/** |
30
|
|
|
* JAXB class definition for <Exclude> tags defining exclusion rules. |
31
|
|
|
* |
32
|
|
|
* The exclude tag has a Name attribute, and either an Equals attribute, a Like |
33
|
|
|
* attribute (corresponding to an SQL LIKE comparison), or a Null attribute. |
34
|
|
|
* The Name attribute defines the column's name in the table, and Equals, |
35
|
|
|
* Like, and Null attributes define the column's excluded value. |
36
|
|
|
* |
37
|
|
|
* The Name attribute is optional if the exclude tag is part of a Column tag's |
38
|
|
|
* exclusion list (the name is then the Column's name). The Name attribute can |
39
|
|
|
* still be included to indicate it should be excluded on the basis of the value |
40
|
|
|
* of another column - however the other column must either be declared as a key |
41
|
|
|
* or as a Column elsewhere in the table definition. This restriction does not |
42
|
|
|
* apply to table exclusions. Any column can be used for a table exclusion. |
43
|
|
|
* |
44
|
|
|
* Excluding empty values is possible by setting the Equals attribute to a blank |
45
|
|
|
* value. The Like attribute requires a value. |
46
|
|
|
* |
47
|
|
|
* Exclude nulls with the optional Null attribute (takes a boolean value). |
48
|
|
|
* |
49
|
|
|
* Inclusions can be defined with the NotLike and NotEquals attribute. In a |
50
|
|
|
* list of <Exclusions> and associated <Exclude> tags, a column's |
51
|
|
|
* value must match at least one NotLike or NotEquals definition if any are |
52
|
|
|
* defined. |
53
|
|
|
* |
54
|
|
|
* Note that column exclusions are not actual SQL exclusions - so some |
55
|
|
|
* differences may apply, for instance in SQL an = comparison may be case |
56
|
|
|
* insensitive depending on the character encoding used on the table, and the |
57
|
|
|
* type of database being queried. |
