The Reflect API is a way to manipulate values dynamically through an abstract interface in an untyped manner. Use with care.

Static methods

@:has_untyped static callMethod (o:Dynamic, func:Function, args:Array<Dynamic>):Dynamic

Call a method with the given object and arguments.

static compare<T> (a:T, b:T ):Int

Compares a and b.

If a is less than b, the result is negative. If b is less than a, the result is positive. If a and b are equal, the result is 0.

This function is only defined if a and b are of the same type.

If that type is a function, the result is unspecified and Reflect.compareMethods should be used instead.

For all other types, the result is 0 if a and b are equal. If they are not equal, the result depends on the type and is negative if:

• Numeric types: a is less than b
• String: a is lexicographically less than b
• Other: unspecified

If a and b are null, the result is 0. If only one of them is null, the result is unspecified.

@:has_untyped static compareMethods (f1:Dynamic, f2:Dynamic):Bool

Compares the functions f1 and f2.

If f1 or f2 are not functions, the result is unspecified.

Otherwise the result is true if f1 and the f2 are physically equal, false otherwise.

@:has_untyped static copy<T> (o:T ):T

Copies the fields of structure o.

This is only guaranteed to work on anonymous structures.

If o is null, the result is unspecified.

@:has_untyped static deleteField (o:Dynamic, field:String):Bool

Removes the field named field from structure o.

This method is only guaranteed to work on anonymous structures.

If o or field are null, the result is unspecified.

@:has_untyped static field (o:Dynamic, field:String):Dynamic

Returns the value of the field named field on object o.

If o is not an object or has no field named field, the result is null.

If the field is defined as a property, its accessors are ignored. Refer to Reflect.getProperty for a function supporting property accessors.

If field is null, the result is unspecified.

(As3) If used on a property field, the getter will be invoked. It is not possible to obtain the value directly.

@:has_untyped static fields (o:Dynamic):Array<String>

Returns the fields of structure o.

This method is only guaranteed to work on anonymous structures. Refer to Type.getInstanceFields for a function supporting class instances.

If o is null, the result is unspecified.

@:has_untyped static getProperty (o:Dynamic, field:String):Dynamic

Returns the value of the field named field on object o, taking property getter functions into account.

If the field is not a property, this function behaves like Reflect.field, but might be slower.

If o or field are null, the result is unspecified.

@:has_untyped static hasField (o:Dynamic, field:String):Bool

Tells if structure o has a field named field.

This is only guaranteed to work for anonymous structures. Refer to Type.getInstanceFields for a function supporting class instances.

If o or field are null, the result is unspecified.

@:has_untyped static isEnumValue (v:Dynamic):Bool

Tells if v is an enum value.

The result is true if v is of type EnumValue, i.e. an enum constructor.

Otherwise, including if v is null, the result is false.

@:has_untyped static isFunction (f:Dynamic):Bool

Returns true if f is a function, false otherwise.

If f is null, the result is false.

@:has_untyped static isObject (v:Dynamic):Bool

Tells if v is an object.

The result is true if v is one of the following:

• class instance
• structure
• Class<T>
• Enum<T>

Otherwise, including if v is null, the result is false.

@:has_untyped static makeVarArgs (f:Array<Dynamic> ‑> Dynamic):Dynamic

static makeVarArgs (f:Array<Dynamic> ‑> Void):Dynamic

Transform a function taking an array of arguments into a function that can be called with any number of arguments.

@:has_untyped static setField (o:Dynamic, field:String, value:Dynamic):Void

Sets the field named field of object o to value value.

If o has no field named field, this function is only guaranteed to work for anonymous structures.

If o or field are null, the result is unspecified.

(As3) If used on a property field, the setter will be invoked. It is not possible to set the value directly.

@:has_untyped static setProperty (o:Dynamic, field:String, value:Dynamic):Void

Sets the field named field of object o to value value, taking property setter functions into account.

If the field is not a property, this function behaves like Reflect.setField, but might be slower.

If field is null, the result is unspecified.
