Andy Seaborne created JENA-1107: ----------------------------------- Summary: Rework jena-base lib.Tuple Key: JENA-1107 URL: https://issues.apache.org/jira/browse/JENA-1107 Project: Apache Jena Issue Type: Improvement Reporter: Andy Seaborne Assignee: Andy Seaborne Priority: Minor
Tuples, which are immutable, value-equality fixed length sequences of instances of the same type, accessed by index. They are like {{T[]}} but immutable, with .equals based on contents, could be improved to work independently of their original use in TDB. Proposal: # Make Tuple an interface (simpler than current), with special implementations for low number of elements. # {{ColumnMap}} ==> {{TupleMap}} and sort out the naming as much as possible to use as a way to manage index mapping, not just rewriting Tuples. An intermediate step is to move {{ColumnMap}} into TDB. This is not a proposal to add it to {{Triple}} or {{Quad}}. {{Triple}} is not the same as a 3-length {{Tuple<Node>}}. Triple elements are accessed by name (`getSubject` etc) not index. SPO is just one possible order in which to think about triples but it has no special status. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
