case classST_LineMerge(inputExpressions: Seq[Expression]) extends Expression with CodegenFallback with Product with Serializable
Returns a LineString formed by sewing together the constituent line work of a MULTILINESTRING.
Only works for MultiLineString. Using other geometry will return GEOMETRYCOLLECTION EMPTY
If the MultiLineString is can't be merged, the original multilinestring is returned
