Function Documentation

std::ostream& kdb::operator<< ( std::ostream &  os, kdb::Key const &  k  )

inline

Stream the name of a key.

If you also want to stream the value, use the plugin framework.

Parameters

os	the stream to write to
k	the key which name should be streamed

Returns

the stream

std::ostream& kdb::operator<< ( std::ostream &  os, kdb::KeySet const &  cks  )

inline

Outputs line per line the keynames.

To output values you should use the plugin framework.

Parameters

os	the stream to write to
cks	the keyset which should be streamed

Use unsetf(std::ios_base::skipws) or use noskipws iomanip on the stream if you want a null terminated sequence of key names.

Use setf(std::ios_base::unitbuf) on the stream if you want to flush the buffer after each key.

Returns

the stream

std::istream& kdb::operator>> ( std::istream &  is, kdb::Key &  k  )

inline

Reads a line with a keys name.

Parameters

is	the stream to read from
k	the key whose name will be set

Use unsetf(std::ios_base::skipws) on the stream if the keyname is terminated with an null character and not a newline.

Returns

the stream

std::istream& kdb::operator>> ( std::istream &  is, kdb::KeySet &  ks  )

inline

Reads line per line key names and appends those keys to ks.

To input values you need to use the plugin framework.

Parameters

is	the stream to read from
ks	the keyset to append to

Returns

the stream
