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)[]

Stability: stable: to override

stringifyValue ( $name, $value, array $settings, array $options)

Convert a value to a string representation.

validate ( $name, $value, array $settings, array $options)

Validate the value.

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.

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.

Parameters

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

Returns: array

normalizeSettings (array $settings)

Normalize a settings array.

Parameters

array $settings

Returns: array

Detailed Description

Type definition for a floating-point type.

A valid representation consists of:

an optional sign (+ or -)
a decimal number, using . as the decimal separator and no grouping
an optional E-notation suffix: the letter 'e' or 'E', an optional sign, and an integer

Thus, for example, "12", "-.4", "6.022e23", or "+1.7e-10".

The result from validate() is a PHP float.

Failure codes:

'badfloat': The value was invalid. No data.
'badfloat-notfinite': The value was in a valid format, but conversion resulted in infinity or NAN.

Since: 1.34

Stability: unstable

◆ getHelpInfo()

Wikimedia\ParamValidator\TypeDef\FloatDef::getHelpInfo	(		$name,

		array	$options )

◆ stringifyValue()

Wikimedia\ParamValidator\TypeDef\FloatDef::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.

Definition at line 47 of file FloatDef.php.

◆ validate()

Wikimedia\ParamValidator\TypeDef\FloatDef::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
