MemoryMonitor Class Reference
[QtBaseModule, QtDevToolsModule]

Detailed Description

The MemoryMonitor class interface determines the available amount of available memory.

The MemoryMonitor class provides an abstract interface for querying and monitoring the amount of system memory available. As a task interface, it is never instantiated directly. It is instantiated by a qtopiaTask<MemoryMonitor>() call.

The MemoryMonitor interface is an optional task interface, so consumers must be prepared for a request for this interface to fail.

This class is part of the Qt Extended server and cannot be used by other Qt Extended applications.

Member Type Documentation

enum MemoryMonitor::MemState

The MemState enumeration represents the memory level in the system.

Member Function Documentation

MemState MemoryMonitor::memoryState () const   [pure virtual]

The subclass must implement this function. It must return the current memory state. The four memory states are Critical, Very Low, Low, and Normal.

void MemoryMonitor::memoryStateChanged ( MemoryMonitor::MemState newState )   [signal]

This signal is emitted whenever the memory state changes. newState will be set to the new memory state.

unsigned int MemoryMonitor::timeInState () const   [pure virtual]

The subclass must implement this function. It must return the time, in seconds, since the last memory state change.
