KeyedCollection.violatesUniqueConstraints

db_constraints keyed keyedcollection KeyedCollection

Checks if the item has any conflicting unique constraints. This is more extensive than $(SRCTAG KeyedCollection.contains).

Precondition: 

assert(items !is null);

Postcondition: 

if (result)
    assert(constraintName !is null && constraintName != "");
else
    assert(constraintName is null);

  1. bool violatesUniqueConstraints(T item, string constraintName)

    (
    in T item
    ,

    out (result) { if (result) assert (constraintName !is null && constraintName != ""); else assert (constraintName is null); }
    if (
