A:

Controls all aspects of building a project in the SBSv1 build system. It is created in the current directory by the bldmake tool from a component description file.

See also: bldmake tool 

Used to describe a class which describes behaviour, but which does not implement it. Many implementations of the behaviour might be available. Each is referred to as a concrete class.

A record of the number of objects referencing a contact item. A contact item cannot be fully deleted until its access count is zero.

See also: contact item  

The locking specified when opening a file: exclusive, readers only, or shared with any.

A class derived from CActive, which is responsible for issuing requests to asynchronous service providers and handling those requests on completion.

See also: active scheduler  asynchronous service provider  

A class derived from CActiveScheduler, responsible for scheduling events to the active objects in an event-handling program.

See also: asynchronous service provider  active object  

For Bluetooth, each Bluetooth device has built into its hardware a 48-bit device unique address.

In the context of the Network Interface Manager (NifMan), the component which NifMan uses to set up a connection. Or, in the context of a vCard, a property within a vCard whose value is a string representing another entity.

The time that the alarm was/is due. Before an alarm activates, this is the same as the alarm time. If the alarm is snoozed, then the due time remains the same, but the alarm time becomes the new activation time.

See also: alarm time  

The message which is displayed to the user when the alarm time is reached.

See also: alarm time  

An algorithmic sound or a sampled sound file stored in the system alarms directory (\System\Alarms).

See also: algorithmic sound  sampled sound file  

The time the alarm is next expected to activate.

See also: alarm due time  

A standard for encoding 12-bit sound as 8-bit data.

See also: sampled sound file  

Legacy help authoring tool.

A sound generated by the sound driver by synthesising sounds according to an algorithm.

See also: sampled sound file  

The term used where a value (called 'Alpha') is used to indicate a transparency value for a pixel. If the Alpha=maximum then the pixel is opaque, that is the full colour of the pixel is written to the destination. If Alpha=0 then the pixel is fully transparent, and the destination is left unaltered. Values in-between cause 'blending' with the formula Destination = Source*Alpha/max_Alpha + Destination*(max_Alpha-Alpha)/max_Alpha

Marks the start of a selection

Application Programming Interface, the visible public behaviour a system object or component exposes to other objects or components.

A control environment class which defines application-wide aspects of the user interface, such as key event handling. Each application that uses the control environment has exactly one app UI. or The interface an application presents to the user, or the subclass of CEikAppUi an application uses.

See also: user interface  

A program that provides a graphical user interface to the user; applications are created using the application framework which provides standard means for applications to receive input events and manage data (documents).

See also: document  

Set of properties for an application that are understood by the application architecture, such as its support for embeddability, and whether it is hidden. They are set in the application registration file provided with the application.This concept should not be confused with a program's security capabilities.

Application Binary Interface. This is a standard for the interfaces of binary code running in ARM environments, and is intended to allow inter-operation of binaries produced by different compilers that conform to the standard. The specification is published by ARM.

See also: ARM processors 

A program made up of a number of classes. It usually consists of a user interface and an application engine.

A resource file written by an application programmer as part of the application source; such files are used to define the application user interface, and to define literal strings and other constant data.

See also: resource file  

A window managed by an application, which typically displays user data.

A file attribute indicating whether it has been saved since changes were made to it. The archive attribute is assigned to a file when it is created, replaced or written to.

See also: attribute  

A processor with 16/32 bit embedded RISC from ARM.

An area containing the elements, or pointers to the elements of an array.

The number of elements which an array can hold or represent within the space currently allocated to its array buffer.

See also: array buffer  

The number of elements by which the array capacity of an array is increased.

See also: array capacity  

The ascent of a character cell defines the position of the baseline within every character cell of a font. It is the number of pixels from the top of the cell to the baseline. The baseline is not a pixel row itself, but occurs between two pixel rows.

The central user interface class. It creates and owns controls to display the application data, and centralises handling of command input from standard controls such as menus and toolbars.

Defines the properties of the application, such as UID and caption, and creates a new document.

See also: document class 

Handles application start-up and accessing the application data (its document).

The frameworks that define the application structure and their basic user interface handling.

The window associated with a control. If the control is a window-owning control, this is the window is owns. If the control is non-window-owning, it is the window in which the control is displayed, i.e., the window owned by the nearest window-owning-control above it in the run-time control hierarchy.

A value on which a function operates.

Application Specific Integrated Circuit

Application-Specific Standard Product. An integrated off-the-shelf part consisting of CPU, MMU, cache and a number of on-chip peripherals (typically UART's, timers, LCD controller). Designed and marketed by a silicon vendor and intended to be used in a class of devices.

A request for an asynchronous service from an asynchronous service provider.

See also: asynchronous service provider  

A system, component or class which provides a service asynchronously Requests are indicated by function calls with a TRequestStatus reference parameter.

See also: Request status  active object  active scheduler  asynchronous request  

Class 2 modem receive command.

A characteristic of a file or directory. Attributes determine the visibility of files and directories and whether or not they can be deleted or modified. Attributes include hidden, read-only and archive. For Bluetooth, a Bluetooth service is described by a service record, consisting of a list of service attributes. Each attribute has an ID, a type, and a value.

Playing audio data incrementally, as the data fragments are received by the client, rather than waiting until the entire sound clip has downloaded before playing it.

A transaction which is operated automatically by a database, if no explicit transaction is begun when modifying the database.
