 @Nullable Integer fromIncluding,

 @Nullable Integer toIncluding)

Method Details

init

public void init(@Nullable
 @Nullable Integer fromIncluding,
 @Nullable
 @Nullable Integer toIncluding)

Specified by:

init in interface LengthValidator

getFromIncluding

public Integer getFromIncluding()

Description copied from interface: LengthValidator

Returns the length min value which is valid including this value, or null if none specified.

Specified by:

getFromIncluding in interface LengthValidator

getToIncluding

public Integer getToIncluding()

Description copied from interface: LengthValidator

Returns the length max value which is valid including this value, or null if none specified.

Specified by:

getToIncluding in interface LengthValidator

_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(Validator, 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.

clone

public LengthValidatorImpl clone()
                          throws CloneNotSupportedException

Specified by:

clone in interface Validator

Overrides:

clone in class AbstractValidator

Throws:

CloneNotSupportedException
