objects. Recycling allows for objects that have become unusable to be destroyed
and replaced with fresh server objects and to reclaim resources taken up by stale
server objects.
A pointer to an object, interface, or other item allocated in memory. COM objects
keep a running total of the references to themselves via the IUnknown interface
methods AddRef and Release.
A utility, part of the Windows operating system, that allows you to view and edit
the system registry.
To add information about a component to the system registry, generally performed
using RegSvr32.
Stores information about system configuration for a Windows machine. COM
uses the registry extensively, storing details of COM components including
ProgIDs and ClassIDs, file location of the binary code, marshalling information,
and categories in which they participate.
A file containing information in Windows Registry format. Double-clicking a .reg
file in Windows will enter the information in the file to the system registry. Often
used to register components to component categories.
A Windows utility that can add information about a component to the system
registry. A component must be registered before it can be used.
To reinstantiate an object and its state from persisted storage.
To draw to a display. The conversion of the geometry, coloring, texturing, lighting,
and other characteristics of an object into a display image.
The host that provides the services required for compiled code to execute. The
Service Control Manager is effectively the runtime environment for COM. The
Visual Basic Virtual Machine (VBVM) is the runtime environment that runs
Visual Basic code.
A system that does not show negative effects when its size or complexity grows
greater.
Service Control Manager. An administrative tool that enables the creation and
modification of system services. It effectively serves as the runtime environment
for COM.
A set of instructions in plain text, usually stored in a file and interpreted, or
compiled, at runtime. In geoprocessing, scripts can be used to automate tasks,
such as data conversion, or generate geodatabases and can be run from their
scripting application or added to a toolbox. Geoprocessing scripts can be written
in any COM-compliant scripting language, such as Python, JScript, or VBScript.
A form of persistence, in which an object is written out in sequence to a target,
usually a stream. See also persistence.
1. A computer in a network that is used to provide services, such as access to files
or e-mail routing, to other computers in the network. Servers may also be used to
host Web sites or applications that can be accessed remotely. 2. An item that
provides functionality to a client—for example, a COM component or object to a
user application using components or to a database client utility using a database
on a server machine.
