Method Detail
-
getName
public java.lang.String getName()
Description copied from interface:ColumnConstraint
Returns the name of the constraint- Specified by:
getName
in interfaceColumnConstraint<java.lang.String>
- Returns:
- the name of the constraint.
-
accepts
public boolean accepts(java.lang.String value, TableFilterContext context)
Description copied from interface:ColumnConstraint
Compares value against the current constraint value to determine acceptance; true if value satisfies the constraints' value, false otherwise- Specified by:
accepts
in interfaceColumnConstraint<java.lang.String>
- Parameters:
value
- the column value to be tested.context
- provides additional information about the the table and its data. This allows the filter to base its decision on information other than just the column value.- Returns:
- true if the column value passes the constraint, false otherwise
-
getColumnType
public java.lang.Class<java.lang.String> getColumnType()
Description copied from interface:ColumnConstraint
Returns the column type that this constraint can be used to filter.- Specified by:
getColumnType
in interfaceColumnConstraint<java.lang.String>
- Returns:
- the column type
-
getEditor
public ColumnConstraintEditor<java.lang.String> getEditor(ColumnData<java.lang.String> columnDataSource)
Description copied from interface:ColumnConstraint
Returns a ColumnConstraintEditor which will provide gui components for users to edit the constraint values.- Specified by:
getEditor
in interfaceColumnConstraint<java.lang.String>
- Parameters:
columnDataSource
- This provides the constraint with access to the column data in the table model as well as the DataProvider of the table (if it has one)- Returns:
- A columnConstraintEditor for editing the constraints value.
-
getGroup
public java.lang.String getGroup()
Description copied from interface:ColumnConstraint
Returns a "group" string that is used to logically group column constraints for presentation to the user- Specified by:
getGroup
in interfaceColumnConstraint<java.lang.String>
- Returns:
- the group this constraint belongs to.
-
getConstraintValueString
public java.lang.String getConstraintValueString()
Description copied from interface:ColumnConstraint
Returns the "value" of the constraint in string formThis is used for serializing the constraint.
- Specified by:
getConstraintValueString
in interfaceColumnConstraint<java.lang.String>
- Returns:
- the "value" of the constraint in string form.
-
parseConstraintValue
public ColumnConstraint<java.lang.String> parseConstraintValue(java.lang.String constraintValueString, java.lang.Object dataSource)
Description copied from interface:ColumnConstraint
Parses the constraint value string for deserialization purposes.- Specified by:
parseConstraintValue
in interfaceColumnConstraint<java.lang.String>
- Parameters:
constraintValueString
- the value of the constraint in string form.dataSource
- the DataSource from the Table.- Returns:
- a new ColumnConstraint
