Erlang中的Record详解. 更新时间：2015年04月29日 10:21:54 投稿：junjie. 这篇文章主要介绍了Erlang中的Record详解,本文讲解了定义Record、创建Record、访问Record、更新Record、匹配Record和Guard语句、使用Record等内容,需要的朋友可以参考下. 在Erlang内部只有两种混合的数据类型：List和Tuple，而这两种都不支持命名访问，所以如果没有额外的库的话想创建像PHP、Ruby或Python中的关联数组（Ruby中 Erlang is mostly a functional language, Thus, for representing a C-like struct, Erlang provides a record type that you can use to specify a little abstraction over plain tuples. For years, people have been complaining about records and key/value data structures on multiple fronts in the Erlang community: People don't want to put the name of the record every time when accessing it and want dynamic access There is no good canonical arbitrary key/value store to target and use in pattern matches It looks like we're updating the record in place (Rob#robot{Field=NewValue}) but it's all compiler trickery to call the underlying erlang:setelement/3 function.

Erlang record

Since Erlang is side-effect free state cannot be kept globally. Instead it must be passed around from function to function. 2 Public key records.

.hrl files can contain any valid Erlang code but are most often used for record and macro definitions. 5.3 Records A record is defined as: -record(name_of_record, {field_name1, field_name2, field_name3,}).

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}.

同时一些常量如果硬编码到代码中,一旦数值变化,要想全部可靠的替换成新的数值是一个困难的事情. 2007-12-16 · Instead, there’s a pre-processor in Erlang, and records are defined by translation in the pre-processor. This to me typifies one of the less attractive attributes of Erlang: much of Erlang has a very ad-hoc flavor to it. There are important high-level features – like record data and modules – which aren’t really entirely part of the Hi, Currently I'm building an application that needs to do a lot of record checking by counting the number of records in a mnesia table based on some condition.

5.3 Records A record is defined as: -record(name_of_record, {field_name1, field_name2, field_name3,}). Records are not a special type in erlang, but a simple tuple which first term is the name of the tuple. Everything is solved at compilation, so it does not make sense to test the existence of a field at run time since it should not pass the compilation: I don't know any way to access a record field without explicitly using the field name. When writing Erlang programs, it is also allowed to use macro- and record expressions. However, these expressions are expanded during compilation and are in that sense not true Erlang expressions. Macro- and record expressions are covered in separate sections: Preprocessor. Records.
