| Method Summary | |
| Object | getValue()
Gets the value to compare with. | | public String | toString()
Returns a string representation of this FieldValueConstraint. |
| getValue | | Object getValue()(Code) | | Gets the value to compare with.
Depending on the field type, the value is of type
String or Number.
If the associated field type is of string type, when used in
combination with the operator LIKE, this may contain the
following wildcard characters as well:
- % for any string
- _ for a single character
|
| toString | | public String toString()(Code) | | Returns a string representation of this FieldValueConstraint.
The string representation has the form
"FieldValueConstraint(inverse:<:inverse>, field:<field>,
casesensitive:<casesensitive>, operator:<operator>,
value:<value>)"
where
- <inverse>is the value returned by
FieldValueConstraint.isInverse isInverse()
- <field> is the field alias returned by
FieldConstraint#getField().getAlias(), or
FieldConstraint#getField().getFieldName()
when the former is null.
- <casesensitive> is the value returned by
FieldConstraint.isCaseSensitive isCaseSensitive()
- <operator> is the value returned by
(@link FieldCompareConstraint#getOperator getOperator()}
- <value> is the value returned by
FieldValueConstraint.getValue getValue()
A string representation of this FieldValueConstraint. |
