Supported +system attributes (entities and keys)

The SystemInfo +Service API supports the following system attribute entities:

Battery
Connectivity
Device
Display
Features
General
Memory
Network

The following tables describe the system attributes supported by the +SystemInfo Service API. Read the columns as follows:

Key specifies the name of the system attribute key. +Together with the entity, this specifies the system attribute; for example: Battery +- BatteryStrength.
Input specifies the system +data type for an input value. The properties specified for a particular +data type are used as the SystemData properties in method +input. NA indicates that no input is applicable.
Output specifies the system +data type for an output value. The properties specified for a particular +data type are used as the ReturnValue properties in method +output.
Value optionally describes the value or the value +range of the system attribute, or provides an example value. This is used +for both input, if valid, and output. For detailed information about system +attribute values, see section System data types.
+
GetInfo, SetInfo, and GetNotification indicate +whether the system attribute supports the GetInfo, SetInfo, +and GetNotification methods, +respectively.
GetInfo mode indicates whether the system attribute +supports synchronous (Sync) or asynchronous (Async) GetInfo calls.
+
Capability specifies the Symbian capabilities required +of any process that loads the Web Runtime to +invoke the SystemInfo Service API and access the system attribute.
+
