Description

AttributeContext.getLocalAttribute usage is to verbose. I think AttributeContext should be improved. This is my currently using BaseViewPreparer.

public abstract class BaseViewPreparer implements ViewPreparer {

    @SuppressWarnings("unchecked")
    protected <T> T getLocalAttribute(String name, AttributeContext attributeContext, T defaultValue){
        Attribute attribute = attributeContext.getLocalAttribute(name);
        if (attribute != null){
            return (T) attribute.getValue();
        }else{
            return defaultValue;
        }
    }

    @Override
    public abstract void execute(Request tilesContext, AttributeContext attributeContext);
}
