             Summary: Add Path.isEmpty() with a default implementation.
                 Key: TINKERPOP-1542
                 URL: https://issues.apache.org/jira/browse/TINKERPOP-1542
             Project: TinkerPop
          Issue Type: Improvement
          Components: process
    Affects Versions: 3.2.3
            Reporter: Marko A. Rodriguez


We have lots of {{path.size() == 0}} which for {{ImmutablePath}} is a 
recursion. A {{path.isEmpty()}} is a O(1) call. Given how heavily used 
{{ImmutablePath}} is, we should provide {{Path.isEmpty()}} with the following 
default implementation.

{code}
    public default boolean isEmpty() {
        return this.size() == 0;
    }
{code}
