Functions ¶
func CollateJSONEncode ¶
func CompileN1QLExpression ¶
CompileN1QLExpression will take expressions defined in N1QL's DDL statement and compile them for evaluation.
func N1QLTransform ¶
func N1QLTransform( docid []byte, docval qvalue.AnnotatedValue, context qexpr.Context, cExprs []interface{}, encodeBuf []byte, stats *IndexEvaluatorStats) ([]byte, []byte, error)
N1QLTransform will use compiled list of expression from N1QL's DDL statement and evaluate a document using them to return a secondary key as JSON object.
