Documentation

There are the following access modes for table types:

  • Standard table
    The key access to a standard table uses a linear search. Index operations should normally be used for accessing.
  • Sorted table
    A sorted table is always kept sorted internally. The key access uses a binary search. If the key is not unique, the operation is on the entry with the lowest index.
  • Hash table
    The table is managed internally with a hash procedure. In contrast to standard tables and sorted tables, you cannot access hash tables with an index. All entries must have a unique key.

You can also define a generic table type with generic access modes:

  • Index table
    An index table can be a standard table or a sorted table. Index access is allowed for such tables.
  • Any table (access mode not specified)
    Any table can be a standard table, a sorted table or a hash table. The valid operations for such a table are the set of all valid operations for the different access modes. You cannot access tables of this type with an index.
