Field Detail

name NEW

protected final java.lang.String name

This constraints' name

It sometimes makes grammatical sense to set a more useful name than the default; while 'at least' makes sense for a number-based constraint, 'after' reads better for date-based constraints.

editorProvider NEW

protected EditorProvider<T> editorProvider

Constructor Detail

SingleValueColumnConstraint

protected SingleValueColumnConstraint(java.lang.String name,
                                      T constraintValue,
                                      EditorProvider<T> editorProvider,
                                      java.lang.String group)

Constructor

Parameters:

name - the name of the constraint.

constraintValue - the value of this constraint to be compared with column values.

editorProvider - the editor provider that generates the appropriate editors for constraints of this type.

group - the group of the constraint for visual grouping when presenting to the user.

Method Detail

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 interface ColumnConstraint<T>

Returns:

the group this constraint belongs to.

getName

public java.lang.String getName()

Description copied from interface: ColumnConstraint

Returns the name of the constraint

Specified by:

getName in interface ColumnConstraint<T>

Returns:

the name of the constraint.

getConstraintValue

public final T getConstraintValue()

Returns the constraint value

Returns:

the constraint value

copy

public abstract SingleValueColumnConstraint<T> copy(T newValue)

subclasses must override to generate new versions of themselves but with new comparison value.

Parameters:

newValue - the new value to compare column values against.

Returns:

a new ColumnConstraint that is the same type as this constraint but with a new comparison value.

getEditor

public ColumnConstraintEditor<T> getEditor(ColumnData<T> 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 interface ColumnConstraint<T>

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.

getConstraintValueString

public java.lang.String getConstraintValueString()

Description copied from interface: ColumnConstraint

Returns the "value" of the constraint in string form

This is used for serializing the constraint.

Specified by:

getConstraintValueString in interface ColumnConstraint<T>

Returns:

the "value" of the constraint in string form.

parseConstraintValue

public ColumnConstraint<T> parseConstraintValue(java.lang.String newValue,
                                                java.lang.Object dataSource)

Description copied from interface: ColumnConstraint

Parses the constraint value string for deserialization purposes.

Specified by:

parseConstraintValue in interface ColumnConstraint<T>

Parameters:

newValue - the value of the constraint in string form.

dataSource - the DataSource from the Table.

Returns:

a new ColumnConstraint

getColumnType

public java.lang.Class<T> getColumnType()

Description copied from interface: ColumnConstraint

Returns the column type that this constraint can be used to filter.

Specified by:

getColumnType in interface ColumnConstraint<T>

Returns:

the column type

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object
