Config Validator

Validators ensure that the given value fulfills the specified condition.

Validators can be either used on their own or in a possibly nested Validator Group structure.

Validators are used to validate configuration Data Types.

Model

Validator can be used as a plain Validator or as Validator Group. They are interchangeable.

Validator

attribute	supported data types	description
equal [mixed]	bool, enum, hex, ipv4, ipv6, mac6, number, password, string	An array holding the values of which one must be matched.
notEqual [mixed]	bool, enum, hex, ipv4, ipv6, mac6, number, password, string	An array holding the values of which none must be matched.
min number|hex	number, hex	The lowest valid value
max number|hex	number, hex	The highest valid value
greaterOrEqual string|Reference Compare	number, hex, ipv4	Reference Compare object or the value must be greater then or equal to the value held in the field identified by the supplied SEID. This validator should always be used in opposition with lessOrEqual.
lessOrEqual string|Reference Compare	number, hex, ipv4	Reference Compare object or the value must be less then or equal to the value held in the field identified by the supplied SEID. This validator should always be used in opposition with greaterOrEqual.
minLength unsigned int	string	The minimal valid length of the string
maxLength unsigned int	string	The maximal valid length of the string
regexp string	string	The regular expression the value must match
maxRows unsigned int	table	The maximal allowed number of rows.
minRows unsigned int	table	The minimal allowed number of rows.
unique [string]	table	Checks that the value is unique within the specified columns. Uniqueness is checked for each column independently, multi-column constraints are not supported.

Reference Compare

For validating with lessOrEqual or greaterOrEqual when a minimal difference between values is required, the validator can be defined as an object.

attribute	description
referenced_seid* seid	The field against which to compare.
offset* number|hex	The minimal required difference between the numbers.

Example

The given number must be 20 or greater.

{ "min": 20 }

Validator Group

attribute	description
operator* '&&'|'||'	Defines the logical relationship between groups in the validators array
validators* [Validator]	The validator array

Example

The given number must be at least 5 and at most 10 or be 20 or larger.

{
  "operator": "||",
  "validators": [
    {
      "operator": "&&",
      "validators": [
        { "min": 5 },
        { "max": 10 }
      ]
    },
    { "min": 20 },
  ]
}
