Class AttributeLOV

java.lang.Object
oracle.ultrasearch.query.AttributeLOV

public class AttributeLOV

extends java.lang.Object

A list of values (LOV) for an attribute.

The values in this list are valid values for attribute queries. For example, for a StringAttribute named Dept, a reasonable LOV may be: Accounting, Research, Sales, Operations. Values are useful in assisting users in formulating a query. But the presence of a value in this list does not necessarily mean any document actually have this values for its attribute.

In addition, this class keeps an optional display name for each value. This is useful in case the attribute has encoded values, such as department number, or country code that are not suitable for direct output.

Since:

9.0.2
