Code assemblers

Code assemblers are a thin layer above zend-code. There are a lot of built-in assemblers but it is also possible to create your own assembler to generate the code you want to add to the generated SOAP types.

Built-in assemblers

ClassMapAssembler

The ClassMapAssembler is activated by default and is used during the generate:classmap command.

Example output:

<?php

use Phpro\SoapClient\Soap\ClassMap\ClassMapCollection;
use Phpro\SoapClient\Soap\ClassMap\ClassMap;

new ClassMapCollection([
        new ClassMap('HelloWorldRequest', \HelloWorldRequest::class),
        new ClassMap('HelloWorldResponse', \HelloWorldResponse::class),
        new ClassMap('Greeting', \Greeting::class),
]);

ConstructorAssembler

The `ConstructorAssembler can be used to add a constructor with all the class properties to the generated class.

Example output:

    /**
     * Constructor
     *
     * @var string $prop1
     * @var int $prop2
     */
    public function __construct($prop1, $prop2)
    {
        $this->prop1 = $prop1;
        $this->prop2 = $prop2;
    }

FluentSetterAssembler

The FluentSetterAssembler will add a setter method to the generated class. The method will return the current instance to enable chaining.

Example output:

    /**
     * @param string $prop1
     * @return $this
     */
    public function setProp1($prop1)
    {
        $this->prop1 = $prop1;
        return $this;
    }

Generating type-hints is disabled by default, but can be enabled by passing FluentSetterAssemblerOption instance to the constructor with the option withTypeHints set to true.

Example

new FluentSetterAssembler((new FluentSetterAssemblerOptions())->withTypeHints())
    /**
     * @param string $prop1
     * @return $this
     */
    public function setProp1(string $prop1)
    {
        $this->prop1 = $prop1;
        return $this;
    }

FinalClassAssembler

The FinalClassAssembler can be used to mark a generated class as final.

Example output:

final class MyType
{


}

ExtendAssembler

The ExtendAssembler will add a parent class to the generated class.

Example output:

class MyType extends DType
{


}

GetterAssembler

The GetterAssembler will add a getter method to the generated class. For boolean types you can opt to use the 'is' function prefix instead of 'get' by enabling this in the constructor.

Example output:

    /**
     * @return string
     */
    public function getProp1()
    {
        return $this->prop1;
    }

This assembler needs to be constructed with an instance of GetterAssemblerOptions

InterfaceAssembler

The InterfaceAssembler can be used to add a specific interface to the generated class.

Example output:

use Iterator;

class MyType implements Iterator
{


}

IteratorAssembler

The IteratorAssembler can be used for SOAP types that contain a list of another SOAP type. This assembler will make it easy to iterate over the types.

Example output:

use IteratorAggregate;

class MyType implements IteratorAggregate
{

    /**
     * @return \ArrayIterator
     */
    public function getIterator()
    {
        return new \ArrayIterator(is_array($this->prop1) ? $this->prop1 : []);
    }


}

JsonSerializableAssembler

The JsonSerializableAssembler can be used if you want to JSON serialize your SOAP objects. This could be handy for logging JSON serialized request / response data which makes your logs smaller.

Example output:

use JsonSerializable;

class MyType implements JsonSerializable
{

    /**
     * @return array
     */
    public function jsonSerialize()
    {
        return [
            'prop1' => \$this->prop1,
            'prop2' => \$this->prop2,
        ];
    }
}

PropertyAssembler

This PropertyAssembler is enabled by default and is used during the generate:types command.

Example output:

    /**
     * @var string
     */
    private $prop1 = null;

You can adjust the visibility of the property by injecting the visibility in the constructor.

new PropertyAssembler(PropertyGenerator::VISIBILITY_PROTECTED)

Please note that the default ruleset has a visibility of private. If you want to override this, you will have to override all rules by calling Phpro\SoapClient\CodeGenerator\Config\Config::setRuleSet.

RequestAssembler

The RequestAssembler can be used to add the RequestInterface to a generated class.

Example output:

use Phpro\SoapClient\Type\RequestInterface;

class MyType implements RequestInterface
{
}

ResultAssembler

The ResultAssembler can be used to add the ResultInterface to a generated class.

Example output:

use Phpro\SoapClient\Type\ResultInterface;

class MyType implements ResultInterface
{
}

ResultProviderAssembler

The ResultProviderAssembler can be used to add the ResultProviderInterface to a generated class.

Example output:

use Phpro\SoapClient\Type\ResultProviderInterface;
use Phpro\SoapClient\Type\ResultInterface;

class MyType implements ResultProviderInterface
{

    /**
     * @return SomeClass|ResultInterface
     */
    public function getResult() : \Phpro\SoapClient\Type\ResultInterface
    {
        return $this->prop1;
    }
}

It is also possible to add an optional wrapperClass to the constructor. This way, the result is wrapped with a class you specified.

Example output:

namespace MyNamespace;

use Phpro\SoapClient\Type\ResultProviderInterface;
use Phpro\SoapClient\Type\MixedResult

class MyType implements ResultProviderInterface
{

    /**
     * @return MixedResult
     */
    public function getResult() : \Phpro\SoapClient\Type\ResultInterface
    {
        return new MixedResult($this->prop1);
    }


}

SetterAssembler

The SetterAssembler will add a setter method to the generated class.

Example output:

    /**
     * @param string $prop1
     */
    public function setProp1($prop1)
    {
        $this->prop1 = $prop1;
    }

This assembler needs to be constructed with an instance of SetterAssemblerOptions.

TraitAssembler

The TraitAssembler can be used to add a specific trait to the generated class. An alias can be used by passing it in as second argument.

Example output:

use MyTrait;

class MyType
{

    use MyTrait

}

UseAssembler

The UseAssembler can be used to add usage statements to the generated class. Often used internally to add uses for interfaces or traits. An alias can be used by passing it in as second argument.

Example output:

use MyTrait as TraitAlias;

class MyType
{


}

ImmutableSetterAssembler

The ImmutableSetterAssembler generates immutable setters that return a new instance with the new value set. Used to create variations of the same base instance, without modifying the original values.

Example output:

    /**
     * @param string $prop1
     * @return MyType
     */
    public function withProp1($prop1)
    {
        $new = clone $this;
        $new->prop1 = $prop1;

        return $new;
    }

Creating your own Assembler

Creating your own Assembler is pretty easy. The only thing you'll need to do is implementing the AssemblerInterface. You can use the zend-code ClassGenerator and FileGenerator to manipulate your code.

/**
 * Interface AssemblerInterface
 *
 * @package Phpro\SoapClient\CodeGenerator\Assembler
 */
interface AssemblerInterface
{

    /**
     * @param ContextInterface $context
     *
     * @return bool
     */
    public function canAssemble(ContextInterface $context);

    /**
     * Assembles pieces of code.
     *
     * @param ContextInterface $context
     * @throws AssemblerException
     */
    public function assemble(ContextInterface $context);
}

Possible contexts:

  • ClassMapContext: Triggered during the generate:classmap command.
  • TypeContext: Triggered during the generate:types command for every type in the SOAP scheme.
  • PropertyContext: Triggered during the generate:types command for every property in a SOAP type.
