E
exception An exception is a runtime error condition. Exception handling is a C++ mechanism that allows
the error detector to pass the error condition to the exception handler. An exception is raised by
a throw statement within a try block and handled by a catch clause. The ANSI/ISO C++
International Standard defines only synchronous exceptions.
explicit
instantiation
A method of instantiation that instantiates a template at the point of its use. You can code an
explicit template instantiation, as defined in the Final Draft International Standard, in your source
file.
external symbol A name of a function or data item in an object file that you can link with other object files.
F
friend A class or a function that has access to data of a class and member functions. Friend has access
to the public, protected, and private members of a class.
function template A template that defines an unbounded set of related functions.
H
header file A C++ source file typically containing class or function declarations. It is referenced by other
C++ source files using the #include preprocessor directive.
HP aC++ The latest C++ compiler from HP. It closely complies with most features of the ANSI/ISO C++
International Standard.
HP C++ An initial, pre-C++ draft proposed international standard C++ compiler from HP. It is based on
the cfront compiler and provides functionality for templates and exception handling.
I
include guards Preprocessor commands, such as, #ifndef, #define, and #endif, used in a header file to
prevent compiling that file more than once.
inline function A function whose code is copied in place of each function call.
instantiate To form an instantiation by binding a template to particular argument types.
instantiated class A class generated from a class template by instantiation.
instantiated
function
A function generated from a function template by instantiation.
instantiation A generated class or function (a definition) that is the result of binding a template to particular
argument types. Also known as a generation.
L
lex A program generator for lexical analysis of text.
link unit A single entity submitted to the linker. A link unit can be an object file (.o file, the output of a
translation unit), an archive library (.a file), or a shared library (.so file).
load compile Invoking the compiler using the +hdr_use option, and a manual precompiled header file.
M
member data Any data element declared to be part of a class.
member function Any function declared to be part of a class.
multiple
inheritance
The ability of a class to inherit from more than one base class. The derived class inherits all public
and protected members from all of its base classes. Also see single inheritence.
N
name demangling The process of changing the internal representation of identifiers back to their original C++ source
names. Also see name mangling.
