Enum Methods
An enum is an abstract data type with values that each
take on exactly one of a finite set of identifiers that you specify. Apex provides built-in enums, such as LoggingLevel, and you can define your own enum.
All Apex enums, whether user-defined enums or built-in enums, have the following common method that takes no arguments.
- values
- This method returns the values of the Enum as a list of the same Enum type.
Each Enum value has the following methods that take no arguments.
- name
- Returns the name of the Enum item as a String.
- ordinal
- Returns the position of the item, as an Integer, in the list of Enum values starting with zero.
Enum values cannot have user-defined methods added to them.
For more information about Enum, see Enums.
Example
1Integer i = StatusCode.DELETE_FAILED.ordinal();
