Member Function Documentation

close()

void Address::close ( )

overridevirtual

Close any open connections and revert to idle.

Child MUST override this method.

Implements satcat5::net::Address.

Definition at line 37 of file eth_address.cc.

iface()

satcat5::net::Dispatch * Address::iface ( ) const

overridevirtual

Fetch a pointer to the underlying interface.

Child MUST override this method.

Implements satcat5::net::Address.

Definition at line 29 of file eth_address.cc.

matches_reply_address()

bool Address::matches_reply_address ( ) const

overridevirtual

Does this Address object match the parent interface's current reply address? Multicast destinations should match any source address expected to receive the multicast message.

Child MUST override this method.

Implements satcat5::net::Address.

Definition at line 52 of file eth_address.cc.

open_write()

satcat5::io::Writeable * Address::open_write ( unsigned  len )

overridevirtual

Open a new frame to the designated address and type.

Child MUST override this method.

Returns

Zero if sending a frame is not currently possible.

Implements satcat5::net::Address.

Definition at line 33 of file eth_address.cc.

retry()

virtual void satcat5::net::Address::retry ( )

inlinevirtualinherited

If this Address is not in the ready() state, reattempt any steps required to do so, such as MAC address resolution.

Child SHOULD override this method if applicable.

Reimplemented in satcat5::udp::Address, and satcat5::ip::Address.

Definition at line 52 of file net_address.h.

save_reply_address()

void Address::save_reply_address ( )

overridevirtual

Bind this Address object to the parent interface's current reply address, as provided in net::Dispatch::open_reply().

Child MUST override this method.

Implements satcat5::net::Address.

Definition at line 62 of file eth_address.cc.

write_packet()

bool Address::write_packet ( unsigned  nbytes, const void *  data  )

inherited

All-in-one call that writes an entire packet.

Equivalent to open_write(), io::Writeable::write_bytes(), io::Writeable::write_finalize().
