boolean or int.

Example usage:

    HTTPListenerConfig l = ...; // or any AMXConfigProxy sub-interface
    AttributeResolverHelper h = new AttributeResolverHelper( l );
    int port = h.resolveInt( l.getPort() );
    

Alternately, the static method form can be used:

    HTTPListenerConfig l = ...; // or any AMXConfigProxy sub-interface
    int port = AttributeResolverHelper.resolveInt( l, value );
    

The value can also be pre-resolved by calling AttributeResolver
