Node:Data Types, Previous:Abstract Objects, Up:Def Cmds in Detail
Here is the command for data types:
@deftp category name attributes...
@deftp
command is the generic definition command for data
types. The command is written at the beginning of a line and is
followed on the same line by the category, by the name of the type
(which is a word like int
or float
), and then by names of
attributes of objects of that type. Thus, you could use this command
for describing int
or float
, in which case you could use
data type
as the category. (A data type is a category of
certain objects for purposes of deciding which operations can be
performed on them.)
In Lisp, for example, pair names a particular data
type, and an object of that type has two slots called the
CAR and the CDR. Here is how you would write the first line
of a definition of pair
.
@deftp {Data type} pair car cdr ... @end deftp
The template is:
@deftp category name-of-type attributes... body-of-definition @end deftp
@deftp
creates an entry in the index of data types.
