Detailed Description

Auxiliary structure used to decode Array data types.

After the dimensions information we have the following structure:

  • lower bnds: lower boundary of each dimension (C array of int)
  • null bitmap: bitmap showing locations of nulls (OPTIONAL)
  • actual data: whatever is the stored data.
    Individual items in the array are aligned as specified by the array element type. They are stored in row-major order (last subscript varies most rapidly).
