Types

Available types:

GQLSchema\Types\Scalars\BooleanType
GQLSchema\Types\Scalars\FloatType
GQLSchema\Types\Scalars\IDType
GQLSchema\Types\Scalars\IntegerType
GQLSchema\Types\Scalars\StringType
GQLSchema\Types\InterfaceType

Type modifiers

Type modifiers are used in conjunction with types, add modifier to a type to modify the type in question.

Type	Syntax	Example
Nullable Type	<type>	String
Non-null Type	<type>!	String!
List Type	[<type>]	[String]
List of Non-null Types	[<type>!]	[String!]
Non-null List Type	[<type>]!	[String]!
Non-null List of Non-null Types	[<type>!]!	[String!]!

Example:

$typeModifier = new TypeModifier($nullable = false, $listable = true, $nullableList = false);
$type = new BooleanType($typeModifier);

echo $type; // [bool!]!

Scalar types

Example:

$type = new BooleanType();
echo $type; // Bool

Interface type

Example:

$fields = new FieldCollection();
$fields->add(new Field('name', new StringType()));
$fields->add(new Field('age', new IntegerType()));
$fields->add(new Field('size', new IntegerType()));

$interface = new InterfaceType('Wine', $fields, 'My interface description');

// Yields
"""
My interface description
"""
interface Wine {
  name: String  
  age: Int
  size: Int
}

Object type

Example:

$fields = new FieldCollection();
$fields->add(new Field('name', new StringType()));
$fields->add(new Field('age', new IntegerType()));
$fields->add(new Field('size', new IntegerType()));

$object = new ObjectType('Wine', $fields, 'My object description');

echo $object;

// Yields
type Wine {
  name: String
  age: Int
  size: Int
}

// Add interface

$fields = new FieldCollection();
$fields->add(new Field('name', new StringType()));

$interface = new InterfaceType('Name', $fields);
$object->addInterface($interface);

echo $object;

// Yields
type Wine implements Name {
  name: String
  age: Int
  size: Int
}

Fields

Example:

// Simple
$field = new Field('simpleField', new IntegerType());
echo $field; // simpleField: Int

// With arguments        
$arguments = new ArgumentCollection();
$arguments->add(new Argument(new BooleanType(new TypeModifier($nullable = false)), null, 'booleanArg'));
$arguments->add(new Argument(new IntegerType(new TypeModifier($nullable = false)), null, 'integerArg'));
$arguments->add(new Argument(new StringType(new TypeModifier($nullable = false)), new ValueString('test'), 'stringArg'));

$field = new Field('testField', new IntegerType(new TypeModifier(false)), $arguments);
echo $field; // testField(booleanArg: Boolean!, integerArg: Int!, stringArg: String! = "test"): Int!'

Arguments

Create arguments

Example:

// Boolean with no default value
$arg = new Argument(new BooleanType(), null, 'argName');
echo $arg; // argName: Boolean

// Boolean collection non nullable
$arg = new Argument(new BooleanType(new TypeModifier($nullable = true, $listable = true, $nullableList = false), null, 'argName');
echo $arg; // argName: [Boolean]!

// Boolean with default value
$arg = new Argument(new BooleanType(), new ValueBoolean(false), 'argName');
echo $arg; // argName: Boolean = false

Values

Set simple scalar values for default values in the schema.

Available values:

GQLSchema\Values\ValueBoolean
GQLSchema\Values\ValueFloat
GQLSchema\Values\ValueInteger
GQLSchema\Values\ValueNull
GQLSchema\Values\ValueString

Example:

$bool = new ValueBoolean(true);
$bool->getValue(); // true
echo $bool; // 'true'

$float = new ValueFloat(23.45);
$float->getValue(); // 23.45
echo $float; // '23.45'

$int = new ValueInteger(5);
$float->getValue(); // 5
echo $float; // '5'

$null = new ValueNull();
$null->getValue(); // null
echo $null; // 'null'

$string = new ValueString('test string);
$string->getValue(); // 'test string'
echo $string; // '"test string"'
