range

private final Range<R> range

Constructor Detail

AbstractValidatorRange

public AbstractValidatorRange(Range<R> range)

The constructor.

Parameters:

range - is the Range the value has to be contained in.

Method Detail

getCode

protected String getCode()

Description copied from class: AbstractValidator

This is the default implementation to retrieve the code of this ValueValidator.
ATTENTION:
This default implementation returns the classname of the actual ValueValidator implementation. This strategy is chosen for simplicity when implementing a new validator. To ensure stable codes override this method and return a string constant. This shall at least be done when the name of the class is changed.

Overrides:

getCode in class AbstractValidator<V>

Returns:

the code.

convertValue

protected R convertValue(V value)

Converts the value to the type of the range.

Parameters:

value - is the value to convert.

Returns:

the converted value.

validateNotNull

protected NlsMessage validateNotNull(V value)

Description copied from class: AbstractValueValidator

This method performs the validation in case value is NOT null. This method contains the actual custom logic for the validation. It is therefore designed in a way that makes it most simple to implement custom validators.
ATTENTION:
For internationalization you should not directly return string literals but use NlsMessage instead.

Specified by:

validateNotNull in class AbstractValueValidator<V>

Parameters:

value - is the value to validate.

Returns:

the failure message or null if the the given value is valid.

getProperty

public <P> P getProperty(TypedProperty<P> property)

Description copied from class: AbstractValidator

Gets the value of a property.

Overrides:

getProperty in class AbstractValidator<V>

Type Parameters:

P - the generic type of the requested property.

Parameters:

property - the TypedProperty.

Returns:

the requested value or null if undefined.

hashCode

public int hashCode()

Specified by:

hashCode in class AbstractValidator<V>

equals

public boolean equals(Object obj)

Specified by:

equals in class AbstractValidator<V>
