SYNOPSIS

Namespaces

tools
This namespace is for the libtool library.

Data Structures

struct Command
Used by contexts for callbacks (to run code using a mutex).
class Context
Provides a context for configuration.
class ContextPolicyIs
Needed by the user to set one of the policies.
class Coordinator
Thread safe coordination of ThreadContext per Threads.
class DefaultGetPolicy
Implements lookup with spec.
class DefaultSetPolicy
Implements creating user/ key when key is not found.
class Discriminator
This technique with the PolicySelector and Discriminator is taken from the book 'C++ Templates - The Complete Guide' by David Vandevoorde and Nicolai M.
class GetPolicyIs
Needed by the user to set one of the policies.
class KDB
Constructs a class KDB.
class Key
Key is an essential class that encapsulates key name , value and metainfo .
class KeySet
A keyset holds together a set of keys.
class KeySetIterator
For C++ forward Iteration over KeySets.
class KeySetReverseIterator
For C++ reverse Iteration over KeySets.
class Layer
Base class for all layers.
class LockPolicyIs
Needed by the user to set one of the policies.
class NameIterator
For C++ forward Iteration over Names.
class NameReverseIterator
For C++ reverse Iteration over Names.
class none_t
This type is being used as bottom type that always fails.
class ObserverPolicyIs
Needed by the user to set one of the policies.
struct PerContext
A data structure that is stored by context inside the Coordinator.
class SetPolicyIs
Needed by the user to set one of the policies.
class ThreadSubject
Subject from Observer pattern for ThreadContext.
struct Va
Needed to avoid constructor ambiguity.
class ValueObserver
Base class for values to be observed.
class WritePolicyIs
Needed by the user to set one of the policies.

Typedefs

typedef std::unordered_map< std::string, LayerAction > LayerMap
A vector of layers.

Functions

bool operator< (ValueObserver const &lhs, ValueObserver const &rhs)
Needed to put a ValueObserver in a map.
std::ostream & operator<< (std::ostream &os, kdb::Key const &k)
Stream the name of a key.
std::istream & operator>> (std::istream &is, kdb::Key &k)
Reads a line with a keys name.
std::ostream & operator<< (std::ostream &os, kdb::KeySet const &cks)
Outputs line per line the keynames.
std::istream & operator>> (std::istream &is, kdb::KeySet &ks)
Reads line per line key names and appends those keys to ks.

Detailed Description

This is the main namespace for the C++ binding and libraries.

Classes or Functions directly below this namespace are header-only. Sub namespaces are intended for libraries and you need to link the library if you want to use them.

Function Documentation

bool kdb::operator< (ValueObserver const & lhs, ValueObserver const & rhs)

Needed to put a ValueObserver in a map.

Returns:

Comparision result

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
