# Method: staticIfaceAddressChanged
# Invoked when the address of an static network interface is going to
# be changed, this method receives the old and new addresses and masks
# as arguments. Returning a true value means that this
# module's configuration would become inconsistent if such a change
# was made. In that case the network module will not make the change,
# but warn the user instead. You should override this method if you need
# to.
#
# Parameters:
#
# iface - interface name
# oldaddr - old address
# oldmask - old mask
# newaddr - new address
# newmask - new mask
#
# Returns:
#
# boolean - true if module's configuration becomes inconsistent, otherwise
# false
sub staticIfaceAddressChanged # (iface, oldaddr, oldmask, newaddr, newmask)
{
return undef;
}
# Method: staticIfaceAddressChangedDone
#
# Invoked when the change in the adddress of a static inteface has taken
# place.
#
# Iit will be called after freeIface, ifaceMethodChanged and staticIfaceAddressChanged
# when the configuration changes have already been set.
#
# Parameters:
#
# iface - interface name
# oldaddr - old address
# oldmask - old mask
# newaddr - new address
# newmask - new mask
#
sub staticIfaceAddressChangedDone # (iface, oldaddr, oldmask, newaddr, newmask)
{
# default empty implementation. Subclasses should override this as
# needed.
}
# Method: ifaceMethodChanged
#
# Invoked when the configuration method for a network interface is
# going to change. Both the old and new methods are passed as
# arguments to this function. They are strings: static, dhcp,
# trunk or notset. As with the previous function, a return value of
# true will prevent the change from being made. You should override this
# method if you need to.
#
# Parameteres:
#
# iface - interface name
# oldmethod - old method
# newmethod - newmethod
#
# Returns:
#
# boolean - true if module's configuration becomes inconsistent, otherwise
# false
sub ifaceMethodChanged # (iface, oldmethod, newmethod)

# Method: ifaceMethodChangeDone
#
# Invoked when a method configuration change has taken place.
#
# Note that it will be called after freeIface and ifaceMethodChanged
# when the configuration changes have already been set.
#
# Parameteres:
#
# iface - interface name
#
sub ifaceMethodChangeDone # (iface)
{
# default empty implementation. Subclasses should override this as
# needed.
}
# Method: ifaceExternalChanged
#
# Invoked when a iface is going to change from external to
# internal and viceversa. Its argument is the name of the real
# interface. As with the previous function, a return value of
# true will prevent the change from being made. You should override this
# method if you need to.
#
# Parameteres:
#
# iface - interface name
#
# external - boolean indicating if the property is gonna set to
# *external*
#
# Returns:
#
# boolean - true if module's configuration becomes inconsistent, otherwise
# false
sub ifaceExternalChanged # (iface)

# Method: vifaceDelete
#
# Invoked when a virtual interface is going to be removed. Its
# arguments are the real interface which it's going to be removed from,
# the name of the interface to remove, its ip address and its netmask. It
# works the same way: return true if the removal of the virtual
# interface is incompatible with your module's current configuration.
#
# Parameteres:
#
# iface - interface name
# viface - virtual interface to be removed
#
# Returns:
#
# boolean - true if module's configuration becomes inconsistent, otherwise
# false
#
sub vifaceDelete # (iface, viface)

# Method: vifaceAdded
#
# Invoked when a new virtual interface is going to be created. Its
# arguments are the real interface to which it's going to be added,
# the name of the new interface, its ip address and its netmask. It
# works the same way: return true if the creation of the virtual
# interface is incompatible with your module's current configuration.
#
# Parameteres:
#
# iface - interface name
# viface - virtual interface to be removed
# newmethod - newmethod
#
# Returns:

# boolean - true if module's configuration becomes inconsistent, otherwise
# false

# Method: changeIfaceExternalProperty
#
# Invoked when an interface is going to change from external to
# internal. Its argument is the name of the real interface. It
# works exactly the same way as two methods above.
#
# Parameters:
#
# iface - interface name
# external - boolean indicating in which way external is going to change
#
# Returns:
#
# boolean - true if module's configuration becomes inconsistent, otherwise
# false
#

# Method: freeIface
#
# Invoked when an interface is going to be removed. Its argument
# is the name of the real interface. It works exactly
# the same way as the three methods above.
#
# Parameteres:
#
# iface - interface name
#
sub freeIface # (iface)
{
# default empty implementation. Subclasses should override this as
# needed.
}
# Method: freeViface
#
# Invoked when a virtual interface is going to be removed. Its arguments
# are the names of the real and virtual interfaces. It works exactly
# the same way as the four methods above.
#
# Parameteres:
#
# iface - interface name
# viface - virtual interface to be removed
#

# needed.
}
# Method: gatewayDelete
#
# Invoked when a gateway is going to be removed.
# It works the same way: return true if the removal of the gateway
# is incompatible with your module's current configuration.
#
# Parameteres:
#
# gwName - gateway name
#
# Returns:
#
# boolean - true if module's configuration becomes inconsistent,
# false otherwise
#

# Method: regenGatewaysFailover
