19 | * Defines configuration for an attribute which may be used as part of a lookups. This includes indicating if the | |
20 | * field is displayed in the lookup criteria or lookup result set, as well as defining information about this field | |
21 | * if it used as part of a range-based lookup. | |
22 | * | |
23 | * <p>The range bounds allows the party executing the lookup against this attribute to enter a value for both ends | |
24 | * (lower and upper bounds) in order to determine if the attribute is "between" those two values.</p> | |
25 | * | |
26 | * <p>Note that an attribute range only makes sense if the {@code DataType} of the attribute is | |
27 | * a date or numerical data type. The consumer of these settings is free to ignore the given | |
28 | * attribute range information if it does not believe it is possible to successfully present a range-based | |
29 | * lookup option based on the data type (or other settings) of the {@code AttributeField}.</p> | |
