Class LengthValidator

java.lang.Object
  wicket.markup.html.form.validation.AbstractValidator
      wicket.markup.html.form.validation.LengthValidator

All Implemented Interfaces:

java.io.Serializable, IValidator

Deprecated. see StringValidator

public class LengthValidator
extends AbstractValidator

Validates that a form component's string value is of a certain min/max length. Validators are constructed by calling the min, max and range static factory methods. For example, LengthValidator.min(6) would return a validator valid only when the input of the component it is attached to is at least 6 characters long. Likewise, LengthValidator.range(3, 5) would only validate a component containing between 3 and 5 characters (inclusive). Depending on which factory is used to create the validator, one or more of the following parameters are added to the error message interpolation:

• min
• max
• length - length of the user input, always present

Gets a length validator object that requires a minimum number of characters.

Parameters:

min - Minimum number of characters

Returns:

Validator object

max

public static final LengthValidator max(int max)

Deprecated.

Gets a length validator object that requires a maximum number of characters.

Parameters:

max - Maximum number of characters

Parameters:

min - Minimum number of characters

max - Maximum number of characters

Returns:

Validator object

validate

public final void validate(FormComponent formComponent)

Deprecated.

Validates that a form component's value is of a certain minimum and/or maximum length.

Parameters:

formComponent - Component to validate

isCheckMax

public final boolean isCheckMax()

Deprecated.

Gets whether the maximum bound should be checked.

the lower bound on valid length

messageModel

protected java.util.Map messageModel(FormComponent formComponent)

Deprecated.

Gets the default variables for interpolation. These are:

• ${min}: the minimal length
• ${max}: the maximum length
• ${length}: the length of the user input

they are only added when the corresponding enabling flag is set.

Overrides:

messageModel in class AbstractValidator

Parameters:

formComponent - form component

Returns:

a map with the variables for interpolation

toString
