E
E32
Original name for the base components of Symbian OS.
ECOM
Symbian OS framework for plug-in DLLs which allows sending and receiving of SMS messages.
ear
A triangular button that can be pressed to set another control to the next or previous in sequence. Ears are displayed to either side of the control they affect.
editable text
Text and other text object components (including pictures and other attachments) that may be edited under program control. An interface is provided to the layout engine so that editable text can be displayed on screen, and commands and selections made from the screen. The two most important forms of editable text are rich text and global text.
EFF
Electronic Font Foundry.
effective format
The set of format attributes that apply to a character or paragraph. Consists of the attributes specified by the applicable format layers.
EGL
OpenGL ES native platform graphics interface
EIKON framework
A GUI programming framework including concrete controls and standard dialogs, which was replaced in v5.1 by UIKON and device-specific UI libraries.
Electronic Font Foundry format
Font format licensed by Symbian for use in Symbian OS. Also referred to as EFF.
embeddable capability
Embeddable documents can be embedded within another application.
empty
A rectangle is empty when the area contained within it is zero or negative. This situation occurs when the rectangle is not normalised, or when it has a height or width of zero. A region is empty if it contains no rectangles.
Emulator
An implementation of Symbian OS hosted on PCs running Microsoft Windows. The Emulator is the primary development environment for Symbian OS.
End entity certificate
A certificate which has been signed by a certification authority. An EE certificate may be used to sign a SIS file or a MIDlet, but may not be used to sign certificates.
engine
The UI and view independent portion of an application, concerned with data manipulation and other fundamental operations independently of how these are eventually represented to the user.
Engine Utilities
Also known as BAFL, this component provides utilities for applications.
entity
An object to be parsed by the Versit parser. The entity types supported by Versit are: vCalendar, vCard, vEvent, vTodo. Entities may either be top level entities, or sub-entities.
entry
A directory entry. This may be either a file or directory. or An item recorded in the Index by the Message Server, such as a message, service, folder, or attachment. Each Index entry (and so each item) is uniquely identified by an ID field.
entry ID
Uniquely identifies an agenda entry in an agenda file. Unlike the unique ID, the entry ID can change if the entry is updated, or if another entry is deleted from or added to the file. It therefore cannot be used to identify the entry during synchronisation.
entry observer
A class implemented by a messaging client that is notified when the data representing an individual entry changes, or when requested access to a message store has been successfully gained.
entry point
In Symbian OS before v9, a function E32Dll() that was called when a DLL was loaded, or attached by a thread or process.
entry symbol
The character which is used to represent an entry in Agenda application views.
EOP
End Of Procedure. Indicates the end of a complete page of fax information, and that no further documents are expected. Proceed to phase E upon receipt of a confirmation.
EPOC
The original name for Symbian OS.
ESOCK
The Symbian OS sockets framework. It provides an abstract sockets interface, for which extensions to support particular sockets protocols, such as TCP/IP, can be written.
ETel
The Symbian OS telephony framework. It provides an abstract telephony interface, for which extensions to support particular telephony protocols or devices can be written.
ETel core API
The ETel API that implements the subset of near-universally supported telephony functionality.
ETEXT
The Symbian OS component that relates to text content and formatting.
event
A loose term used to describe the cause of the completion of a request to an event source.
event queue
A queue of keyboard, pointer and redraw events maintained by the window server, for each of its current client applications.
event source
An asynchronous service provider that causes requests to complete when some event (usually not directly solicited) occurs. Event sources must buffer the events they detect, until they are able to "give" them to a user program by virtual of a request completion. Buffer overrun is a real possibility.
exception
Abnormal condition that causes the CPU to stop what it is doing and jump to a specific piece of code.Or In an agenda entry's repeat details, a date for which the repeat algorithm does not apply.
excess width
The width over which excess space is to be distributed when drawing justified text.
exe
An Executable file that contains the code for a program.
exec call
A call to the Kernel via a software interrupt.
export
Within the context of a DLL, to make a function or data available for use by application programs or other DLLs.
export by ordinal
Within the context of a DLL, an exported function referred to by its ordinal number instead of by name.
expose
A window is completely or partly exposed when a window that used to be on top of it is moved or destroyed.
extension
Identifies the type of a file. It comprises everything after the final dot. If there is no final dot, the extension is empty.
extent
A control or window's position and size.
externalise
The process of writing an object's data to a stream.
