Data transfer objects for xervice packages., (*2)
Installation
composer require xervice/data-provider
Configuration
You have to define, where to search for schema files and where to create the DTOs., (*3)
<DataProviders
xmlns="xervice:dataprovider-01"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="xervice:dataprovider-01 http://static.xervice.online/schema/dataprovider.schema.xsd"
>
<DataProvider name="KeyValue">
<DataElement name="Key" type="string"/>
<DataElement name="Value" type="string"/>
</DataProvider>
</DataProviders>
Possible data types:
* int
* string
* bool
* double (= float)
* float
* array
* object
* DataProviderInterface
* DataProviderInterface[]
* AnyNameOfDataProvider, (*4)
With the type "DataProviderInterface" you can set any DataProvider., (*5)
Default values
You can define default values for the following types:
* int
* float
* double
* string
* bool
* array, (*6)
For the type array only an empty array is possible as default.
If you want to define an empty string as default for the type string, you have to set the default to ''., (*7)

<DataProvider name="Default">
<DataElement name="String" default="Text" type="string"/>
<DataElement name="EmptyText" default="''" type="string"/>
<DataElement name="Number" default="5" type="int"/>
<DataElement name="Boolean" default="true" type="bool"/>
<DataElement name="Float" default="1.5" type="float"/>
<DataElement name="List" default="[]" type="array"/>
</DataProvider>
</DataProviders>
Use DTO
$dataProvider = new DataProvider\KeyValueDataProvider();
// Set values
$dataProvider->setKey('keyname');
$dataProvider->setValue('value');
// Get values
$dataProvider->getKey();
// Isset
$dataProvider->hasKey();
// you can also work with arrays
$dataProvider->fromArray([
'Key' => 'keyname',
'Value' => 'value'
]);
// and back to array
$dataArray = $dataProvider->toArray();
Extend and sharing, (*8)
Multiple schame-files with the same DataProvider name will be merged. Also you can choose another DataProvider as type or collection., (*9)

<DataProvider name="KeyValue">
<DataElement name="Key" type="string"/>
<DataElement name="Values" singleton="Value" type="Value[]"/>
</DataProvider>
</DataProviders>
Using, (*10)
<?php
$dto = new KeyValue();
$value = new Value();
$dto->addValue($value);
// List
$dto->setValues(
[
$value
]
);
// Get List
$dto->getValues();
