The Haxe Reflection API allows retrieval of type information at runtime.
This class complements the more lightweight Reflect class, with a focus on class and enum instances.

Static methods
staticallEnums<T>(e:Enum<T>):Array<T>
Returns a list of all constructors of enum e
that require no
arguments.
This may return the empty Array []
if all constructors of e
require
arguments.
Otherwise an instance of e
constructed through each of its non-
argument constructors is returned, in the order of the constructor
declaration.
If e
is null, the result is unspecified.
staticcreateEmptyInstance<T>(cl:Class<T>):T
Creates an instance of class cl
.
This function guarantees that the class constructor is not called.
If cl
is null, the result is unspecified.
staticcreateEnum<T>(e:Enum<T>, constr:String, ?params:Array<Dynamic>):T
Creates an instance of enum e
by calling its constructor constr
with
arguments params
.
If e
or constr
is null, or if enum e
has no constructor named
constr
, or if the number of elements in params
does not match the
expected number of constructor arguments, or if any argument has an
invalid type, the result is unspecified.
staticcreateEnumIndex<T>(e:Enum<T>, index:Int, ?params:Array<Dynamic>):T
Creates an instance of enum e
by calling its constructor number
index
with arguments params
.
The constructor indices are preserved from Haxe syntax, so the first declared is index 0, the next index 1 etc.
If e
or constr
is null, or if enum e
has no constructor named
constr
, or if the number of elements in params
does not match the
expected number of constructor arguments, or if any argument has an
invalid type, the result is unspecified.
staticcreateInstance<T>(cl:Class<T>, args:Array<Dynamic>):T
Creates an instance of class cl
, using args
as arguments to the
class constructor.
This function guarantees that the class constructor is called.
Default values of constructors arguments are not guaranteed to be taken into account.
If cl
or args
are null, or if the number of elements in args
does
not match the expected number of constructor arguments, or if any
argument has an invalid type, or if cl
has no own constructor, the
result is unspecified.
In particular, default values of constructor arguments are not guaranteed to be taken into account.
staticenumConstructor(e:EnumValue):String
Returns the constructor name of enum instance e
.
The result String does not contain any constructor arguments.
If e
is null, the result is unspecified.
staticenumEq<T>(a:T, b:T):Bool
Recursively compares two enum instances a
and b
by value.
Unlike a == b
, this function performs a deep equality check on the
arguments of the constructors, if exists.
If a
or b
are null, the result is unspecified.
staticenumIndex(e:EnumValue):Int
Returns the index of enum instance e
.
This corresponds to the original syntactic position of e
. The index of
the first declared constructor is 0, the next one is 1 etc.
If e
is null, the result is unspecified.
staticenumParameters(e:EnumValue):Array<Dynamic>
Returns a list of the constructor arguments of enum instance e
.
If e
has no arguments, the result is [].
Otherwise the result are the values that were used as arguments to e
,
in the order of their declaration.
If e
is null, the result is unspecified.
staticgetClass<T>(o:T):Null<Class<T>>
Returns the class of o
, if o
is a class instance.
If o
is null or of a different type, null is returned.
In general, type parameter information cannot be obtained at runtime.
staticgetClassFields(c:Class<Dynamic>):Array<String>
Returns a list of static fields of class c
.
This does not include static fields of parent classes.
The order of the fields in the returned Array is unspecified.
If c
is null, the result is unspecified.
staticgetClassName(c:Class<Dynamic>):String
Returns the name of class c
, including its path.
If c
is inside a package, the package structure is returned dot-
separated, with another dot separating the class name:
pack1.pack2.(...).packN.ClassName
If c
is a sub-type of a Haxe module, that module is not part of the
package structure.
If c
has no package, the class name is returned.
If c
is null, the result is unspecified.
The class name does not include any type parameters.
staticgetEnum(o:EnumValue):Enum<Dynamic>
Returns the enum of enum instance o
.
An enum instance is the result of using an enum constructor. Given an
enum Color { Red; }
, getEnum(Red)
returns Enum<Color>
.
If o
is null, null is returned.
In general, type parameter information cannot be obtained at runtime.
staticgetEnumConstructs(e:Enum<Dynamic>):Array<String>
Returns a list of the names of all constructors of enum e
.
The order of the constructor names in the returned Array is preserved from the original syntax.
If e
is null, the result is unspecified.
staticgetEnumName(e:Enum<Dynamic>):String
Returns the name of enum e
, including its path.
If e
is inside a package, the package structure is returned dot-
separated, with another dot separating the enum name:
pack1.pack2.(...).packN.EnumName
If e
is a sub-type of a Haxe module, that module is not part of the
package structure.
If e
has no package, the enum name is returned.
If e
is null, the result is unspecified.
The enum name does not include any type parameters.
staticgetInstanceFields(c:Class<Dynamic>):Array<String>
Returns a list of the instance fields of class c
, including
inherited fields.
This only includes fields which are known at compile-time. In
particular, using getInstanceFields(getClass(obj))
will not include
any fields which were added to obj
at runtime.
The order of the fields in the returned Array is unspecified.
If c
is null, the result is unspecified.
staticgetSuperClass(c:Class<Dynamic>):Class<Dynamic>
Returns the super-class of class c
.
If c
has no super class, null is returned.
If c
is null, the result is unspecified.
In general, type parameter information cannot be obtained at runtime.
staticresolveClass(name:String):Class<Dynamic>
Resolves a class by name.
If name
is the path of an existing class, that class is returned.
Otherwise null is returned.
If name
is null or the path to a different type, the result is
unspecified.
The class name must not include any type parameters.
staticresolveEnum(name:String):Enum<Dynamic>
Resolves an enum by name.
If name
is the path of an existing enum, that enum is returned.
Otherwise null is returned.
If name
is null the result is unspecified.
If name
is the path to a different type, null is returned.
The enum name must not include any type parameters.
