Method Details

createIntegerValidator

public static DecimalDigitsValidatorImpl createIntegerValidator()

createLongValidator

public static DecimalDigitsValidatorImpl createLongValidator()

createByteValidator

public static DecimalDigitsValidatorImpl createByteValidator()

createShortValidator

public static DecimalDigitsValidatorImpl createShortValidator()

init

public void init(int prePointDigits,
 int decimalDigits)

Specified by:

init in interface DecimalDigitsValidator

getPostPointDigits

public int getPostPointDigits()

Specified by:

getPostPointDigits in interface DecimalDigitsValidator

Returns:

The number of decimal digits maximally allowed.

getPrePointDigits

public int getPrePointDigits()

Specified by:

getPrePointDigits in interface DecimalDigitsValidator

_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.

clone

public DecimalDigitsValidatorImpl clone()
                                 throws CloneNotSupportedException

Specified by:

clone in interface Validator

Overrides:

clone in class AbstractValidator

Throws:

CloneNotSupportedException
