========================

.. _`Flow Validator Reference: AggregateBoundaryValidator`:

AggregateBoundaryValidator
--------------------------

A validator which will not validate Aggregates that are lazy loaded and uninitialized.
Validation over Aggregate Boundaries can hence be forced by making the relation to
other Aggregate Roots eager loaded.

Note that this validator is not part of the public API and you should not use it manually.

Checks if the given value is valid according to the validator, and returns
the Error Messages object which occurred. Will skip validation if value is
an uninitialized lazy loading proxy.

.. note:: A value of NULL or an empty string ('') is considered valid




.. _`Flow Validator Reference: AlphanumericValidator`:

AlphanumericValidator
---------------------

Validator for alphanumeric strings.

The given $value is valid if it is an alphanumeric string, which is defined as [[:alnum:]].

.. note:: A value of NULL or an empty string ('') is considered valid




.. _`Flow Validator Reference: BooleanValueValidator`:

BooleanValueValidator
---------------------

Validator for a specific boolean value.

Checks if the given value is a specific boolean value.

.. note:: A value of NULL or an empty string ('') is considered valid



Arguments
*********

* ``expectedValue`` (boolean, *optional*): The expected boolean value




.. _`Flow Validator Reference: CollectionValidator`:

CollectionValidator
-------------------

A generic collection validator.

Checks for a collection and if needed validates the items in the collection.
This is done with the specified element validator or a validator based on
the given element type and validation group.

Either elementValidator or elementType must be given, otherwise validation
will be skipped.

.. note:: A value of NULL or an empty string ('') is considered valid



Arguments
*********

* ``elementValidator`` (string, *optional*): The validator type to use for the collection elements

* ``elementValidatorOptions`` (array, *optional*): The validator options to use for the collection elements

* ``elementType`` (string, *optional*): The type of the elements in the collection

* ``validationGroups`` (string, *optional*): The validation groups to link to




.. _`Flow Validator Reference: CountValidator`:

CountValidator
--------------

Validator for countable things

The given value is valid if it is an array or \Countable that contains the specified amount of elements.

.. note:: A value of NULL or an empty string ('') is considered valid



Arguments
*********

* ``minimum`` (integer, *optional*): The minimum count to accept

* ``maximum`` (integer, *optional*): The maximum count to accept




.. _`Flow Validator Reference: DateTimeRangeValidator`:

DateTimeRangeValidator
----------------------

Validator for checking Date and Time boundaries

Adds errors if the given DateTime does not match the set boundaries.

latestDate and earliestDate may be each <time>, <start>/<duration> or <duration>/<end>, where <duration> is an
ISO 8601 duration and <start> or <end> or <time> may be 'now' or a PHP supported format. (1)

In general, you are able to provide a timestamp or a timestamp with additional calculation. Calculations are done
as described in ISO 8601 (2), with an introducing "P". P7MT2H30M for example mean a period of 7 months, 2 hours
and 30 minutes (P introduces a period at all, while a following T introduces the time-section of a period. This
is not at least in order not to confuse months and minutes, both represented as M).
A period is separated from the timestamp with a forward slash "/". If the period follows the timestamp, that
period is added to the timestamp; if the period precedes the timestamp, it's subtracted.
The timestamp can be one of PHP's supported date formats (1), so also "now" is supported.

Use cases:

If you offer something that has to be manufactured and you ask for a delivery date, you might assure that this
date is at least two weeks in advance; this could be done with the expression "now/P2W".
If you have a library of ancient goods and want to track a production date that is at least 5 years ago, you can
express it with "P5Y/now".

Examples:

If you want to test if a given date is at least five minutes ahead, use
  earliestDate: now/PT5M
If you want to test if a given date was at least 10 days ago, use
  latestDate: P10D/now
If you want to test if a given date is between two fix boundaries, just combine the latestDate and earliestDate-options:
  earliestDate: 2007-03-01T13:00:00Z
  latestDate: 2007-03-30T13:00:00Z
