Modifier and Type	Method	Description
protected FieldValidationResult	_validate(Object value, Map<String,Object> fields)
boolean	canMergeConstraints()	Tells if the constraint data of this validator can be merged with another instance.

Constructor Details

MandatoryValidatorImpl

public MandatoryValidatorImpl()

Method Details

init

public void init()

Specified by:

init in interface MandatoryValidator

_validate

protected FieldValidationResult _validate(Object value,
 Map<String,Object> fields)
                                   throws IllegalArgumentException

Specified by:

_validate in class AbstractValidator

Throws:

IllegalArgumentException

iNegateMyself

protected boolean iNegateMyself()

Description copied from class: AbstractValidator

If subclass overwrites and returns true then the validate() method won't do it anymore. That's preferred for implementing validators (not groups).

Overrides:

iNegateMyself in class AbstractValidator

See Also:

• AbstractValidator.negateResultIfNeeded(boolean)

canMergeConstraints

public boolean canMergeConstraints()

Description copied from interface: Validator

Tells if the constraint data of this validator can be merged with another instance.

This is validator-type specific. For example a date range validator can, a regex validator obviously cannot.

Specified by:

canMergeConstraints in interface Validator

See Also:

• Validator.mergeConstraints(ch.tocco.nice2.validate.api.validators.Validator, ch.tocco.nice2.validate.api.validators.Validator.MergeMode)

mergeConstraints

public boolean mergeConstraints(Validator validator,
 Validator.MergeMode mode)

Description copied from class: AbstractValidator

Default implementation so that subclasses are only forced to override canMergeConstraints().

Specified by:

mergeConstraints in interface Validator

Overrides:

mergeConstraints in class AbstractValidator

Parameters:

validator - The validator to merge in.

mode - How to merge.

Returns:

true if it was done. This should only fail if canMergeConstraints() says false.

See Also:

• Validator.canMergeConstraints()

getType

public Class<? extends ValueValidator> getType()

Specified by:

getType in interface Validator

Returns:

The class of the implementing class.

isEmptySoIgnore

protected boolean isEmptySoIgnore(Object value)

Description copied from class: AbstractValidator

Subclasses may override this to define what is considered empty, and thus disables the validator.

An example is the string field: an empty input string means "no value given".

Imagine a zipcode field that may be empty (if unknown). A length validator (let's say 4 to 10 characters) must be ignored if no input (empty string) was given.

Overrides:

isEmptySoIgnore in class AbstractValidator

Parameters:

value - The object value as given to validate.

Returns:

True to disable the validator, false to go on.

clone

public MandatoryValidatorImpl clone()
                             throws CloneNotSupportedException

Specified by:

clone in interface Validator

Overrides:

clone in class AbstractValidator

Throws:

CloneNotSupportedException
