Method Details

getConfigProperties

public List<ProviderConfigProperty> getConfigProperties()

Specified by:

getConfigProperties in interface ConfiguredProvider

skipValidation

protected boolean skipValidation(Object value,
 ValidatorConfig config)

Description copied from class: AbstractSimpleValidator

Decide if validation of individual value should be skipped or not. It should be controlled by AbstractSimpleValidator.IGNORE_EMPTY_VALUE configuration option, see AbstractSimpleValidator.isIgnoreEmptyValuesConfigured(ValidatorConfig).

Specified by:

skipValidation in class AbstractSimpleValidator

Parameters:

value - currently validated we make decision for

config - to look for options in

Returns:

true if validation should be skipped for this value - AbstractSimpleValidator.doValidate(Object, String, ValidationContext, ValidatorConfig) is not called in this case.

See Also:

• AbstractSimpleValidator.doValidate(Object, String, ValidationContext, ValidatorConfig)

doValidate

protected void doValidate(Object value,
 String inputHint,
 ValidationContext context,
 ValidatorConfig config)

Description copied from class: AbstractSimpleValidator

Validate type, format, range of the value etc. Always use ValidationContext.addError(ValidationError) to report error to the user! Can be called multiple time for one validation if input is Collection.

Specified by:

doValidate in class AbstractSimpleValidator

Parameters:

value - to be validated, never null

context - for the validation. Add errors into it.

config - of the validation if provided

See Also:

• AbstractSimpleValidator.skipValidation(Object, ValidatorConfig)

selectRangeErrorMessage

protected String selectRangeErrorMessage(ValidatorConfig config)

Select error message depending on the allowed range interval bound configuration.

validateConfig

public ValidationResult validateConfig(KeycloakSession session,
 ValidatorConfig config)

Description copied from interface: ValidatorFactory

Validates the given validation config.

Implementations can use the KeycloakSession to validate the given ValidatorConfig.

Specified by:

validateConfig in interface ValidatorFactory

Parameters:

session - the KeycloakSession

config - the config to be validated

Returns:

the validation result

convert

protected abstract Number convert(Object value,
 ValidatorConfig config)

Convert input value to instance of Number supported by this validator.

Parameters:

value - to convert

config -

Returns:

value converted to supported Number instance

Throws:

NumberFormatException - if value is not convertible to supported Number instance so MESSAGE_INVALID_NUMBER error is reported.

getMinMaxConfig

protected abstract Number getMinMaxConfig(ValidatorConfig config,
 String key)

Get config value for min and max validation bound as a Number supported by this validator

Parameters:

config - to get from

key - of the config value

Returns:

bound value or null

isFirstGreaterThanToSecond

protected abstract boolean isFirstGreaterThanToSecond(Number n1,
 Number n2)

Compare two numbers of supported type (fed by convert(Object, ValidatorConfig) and getMinMaxConfig(ValidatorConfig, String) )

Parameters:

n1 -

n2 -

Returns:

true if first number is greater than second
