Request

Add an Enum.GetName() method for the Enum datatype.

Similar to how we have an Enum.AsInteger() method.

Syntax

The Name of the Enum Value as a Text value := Enum.GetName()

Parameters

Enum

Type: Enum

An instance of the Enum data type.

Return Value

The Name of the Enum Value as a Text value

Type: Text

Examples

  local procedure Sample1(CustomerStatus: Enum "Customer Status")

  var

    EnumValueName: Text;

  begin

    EnumValueName := CustomerStatus.GetName();

  end;

  local procedure Sample2()

  var

    EnumValueName: Text;

  begin

    EnumValueName := Enum::"Customer Status"::"Gold Customer".GetName();

  end;

Explanation and Motivation

I am aware that we can currently use the following code to get the Enum value name, but it is very inefficient:

(See GitHub issue 5576: https://github.com/microsoft/AL/issues/5576#issuecomment-572456605)

  procedure GetEnumValueName(MyTestEnum: Enum TestEnum) Name: Text;

  var

    Index: Integer;

  begin

    Index:= MyTestEnum.Ordinals.IndexOf(MyTestEnum.AsInteger());

    MyTestEnum.Names.Get(Index, Name);

  end;

Instead I would like to get an instantaneous result, rather than needing an O(n) IndexOf-operation to get the enum name (impacting performance) and requiring multiple statements to achieve this.

So translating that example in what we would like to see:

  procedure GetEnumValueName(MyTestEnum: Enum TestEnum) Name: Text;

  var

    Index: Integer;

  begin

    Name := MyTestEnum.GetName();

  end;
