Notational Conventions
The following conventions may be used in this document.
Convention |
Explanation |
Example |
|---|---|---|
Italic |
Used for introducing new terms, denotation of terms, placeholders, or titles of manuals. |
The filename consists of the basename and the extension. |
Monospace |
Indicates directory paths and filenames, commands and command line options, function names, methods, classes, data structures in body text, source code. |
ippsapi.h\alt\include Use the okCreateObjs() function to… printf("hello, world\n"); |
[ ] |
Items enclosed in brackets are optional. |
Fa[c] Indicates Fa or Fac. |
{ | } |
Braces and vertical bars indicate the choice of one item from a selection of two or more items. |
X{K | W | P} Indicates XK, XW, or XP. |
“[” “]” “{” | ” }” “|” |
Writing a metacharacter in quotation marks negates the syntactical meaning stated above; | the character is taken as a literal. |
“[” X “]” [ Y ] Denotes the letter X enclosed in brackets, optionally followed by the letter Y. |
… |
The ellipsis indicates that the previous item can be repeated several times. |
filename … Indicates that one or more filenames can be specified. |
,… |
The ellipsis preceded by a comma indicates that the previous item can be repeated several times, | separated by commas. |
word ,… Indicates that one or more words can be specified. If more than one word is specified, the words are comma-separated. |
Class members are summarized by informal class declarations that describe the class as it seems to clients, not how it is actually implemented. For example, here is an informal declaration of class Foo:
class Foo {
public:
int x();
int y;
~Foo();
};
The actual implementation might look like:
namespace internal {
class FooBase {
protected:
int x();
};
class Foo_v3: protected FooBase {
private:
int internal_stuff;
public:
using FooBase::x;
int y;
};
}
typedef internal::Foo_v3 Foo;
The example shows two cases where the actual implementation departs from the informal declaration:
Foo is actually a typedef to Foo_v3.
Method x() is inherited from a protected base class.
The destructor is an implicit method generated by the compiler.
The informal declarations are intended to show you what you need to know to use the class without the distraction of irrelevant clutter particular to the implementation.
