Detailed Description

This class encapsulates an IPv4 address.

Member Function Documentation

BZRead()

int Dwm::Ipv4Address::BZRead ( BZFILE *  bzf )

virtual

Reads from a BZFILE pointer.

Returns the number of bytes read (4 on success).

Implements Dwm::BZ2Readable.

BZWrite()

int Dwm::Ipv4Address::BZWrite ( BZFILE *  bzf ) const

virtual

Writes to a BZFILE pointer.

Returns the number of bytes written (4 on success).

Implements Dwm::BZ2Writable.

IpSum()

uint32_t Dwm::Ipv4Address::IpSum

(

)

const

Returns the partial sum of the IP address, as would be used when calculating the IP header checksum or UDP checksum (as part of the 'pseudo-header' used for UDP checksums).

operator+=()

Ipv4Address& Dwm::Ipv4Address::operator+= ( uint32_t  i )

inline

+= operator.

Protects against roll-over (will not increment past 255.255.255.255). Note that the right hand side must be in host byte order.

Here is the call graph for this function:

operator-=()

Ipv4Address& Dwm::Ipv4Address::operator-= ( uint32_t  i )

inline

-= operator.

Protects against roll-under (will not decrement past 0.0.0.0). Note that the right hand side must be in host byte order.

Raw()

ipv4addr_t Dwm::Ipv4Address::Raw ( ) const

inline

Returns an ipv4addr_t representation (32-bit value in network byte order).

Read() [1/2]

ssize_t Dwm::Ipv4Address::Read ( int  fd )

virtual

Reads from a file descriptor.

Returns the number of bytes read (4 on success).

Implements Dwm::Readable.

Read() [2/2]

int Dwm::Ipv4Address::Read ( gzFile  gzf )

virtual

Reads from a gzFile.

Returns the number of bytes read (4 on success).

Implements Dwm::GZReadable.

StreamedLength()

uint32_t Dwm::Ipv4Address::StreamedLength ( ) const

virtual

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

Implements Dwm::Writable.

Write() [1/2]

ssize_t Dwm::Ipv4Address::Write ( int  fd ) const

virtual

Writes to a file descriptor.

Returns the number of bytes written (4 on success).

Implements Dwm::Writable.

Write() [2/2]

int Dwm::Ipv4Address::Write ( gzFile  gzf ) const

virtual

Writes to a gzFile.

Returns the number of bytes written (4 on success).

Implements Dwm::GZWritable.
