| comparesEquality | | boolean comparesEquality()(Code) | | |
| evaluate | | boolean evaluate(Object reference, Object value, boolean ignoreCase)(Code) | | Evaluate this ColumnComparator.
reference is the value entered by the user in the filter definition.
value is the actual value against which the reference should be
compared.
Comparators with needsValue() == true should ignore the reference
value
|
| getOperator | | String getOperator()(Code) | | Return a String representation to be displayed in the UI
|
| needsValue | | boolean needsValue()(Code) | | If this filter does not need a reference value (e.g. for IS NULL)
this method should return true. In that case, the reference
value passed into the
ColumnComparator.evaluate(Object,Object,boolean) method
has to be ignored by the filter.
|
| supportsIgnoreCase | | boolean supportsIgnoreCase()(Code) | | Should return true if this comparator supports the ignoreCase
parameter in the
ColumnComparator.evaluate(Object,Object,boolean) method.
The value returned by this method will be used when building the GUI
for defining a filter.
|
| supportsType | | boolean supportsType(Class valueClass)(Code) | | Check if this comparator can be applied to the given class
|
| validateInput | | boolean validateInput(Object input)(Code) | | Validate the input whether this comparator
can actually deal with the value
