Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`boolean`	`accepts(T value, TableFilterContext context)`	Compares value against the current constraint value to determine acceptance; true if value satisfies the constraints' value, false otherwise
`default java.lang.String`	`asString()`	Returns a reasonable String version of this constraint useful for debugging.
`default int`	`compareTo(ColumnConstraint<T> other)`	ColumnConstraints are displayed by group and then by name
`java.lang.Class<T>`	`getColumnType()`	Returns the column type that this constraint can be used to filter.
`java.lang.String`	`getConstraintValueString()`	Returns the "value" of the constraint in string form
`default java.lang.String`	`getConstraintValueTooltip()`	returns a description of the constraint suitable for displaying in a tooltip
`ColumnConstraintEditor<T>`	`getEditor(ColumnData<T> columnDataSource)`	Returns a ColumnConstraintEditor which will provide gui components for users to edit the constraint values.
`java.lang.String`	`getGroup()`	Returns a "group" string that is used to logically group column constraints for presentation to the user
`java.lang.String`	`getName()`	Returns the name of the constraint
`ColumnConstraint<T>`	`parseConstraintValue(java.lang.String constraintValueString, java.lang.Object dataSource)`	Parses the constraint value string for deserialization purposes.

- Method Detail
  - accepts
```
boolean accepts(T value,
                TableFilterContext context)
```
    Compares value against the current constraint value to determine acceptance; true if value satisfies the constraints' value, false otherwise
    
    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
  - asString
```
default java.lang.String asString()
```
    Returns a reasonable String version of this constraint useful for debugging.
    
    Returns:
    
    the String representation of this constraint
  - getName
```
java.lang.String getName()
```
    Returns the name of the constraint
    
    Returns:
    
    the name of the constraint.
  - getColumnType
```
java.lang.Class<T> getColumnType()
```
    Returns the column type that this constraint can be used to filter.
    
    Returns:
    
    the column type
  - getEditor
```
ColumnConstraintEditor<T> getEditor(ColumnData<T> columnDataSource)
```
    Returns a ColumnConstraintEditor which will provide gui components for users to edit the constraint values.
    
    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
```
java.lang.String getGroup()
```
    Returns a "group" string that is used to logically group column constraints for presentation to the user
    
    Returns:
    
    the group this constraint belongs to.
  - getConstraintValueTooltip
```
default java.lang.String getConstraintValueTooltip()
```
    returns a description of the constraint suitable for displaying in a tooltip
    
    Returns:
    
    a description of the constraint.
  - getConstraintValueString
```
java.lang.String getConstraintValueString()
```
    Returns the "value" of the constraint in string form
    This is used for serializing the constraint.
    
    Returns:
    
    the "value" of the constraint in string form.
  - parseConstraintValue
```
ColumnConstraint<T> parseConstraintValue(java.lang.String constraintValueString,
                                         java.lang.Object dataSource)
```
    Parses the constraint value string for deserialization purposes.
    
    Parameters:
    
    constraintValueString - the value of the constraint in string form.
    
    dataSource - the DataSource from the Table.
    
    Returns:
    
    a new ColumnConstraint
  - compareTo
```
default int compareTo(ColumnConstraint<T> other)
```
    ColumnConstraints are displayed by group and then by name
    
    Specified by:
    
    compareTo in interface java.lang.Comparable<T>
