 # DigiComp.SettingValidator
 
-This Package allows configuring Validators for your Action-Arguments or domain model properties to be set by a new
-Yaml-File in your Configuration directory.
+This package allows configuring validators with a new configuration type.
 
-Let's imagine you had this action-method:
+## Introduction
 
-    /**
-     * @Flow\Validate(argumentName="order", type="DigiComp.SettingValidator:Settings")
-     * @param Order $order
-     */
-    public function createOrder($order) {...}
+This package provides the `SettingsValidator` which uses the configuration type `Validation` to resolve the validators
+that should be applied to the value. It distinguishes between validators that are applied to the value itself and its
+properties.
 
-Then your Validation.yaml could look like this:
+## Resolving the validation configuration
 
-    Vendor\Package\Domain\Model\Order:
-      # validates the complete object
-      self:
-        'Vendor.Package:SomeOtherValidator': []
-      # validates properties of the object
-      properties:
-        price:
-          NumberRange:
-            maximum: 20
-            minimum: 10
-        customer:
-          'DigiComp.SettingValidator:Settings':
-            name: 'OrderCustomer'
+The `SettingsValidator` has an option `name`. If it is set, the name is used to resolve the validation configuration,
+otherwise the type of the value is used, which is mainly useful for objects where the FQCN is used.
 
-    OrderCustomer:
-      properties:
-        firstName:
-          StringLength:
-            minimum: 3
-            maximum: 20
+### Resolving by option `name`
 
-As you see: Nesting is possible ;) That way you can easily construct flexible structures.
+To resolve the validation configuration by name just use the option `name`.
 
-The SettingsValidator has an optional option: "name" - If you don't give one, it assumes your validation value is an
-object and searches in Validation.yaml for the FQCN.
+```php
+/**
+ * @Flow\Validate(type="DigiComp.SettingValidator:Settings", options={"name"="MyNamedValidator"})
+ * @var MyObject
+ */
+protected MyObject $myObject;
+```
+
+The `SettingsValidator` will search for an entry inside the `Validation.yaml` with that name.
+
+```yaml
+MyNamedValidator:
+  ...
+```
+
+### Resolving by type
+
+To resolve the validation configuration by type just do not set the option `name`.
+
+```php
+/**
+ * @Flow\Validate(type="DigiComp.SettingValidator:Settings")
+ * @var MyObject
+ */
+protected MyObject $myObject;
+```
+
+The `SettingsValidator` will search for an entry inside the `Validation.yaml` with the FQCN of `MyObject`.
+
+```yaml
+My\Package\Domain\Model\MyObject:
+  ...
+```
+
+## The validation configuration
+
+### Difference between `self` and `properties`
+
+`self` contains a map of validators that are applied to the value itself. `properties` contains a map with property
+names of the value you would like to validate and each entry contains a map of validators that are applied to that
+property.
+
+```yaml
+MyNamedValidator:
+  self:
+    ...
+  properties:
+    myProperty1:
+      ...
+    myProperty2:
+      ...
+```
+
+### Configuring a validator
+
+To configure a validator you use the type of the validator as key and the options as entries of that key. If the
+validator has no options or all the default values are used, set an empty map as options.
+
+```yaml
+MyNamedValidator:
+  self:
+    'My.Package:SomeValidator':
+        myOption: "myOptionValue"
+  properties:
+    myProperty1:
+      'My.Package:SomeOtherValidator': {}
+    myProperty2:
+      'My.Package:SomeOtherValidator': {}
+```
+
+### Disable a validator
+
+To disable a validator you need to set the options to `null`.
+
+```yaml
+MyNamedValidator:
+  self:
+    'My.Package:SomeValidator': ~
+```
+
+## Using the `SettingsValidator`
+
+The `SettingsValidator` can be used to reduce the number of `@Flow\Validate` annotations and gives you the possibility
+of overwriting existing validation configurations in other packages.
+
+### Using on properties
+
+Old PHP code:
+
+```php
+/**
+ * @Flow\Validate(type="My.Package:SomeValidator", options={"myOption"="myOptionValue"})
+ * @Flow\Validate(type="My.Package:SomeOtherValidator")
+ * @var MyObject
+ */
+protected MyObject $myObject;
+```
+
+New PHP code:
+
+```php
+/**
+ * @Flow\Validate(type="DigiComp.SettingValidator:Settings", options={"name"="MyNamedValidator"})
+ * @var MyObject
+ */
+protected MyObject $myObject;
+```
+
+New validation configuration:
+
+```yaml
+MyNamedValidator:
+  self:
+    'My.Package:SomeValidator':
+      myOption: "myOptionValue"
+    'My.Package:SomeOtherValidator': {}
+```
+
+### Using on actions
+
+Old PHP code:
+
+```php
+/**
+ * @Flow\Validate(argumentName="myObject", type="My.Package:SomeValidator", options={"myOption"="myOptionValue"})
+ * @Flow\Validate(argumentName="myObject", type="My.Package:SomeOtherValidator")
+ * @param MyObject $myObject
+ */
+public function myAction(MyObject $myObject)
+{
+    ...
+}
+```
+
+New PHP code:
+
+```php
+/**
+ * @Flow\Validate(argumentName="myObject", type="DigiComp.SettingValidator:Settings", options={"name"="MyNamedValidator"})
+ * @param MyObject $myObject
+ */
+public function myAction(MyObject $myObject)
+{
+    ...
+}
+```
+
+New validation configuration:
+
+```yaml
+MyNamedValidator:
+  self:
+    'My.Package:SomeValidator':
+        myOption: "myOptionValue"
+    'My.Package:SomeOtherValidator': {}
+```
+
+### Using inside validator configurations
+
+You can use the `SettingsValidator` inside the validator configuration to easily construct flexible structures.
+
+```yaml
+MyNamedValidator:
+  properties:
+    myProperty1:
+      'DigiComp.SettingValidator:Settings':
+        name: "MyOtherNamedValidator"
+
+MyOtherNamedValidator:
+  self:
+    'My.Package:SomeOtherValidator': {}
+```
+
+## Providing an empty validator
+
+It can be useful to provide an empty validator in code that is used by many projects. By doing so you can make sure that
+a different validation is possible in any project.
+
+```php
+/**
+ * @Flow\Validate(argumentName="myObject", type="DigiComp.SettingValidator:Settings", options={"name"="MyNamedValidator"})
+ * @param MyObject $myObject
+ */
+public function myAction(MyObject $myObject)
+{
+    ...
+}
+```
+
+```yaml
+MyNamedValidator: {}
+```
