Transform a temporal network point to another subtype

tnpointInst(tnpoint) → tnpointInst

tnpointSeq(tnpoint) → tnpointSeq

tnpointSeqSet(tnpoint) → tnpointSeqSet

SELECT tnpointSeq(tnpoint 'NPoint(1, 0.5)@2001-01-01', 'discrete');
-- {NPoint(1,0.5)@2001-01-01}
SELECT tnpointSeq(tnpoint 'NPoint(1, 0.5)@2001-01-01');
-- [NPoint(1,0.5)@2001-01-01]
SELECT tnpointSeqSet(tnpoint 'NPoint(1, 0.5)@2001-01-01');
-- {[NPoint(1,0.5)@2001-01-01]}

Transform a temporal network point to another interpolation

setInterp(tnpoint, interp) → tnpoint

SELECT setInterp(tnpoint 'NPoint(1,0.2)@2001-01-01','linear');
-- [NPoint(1,0.2)@2001-01-01]
SELECT setInterp(tnpoint '{[NPoint(1,0.1)@2001-01-01], [NPoint(1,0.2)@2001-01-02]}',
  'discrete');
-- {NPoint(1,0.1)@2001-01-01, NPoint(1,0.2)@2001-01-02}

Round the fraction of the temporal network point to the number of decimal places

round(tnpoint,integer) → tnpoint

SELECT round(tnpoint '{[NPoint(1,0.123456789)@2001-01-01, NPoint(1,0.5)@2001-01-02)}', 6);
-- {[NPoint(1,0.123457)@2001-01-01 00:00:00+01, NPoint(1,0.5)@2001-01-02 00:00:00+01)}
