invalid()
invalid(string|array|null $field = null, mixed|null $value = null, boolean $overwrite = false) : $this|mixed
Sets a field as invalid and not patchable into the entity.
This is useful for batch operations when one needs to get the original value for an error message after patching. This value could not be patched into the entity and is simply copied into the _invalid property for debugging purposes or to be able to log it away.
Parameters
| string|array|null | $field | The field to get invalid value for, or the value to set. |
| mixed|null | $value | The invalid value to be set for $field. |
| boolean | $overwrite | Whether or not to overwrite pre-existing values for $field. |
