Member Function Documentation

StreamedLength()

virtual uint32_t Dwm::Writable::StreamedLength ( ) const

pure virtual

Returns the number of bytes that should be written if one of the Write() members is called.

Implemented in Dwm::Patricia< KeyType, ValueType, KeyEqual >, Dwm::Ipv4Routes< _valueT >, Dwm::Ipv4Prefix, Dwm::Ipv4TcpHeader, Dwm::Ipv4Address, Dwm::Ipv4PacketHeader, Dwm::ProcessInfo, Dwm::Rusage, Dwm::Ipv4TcpPayload, Dwm::Ipv4UdpPayload, Dwm::Ipv4UdpHeader, Dwm::Ipv4TcpPacket, Dwm::Ipv4UdpPacket, Dwm::Ipv6Prefix, Dwm::MplsLabel, Dwm::Ipv4IcmpMessage, Dwm::TimeInterval, Dwm::TimeValue, Dwm::TimeValue64, Dwm::MacAddress, Dwm::Ipv6Address, and Dwm::MplsLabelStack.

Write() [1/2]

virtual ssize_t Dwm::Writable::Write ( int  fd ) const

pure virtual

Write to a file descriptor.

Return the number of bytes written on success, -1 on failure.

Implemented in Dwm::Patricia< KeyType, ValueType, KeyEqual >, Dwm::Ipv4Routes< _valueT >, Dwm::Ipv4Address, Dwm::Ipv4Prefix, Dwm::Ipv4PacketHeader, Dwm::Ipv4TcpHeader, Dwm::ProcessInfo, Dwm::Rusage, Dwm::TimeInterval, Dwm::Ipv4UdpHeader, Dwm::TimeValue, Dwm::TimeValue64, Dwm::Ipv4TcpPayload, Dwm::Ipv4UdpPayload, Dwm::Ipv6Address, Dwm::Ipv4TcpPacket, Dwm::Ipv4UdpPacket, Dwm::Ipv6Prefix, Dwm::MplsLabel, Dwm::Ipv4IcmpMessage, Dwm::MacAddress, and Dwm::MplsLabelStack.

Write() [2/2]

virtual size_t Dwm::Writable::Write ( FILE *  f ) const

pure virtual

Write to a FILE pointer.

Return 1 on success, 0 on failure (fwrite() semantics).

Implemented in Dwm::Patricia< KeyType, ValueType, KeyEqual >, Dwm::Ipv4Routes< _valueT >, Dwm::Ipv4Address, Dwm::Ipv4Prefix, Dwm::Ipv4PacketHeader, Dwm::Ipv4TcpHeader, Dwm::ProcessInfo, Dwm::Rusage, Dwm::Ipv4UdpHeader, Dwm::Ipv4TcpPayload, Dwm::Ipv4UdpPayload, Dwm::TimeInterval, Dwm::TimeValue, Dwm::TimeValue64, Dwm::Ipv4TcpPacket, Dwm::Ipv6Address, Dwm::Ipv4UdpPacket, Dwm::Ipv6Prefix, Dwm::MplsLabel, Dwm::Ipv4IcmpMessage, Dwm::MacAddress, and Dwm::MplsLabelStack.
