Reflect
Reflect
Available on all platformsThe Reflect API is a way to manipulate values dynamically through an abstract interface in an untyped manner. Use with care.
See:
Static methods
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.
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-
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.
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-
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.
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.
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.
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.
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-
static isFunction (f:Dynamic):Bool
Returns true if f is a function, false otherwise-
If f is null, the result is false-
static isObject (v:Dynamic):Bool
Tells if v is an object-
The result is true if v is one of the following:
Otherwise, including if v is null, the result is false-
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-
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-
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.
