Class AbstractRangeValidator<R extends Comparable<? super R> & Serializable,V extends Serializable>

java.lang.Object

org.apache.wicket.behavior.Behavior

org.apache.wicket.validation.validator.AbstractRangeValidator<R,V>

Type Parameters:

R - type of range value

V - type of validatable

All Implemented Interfaces:

Serializable, IComponentAwareEventSink, IComponentAwareHeaderContributor, IClusterable, IValidator<V>

Direct Known Subclasses:

RangeValidator, StringValidator

public abstract class AbstractRangeValidator<R extends Comparable<? super R> & Serializable,V extends Serializable>
extends Behavior
implements IValidator<V>

Base class for validators that check if a given value falls within [min,max] range. If either min or max are null they are not checked.

Resource keys:

• <class.simpleName>.exact if min==max
• <class.simpleName>.range if both min and max are not null
• <class.simpleName>.minimum if max is null
• <class.simpleName>.maximum if min is null

Error Message Variables:

• name: the id of Component that failed
• label: the label of the Component (either comes from FormComponent.labelModel or resource key <form-id>.<form-component-id>
• input: the input value
• minimum: the minimum allowed value
• maximum: the maximum allowed value

Constructor Detail

AbstractRangeValidator

public AbstractRangeValidator(R minimum,
                              R maximum)

Constructor that sets the minimum and maximum values.

Parameters:

minimum - the minimum value

maximum - the maximum value

AbstractRangeValidator

protected AbstractRangeValidator()

Constructor used for subclasses who want to set the range using setRange(Comparable, Comparable)

Method Detail

setRange

protected final void setRange(R minimum,
                              R maximum)

Sets validator range

Parameters:

minimum -

maximum -

validate

public void validate(IValidatable<V> validatable)

Description copied from interface: IValidator

Validates the IValidatable instance. Validation errors should be reported using the IValidatable.error(IValidationError) method.

Specified by:

validate in interface IValidator<V extends Serializable>

Parameters:

validatable - the IValidatable instance being validated

getValue

protected abstract R getValue(IValidatable<V> validatable)

Gets the value that should be validated against the range

Parameters:

validatable -

Returns:

value to validate

getMinimum

public R getMinimum()

Gets the minimum value.

Returns:

minimum value

getMaximum

public R getMaximum()

Gets the maximum value.

Returns:

maximum value

decorate

protected IValidationError decorate(IValidationError error,
                                    IValidatable<V> validatable)

Allows subclasses to decorate reported errors

Parameters:

error -

validatable -

Returns:

decorated error

getMode

public final AbstractRangeValidator.Mode getMode()

Gets validation mode which is determined by whether min, max, or both values are provided

Returns:

validation mode
