Any | `Any` is a type that is compatible with any other in both ways.
Array | An Array is a storage for values. You can access it using indexes or with its API.
ArrayAccess | `ArrayAccess` is used to indicate a class that can be accessed using brackets. The type parameter represents the type of the elements stored.
Bool | The standard Boolean type, which can either be `true` or `false`.
Class | An abstract type that represents a Class.
Date | The Date class provides a basic structure for date and time related information. Date instances can be created by
Dynamic | `Dynamic` is a special type which is compatible with all other types.
EReg | The EReg class represents regular expressions.
Enum | An abstract type that represents an Enum type.
EnumValue | An abstract type that represents any enum value. See `Type` for the Haxe Reflection API.
Float | The standard `Float` type, this is a double-precision IEEE 64bit float.
Int | The standard `Int` type. Its precision depends on the platform.
Iterable | An `Iterable` is a data structure which has an `iterator()` method. See `Lambda` for generic functions on iterable structures.
Iterator | An `Iterator` is a structure that permits iteration over elements of type `T`.
List | A linked-list of elements. The list is composed of element container objects that are chained together. It is optimized so that adding or removing an element does not imply copying the whole list content every time.
Map | Map allows key to value mapping for arbitrary value types, and many key types.
Math | This class defines mathematical functions and constants.
Null | `Null` can be useful in two cases. In order to document some methods that accept or can return a `null` value, or for the Flash compiler and AS3 generator to distinguish between base values that can be `null` and others that can't.
Reflect | The Reflect API is a way to manipulate values dynamically through an abstract interface in an untyped manner. Use with care.
Std | The Std class provides standard methods for manipulating basic types.
String | The basic String class.
StringBuf | A String buffer is an efficient way to build a big string by appending small elements together.
StringTools | This class provides advanced methods on Strings. It is ideally used with `using StringTools` and then acts as an extension to the `String` class.
Sys | This class gives you access to many base functionalities of system platforms. Looks in `sys` sub packages for more system APIs.
Type | The Haxe Reflection API allows retrieval of type information at runtime.
UInt | The unsigned `Int` type is only defined for Flash and C#. Simulate it for other platforms.
ValueType |
Void | The standard `Void` type. Only `null` values can be of the type `Void`.
Xml | Cross-platform Xml API.
XmlType | Xml node types.
