Intervals

An interval is a subset of consecutive scale values. DEXi often uses intervals in connection with utility functions, particularly when they are edited or represented by complex rules. The use of intervals can be enabled or disabled in the Scale Editor for each scale individually.

An interval of values is denoted in one of the following ways:

  • ‘*’: the asterisk denotes any value of the corresponding attribute;

  • ‘>=value’: stands for ‘better than or equal to’ value (alternative interpretation: ‘at least as good as’ value);

  • ‘<=value’: ‘worse than or equal to’ value;

  • value1:value2’: denotes the interval between and including the two values.
