----------------------------------------------
Summary: Unrolling of collection for ids
Key: TINKERPOP-1345
URL: https://issues.apache.org/jira/browse/TINKERPOP-1345
Project: TinkerPop
Issue Type: Bug
Reporter: Matthias Broecheler
In GraphStep, TinkerPop does this:
{code}
this.ids = (ids.length == 1 && ids[0] instanceof Collection) ? ((Collection)
ids[0]).toArray(new Object[((Collection) ids[0]).size()]) : ids;
{code}
which means that collections are automatically unrolled when there is only one
element. This breaks TP implementations that use collections to represent ids,
for instance, because their id representation has multiple components (like a
primary key in an RDMBS).
