Detailed Description

Type definition for enumeration types.

This class expects that PARAM_TYPE is an array of allowed values. Subclasses may override getEnumValues() to determine the allowed values differently.

The result from validate() is one of the defined values.

Failure codes:

'badvalue': The value is not a recognized value. No data.

Additional codes may be generated when using certain PARAM constants. See the constants' documentation for details.

Since: 1.34

Stability: unstable

Member Function Documentation

◆ checkSettings()

Wikimedia\ParamValidator\TypeDef\EnumDef::checkSettings	(	string	$name,
			$settings,
		array	$options,
		array	$ret )

Validate a parameter settings array.

This is intended for validation of parameter settings during unit or integration testing, and should implement strict checks.

The rest of the code should generally be more permissive.

See also: ParamValidator::checkSettings()

Stability: stable: to override

Parameters

string	$name	Parameter name
array \| mixed	$settings	Default value or an array of settings using PARAM_* constants.
array	$options	Options array, passed through to the TypeDef and Callbacks.
array	$ret	'issues': (string[]) Errors detected in $settings, as English text. If the settings are valid, this will be the empty array. Keys on input are ParamValidator constants, allowing the typedef to easily override core validation; this need not be preserved when returned. 'allowedKeys': (string[]) ParamValidator keys that are allowed in `$settings`. 'messages': (MessageValue[]) Messages to be checked for existence.

Returns: array $ret, with any relevant changes.

◆ getEnumValues()

Wikimedia\ParamValidator\TypeDef\EnumDef::getEnumValues	(		$name,
		array	$settings,
		array	$options )

Get the values for enum-like parameters.

This is primarily intended for documentation and implementation of PARAM_ALL; it is the responsibility of the TypeDef to ensure that validate() accepts the values returned here.

Stability: stable: to override

Parameters

string	$name	Parameter name being validated.
array	$settings	Parameter settings array.
array	$options	Options array.

Returns: array|null All possible enumerated values, or null if this is not an enumeration.

◆ getEnumValuesForHelp()

Wikimedia\ParamValidator\TypeDef\EnumDef::getEnumValuesForHelp	(		$name,
		array	$settings,
		array	$options )

protected

Return enum values formatted for the help message.

Parameters

string	$name	Parameter name being described.
array	$settings	Parameter settings array.
array	$options	Options array.

Returns: (MessageParam|string)[]

◆ getHelpInfo()

Wikimedia\ParamValidator\TypeDef\EnumDef::getHelpInfo	(		$name,
		array	$settings,
		array	$options )

Describe parameter settings in human-readable format.

Keys in the returned array should generally correspond to PARAM constants.

If relevant, a MessageValue describing the type itself should be returned with key ParamValidator::PARAM_TYPE.

The default messages for other ParamValidator-defined PARAM constants may be suppressed by returning null as the value for those constants, or replaced by returning a replacement MessageValue. Normally, however, the default messages should not be changed.

MessageValues describing any other constraints applied via PARAM constants specific to this class should also be returned.

Stability: stable: to override

Parameters

string	$name	Parameter name being described.
array	$settings	Parameter settings array.
array	$options	Options array.

Returns: (MessageValue|null)[]

◆ getParamInfo()

Wikimedia\ParamValidator\TypeDef\EnumDef::getParamInfo	(		$name,
		array	$settings,
		array	$options )

Describe parameter settings in a machine-readable format.

Keys should be short strings using lowercase ASCII letters. Values should generally be values that could be encoded in JSON or the like.

This is intended to handle PARAM constants specific to this class. It generally shouldn't handle constants defined on ParamValidator itself.

Stability: stable: to override

Parameters

string	$name	Parameter name.
array	$settings	Parameter settings array.
array	$options	Options array.

Returns: array

◆ sortEnumValues()

Wikimedia\ParamValidator\TypeDef\EnumDef::sortEnumValues	(	string	$name,
		array	$values,
		array	$settings,
		array	$options )

protected

Sort enum values for help/param info output.

Parameters

string	$name	Parameter name being described.
string[]	$values	Values being sorted
array	$settings	Parameter settings array.
array	$options	Options array.

Returns: string[]

Definition at line 192 of file EnumDef.php.

◆ stringifyValue()

Wikimedia\ParamValidator\TypeDef\EnumDef::stringifyValue	(		$name,
			$value,
		array	$settings,
		array	$options )

Convert a value to a string representation.

This is intended as the inverse of getValue() and validate(): this should accept anything returned by those methods or expected to be used as PARAM_DEFAULT, and if the string from this method is passed in as client input or PARAM_DEFAULT it should give equivalent output from validate().

Parameters

string	$name	Parameter name being converted.
mixed	$value	Parameter value being converted. Do not pass null.
array	$settings	Parameter settings array.
array	$options	Options array.

Returns: string|null Return null if there is no representation of $value reasonably satisfying the description given.

References Wikimedia\ParamValidator\ParamValidator\implodeMultiValue().

◆ validate()

Wikimedia\ParamValidator\TypeDef\EnumDef::validate	(		$name,
			$value,
		array	$settings,
		array	$options )

Validate the value.

When ParamValidator is processing a multi-valued parameter, this will be called once for each of the supplied values. Which may mean zero calls.

When getValue() returned null, this will not be called.

Parameters

string	$name	Parameter name being validated.
mixed	$value	Value to validate, from getValue().
array	$settings	Parameter settings array.
array	$options	Options array. Note the following values that may be set by ParamValidator: is-default: (bool) If present and true, the value was taken from PARAM_DEFAULT rather that being supplied by the client. values-list: (string[]) If defined, values of a multi-valued parameter are being processed (and this array holds the full set of values).

Returns: mixed Validated value

Exceptions

ValidationException if the value is invalid

Member Data Documentation

◆ PARAM_DEPRECATED_VALUES

const Wikimedia\ParamValidator\TypeDef\EnumDef::PARAM_DEPRECATED_VALUES = 'param-deprecated-values'

(array) Associative array of deprecated values.

Keys are the deprecated parameter values. Value is one of the following:

null: Parameter isn't actually deprecated.
true: Parameter is deprecated.
MessageValue: Parameter is deprecated, and this message (converted to a DataMessageValue) is used in place of the default for passing to $this->failure().

Note that this does not add any values to the enumeration, it only documents existing values as being deprecated.

Failure codes: (non-fatal)

'deprecated-value': A deprecated value was encountered. No data.
