Detailed Description

Implementation of ProcessInfo which does nothing.

Used on platforms where a suitable ProcessInfo subclass is not available.

isValid() will always return false for instances of NullProcessInfo

Definition at line 327 of file ProcessInfo.h.

Constructor & Destructor Documentation

◆ NullProcessInfo()

NullProcessInfo::NullProcessInfo ( int pid,
bool readEnvironment = false )
explicit

Constructs a new NullProcessInfo instance.

See ProcessInfo::newInstance()

Definition at line 339 of file ProcessInfo.cpp.

Member Function Documentation

◆ readProcessInfo()

bool NullProcessInfo::readProcessInfo ( int pid,
bool readEnvironment )
overrideprotectedvirtual

This is called on construction to read the process state Subclasses should reimplement this function to provide platform-specific process state reading functionality.

When called, readProcessInfo() should attempt to read all of the necessary state information. If the attempt is successful, it should set the process id using setPid(), and update the other relevant information using setParentPid(), setName(), setArguments() etc.

Calls to isValid() will return true only if the process id has been set using setPid()

Parameters
pidThe process id of the process to read
readEnvironmentSpecifies whether the environment bindings for the process should be read

Implements Konsole::ProcessInfo.

Definition at line 344 of file ProcessInfo.cpp.

◆ readUserName()

void NullProcessInfo::readUserName ( void )
overrideprotectedvirtual

Implements Konsole::ProcessInfo.

Definition at line 349 of file ProcessInfo.cpp.
