                   RADService _composition,
                   UsernamePasswordPrincipal _principal,

                   byte[] _hostkey)

TODO: Javadoc

Parameters:

_management -

_dependency -

_composition -

_principal -

_hostport -

_hostkey -

Method Detail

boottime

@StaticGetMethod(value="System.BootTime")
public Date boottime()

TODO: Javadoc

Returns:

cachedSession

private LinuxSession cachedSession(RADService _composition)

TODO: Javadoc

Returns:

connect

public LinuxSession connect(UsernamePasswordPrincipal _principal)

Description copied from interface: SecureSystem

TODO: Javadoc

Specified by:

connect in interface SecureSystem<UsernamePasswordPrincipal>

Specified by:

connect in interface NetworkSystem<UsernamePasswordPrincipal>

Parameters:

_principal - Can be null to use the default principal

Returns:

connect

public LinuxSession connect(UsernamePasswordPrincipal _principal,
                            RADService _composition)

TODO: Javadoc

Parameters:

_principal -

_composition -

Returns:

disconnect

public void disconnect()

Description copied from interface: SecureSystem

TODO: Javadoc

Specified by:

disconnect in interface SecureSystem<UsernamePasswordPrincipal>

getArchive

@StaticOperation(value="System.GetArchive")
public File getArchive(@StaticParameter(value="path",use=Option)
                                            String path)

TODO: Javadoc

Parameters:

path -

Returns:

isConcrete

public boolean isConcrete()

Description copied from interface: RADService

Determine if this RADService is a concrete service, or simply an arbitrary abstraction built for management purposes.

Specified by:

isConcrete in interface RADService

Returns:

true if this object represents a concrete service. false if this object represents an arbitrary abstraction, and does not correspond to a real service.

loadNagiosProperties

private void loadNagiosProperties(LinuxSession session)

TODO: Javadoc

ping

@StaticOperation(value="System.Ping")
public boolean ping(HostPort _hostport)

TODO: Javadoc

Parameters:

_hostport -

Returns:

principal

public UsernamePasswordPrincipal principal()

Description copied from interface: SecureSystem

TODO: Javadoc

Specified by:

principal in interface SecureSystem<UsernamePasswordPrincipal>

Returns:

The default security principal.

radServiceState

public DynamicProperty<RADService.State> radServiceState()

Description copied from interface: RADService

Returns the dynamic property object for the state of this service. The dynamic property can then be used to query the actual state, or to set it. There are few restrictions on state, except that it must be RADService.State.Unknown when RADService.management().parent().get().radServiceState().get() != RADService.State.Running.

Note that the ImmutableSingletonInterface.get() and SingletonInterface#set() methods on the dynamic property refer to the offline state of this service. The RADService.refresh() and RADService.update(boolean, RADService.State) methods can be used to synchronize this state with the state of the actual service. SingletonInterface#set() will schedule a call to RADService.update(boolean, RADService.State) so that the service state will be updated in the future.

Specified by:

radServiceState in interface RADService

Returns:

The dynamic property which represents the offline state of this service.

setArchive

public void setArchive(@StaticParameter(value="path",use=Option)
                       String path,
                       @StaticParameter(value="file",use=Data)
                       File file)

TODO: Javadoc

Parameters:

path -

file -

toString

public String toString()

Overrides:

toString in class Object

unloadNagiosProperties

private void unloadNagiosProperties()
