question: protected void deleteTypeVertex ( AtlasVertex instanceVertex , DataTypes . TypeCategory typeCategory , boolean force ) throws AtlasException { switch ( typeCategory ) { case STRUCT : case TRAIT : deleteTypeVertex ( instanceVertex , force ) ; break ; case CLASS : deleteEntities ( Collections . singletonList ( instanceVertex ) ) ; break ; default : throw new IllegalStateException ( "Type category " + typeCategory + " not handled" ) ; } }
target:  Deletes a type vertex - can be entity(class type) or just vertex(struct/trait type)
