For AMF implementation, I have to define the mapping between Actionscript classes with something equivalent in Erlang.First thing came into my mind is record.However, I immediately encountered some of the difficulties when using records in Erlang
To illustrate these differences, suppose that you want to represent a person with the tuple {Name, Address, Phone}. A record is a data structure for storing a fixed number of elements. It has named fields and is similar to a struct in C. Record expressions are translated to tuple expressions during compilation. Therefore, record expressions are not understood by the shell unless special actions are taken. See shell (3) for details. There are various ways to do this.
Regardless of Erlang jobs. 307 open jobs. Add erlang-ejournald, erlang-lager_journald_backend, and make Journald as a default logging backend. Solid track record of delivering successful projects. 6 Erlang -record(person, {name, age).
5. Erlang record syntax with single quotes.
1 Records 1.1 Records and Tuples. The main advantage of using records rather than tuples is that fields in a record are accessed by name, whereas fields in a tuple are accessed by position. To illustrate these differences, suppose that you want to represent a person with the tuple {Name, Address, Phone}.

This file defines the record definitions for various Erlang record types that are useful for representing DNS constructs. For example, the dns_message record represents all of the elements that you would find in a single DNS message.
For example, you can define a personal record which has 2 fields, one is the id and the other is the name field. In Erlang, you can then create various instances of this record to define multiple people with various names and id’s. 1 Records 1.1 Records and Tuples. The main advantage of using records rather than tuples is that fields in a record are accessed by name, whereas fields in a tuple are accessed by position.
