◆ temporal_max_header_size()

uint32_t temporal_max_header_size ( void  )

Bounding box operators for temporal types.

The bounding box of temporal values are

  • a Span for temporal Boolean and temporal text values
  • a TBox for temporal integers and floats, where the x coordinate is for the value dimension and the t coordinate is for the time dimension. The following operators are defined: overlaps, contains, contained, same, and adjacent.

The operators consider as many dimensions as they are shared in both arguments: only the value dimension, only the time dimension, or both the value and the time dimensions.

Return the size in bytes to read from toast to get the basic information from a temporal: Temporal struct (i.e., TInstant, TSequence, or TSequenceSet) and bounding box size
