argo/types
==========

[](#argotypes)

Extended PHP type definition system.

Allows for more complete description of types in PHP, taking into account not only built-in types but also extended phpstan/psalm types, described in PHPDoc. This package itself only provides classes with type descriptions.

### Argo\\Types\\TypeInterface

[](#argotypestypeinterface)

A common interface for all types. Provides several common methods:

```
public function isNullable(): bool;
```

Checks that the specified type is nullable (that is, it allows null to be used as a value).

```
public function setNullable(): TypeInterface;
```

Returns a new instance of the type that is nullable. If the type was already nullable, it returns itself.

```
public function __toString(): string;
```

Returns a string representation of the type. This returns a full description of the type, suitable for PHPDoc.

```
public function toNativeTypeString(): string;
```

Returns a string representation of a native PHP type.

```
public function isContravariantTo(TypeInterface $type): bool;
```

Checks whether the given type is contravariant with respect to the passed `$type`.

### Argo\\Types\\NamedTypeInterface

[](#argotypesnamedtypeinterface)

An interface implemented by all non-generic or complex types. It provides no additional methods.

### Argo\\Types\\Atomic\*

[](#argotypesatomic)

This namespace contains basic PHP types:

- `ArrayType` - array type
- `BoolType` - bool type
- `Callable` - callable type
- `ClassType` - type for all non-anonymous classes
- `FloatType` - float type
- `IntType` - int type
- `MixedType` - mixed type
- `NeverType` - never type
- `NotType` - a special type for aliases that represents the negation of the type
- `NullType` - null type
- `ObjectType` - object type
- `ResourceType` - resource type
- `StringType` - string type
- `VoidType` - void type

### Argo\\Types\\Alias\*

[](#argotypesalias)

Special aliases for types:

- `ArrayKeyType` - array-key (int|string)
- `CallableStringType` - callable-string (string)
- `ClassStringType` - class-string (string)
- `FalseType` - false (bool)
- `FloatConstType` - constant float (e.g. 1.23)
- `IntConstType` - constant int (e.g. 123)
- `IntMaskOfType` - int-mask-of (int)
- `IntMaskType` - int-mask (int)
- `IntRangeType` - int<min,max> (int)
- `IterableType` - iterable (array|\\Traversable)
- `ListType` - list (array)
- `NegativeIntType` - negative-int (int)
- `NonEmptyArrayType` - non-empty-array (array)
- `NonEmptyListType` - non-empty-list (array)
- `NonEmptyStringType` - non-empty-string (string)
- `NonFalsyStringType` - non-falsy-string (string)
- `NonNegativeIntType` - non-negative-int (int)
- `NonPositiveIntType` - non-positive-int (int)
- `NumericStringType` - numeric-string (string)
- `NumericType` - numeric (int|float|numeric-string)
- `PositiveIntType` - positive-int (int)
- `ScalarType` - scalar (string|int|float|bool)
- `StringConstType` - constant string (e.g. "hello")
- `TraitStringType` - trait-string (string)
- `TrueType` - true (bool)
- `TruthyStringType` - truthy-string (string)

### Argo\\Types\\Complex\*

[](#argotypescomplex)

Complex types:

- `IntersectType` - intersection type of several types (intersect)
- `UnionType` - union type of several types (union)
