question: protected boolean isLeaf ( ) { Set < Node > allDeps = getDependencies ( DependencyKind . BOUND , DependencyKind . STUCK ) ; if ( allDeps . isEmpty ( ) ) return true ; for ( Node n : allDeps ) { if ( n != this ) { return false ; } } return true ; }
target:  Is this node a leaf? This means either the node has no dependencies, or it just has self-dependencies.
