Description copied from interface: ColumnConstraintEditor

If the editor contains and invalid value, this message should indicate why the value is invalid. Only called if hasValidValue() returns false.

Returns:

an error message, or an empty string if no error

getValueFromComponent

protected ColumnConstraint<T> getValueFromComponent()

Description copied from class: AbstractColumnConstraintEditor

Get the constraints' new value from the editor component. This expects the UI to have been constructed.

Specified by:

getValueFromComponent in class AbstractColumnConstraintEditor<T>

Returns:

the value

• AbstractColumnConstraintEditor.getValue()

buildInlineEditorComponent

protected Component buildInlineEditorComponent()

Description copied from class: AbstractColumnConstraintEditor

Delegate the construction of the inline editor component.

Specified by:

buildInlineEditorComponent in class AbstractColumnConstraintEditor<T>

Returns:

the editors inline component

• AbstractColumnConstraintEditor.getInlineComponent()

updateEditorComponent

protected void updateEditorComponent()

Description copied from class: AbstractColumnConstraintEditor

Indicates to subclasses that the constraint has changed, and the user interface needs to be updated to reflect the new state.

Specified by:

updateEditorComponent in class AbstractColumnConstraintEditor<T>

updateInfoMessage

protected void updateInfoMessage(boolean isValid)

Specified by:

updateInfoMessage in class AbstractColumnConstraintEditor<T>

checkEditorValueValidity

protected boolean checkEditorValueValidity()

Description copied from class: AbstractColumnConstraintEditor

Template method that subclasses must implement. This class will call this method whenever the value changes so that the validity state is updated.

Only called when the editor component has been constructed and UI elements are defined.

Specified by:

checkEditorValueValidity in class AbstractColumnConstraintEditor<T>

Returns:

true if the UI defines a valid value, false otherwise
