Detailed Description

Contains LogManager implementation classes.

Namespaces

namespace LogManager::Exceptions

Contains exceptions LogManager classes may throw.

Classes

class ConnectionInfo

The ConnectionInfo contains parameters needed to establish a database connection. More...

class Event

The Event struct represents a single logged event. For example, CDPAlarm Set or CDPAlarm Clear. More...

class EventQuery

The EventQuery class contains the arguments for querying events from the database using LogReader. More...

class Keyframe

The Keyframe represents one row in the database or in the query result. More...

class KeyframeData

The KeyframeData represents a single logged value in some time period. More...

class LogManagerFactory

The LogManagerFactory creates readers and writers supporting CDPCompactDatastore format. More...

class LogReader

The LogReader interface is used to read data from a datastore. More...

class NodeInfo

The NodeInfo class describes a logged node and is used to match node id, name and path. More...

class TagInfo

The TagInfo class describes a tag associated with a logged node. More...

Type Documentation

typedef LogManager::EventData

Event data is a map of key-value pairs describing the event.

Unlike EventSenderTags, the event data will change during logging - it can be different for each event.

typedef LogManager::EventSenderTags

A map of event sender names to tags associated with the sender.

The event sender tags are static and will not change during logging.

typedef LogManager::IDList

List of logged node IDs.

typedef LogManager::KeyframeList

A list of Keyframe objects (rows). Can be thought of as a table.

typedef LogManager::NameList

List of logged node names.

typedef LogManager::NodeID

Used to hold the id of the logged node.

typedef LogManager::NodeInfoList

List of logged nodes.

typedef LogManager::TagMap

A map of tags associated with the node. For example, the "Unit" or "Description" of the logged node.

For each tag both the value and the source of the information is stored.

Function Documentation

IDList LogManager::ToIDList(const NodeInfoList &nodeInfoList)

Extracts node IDs from NodeInfoList. Useful when using LogReader to query data.

NameList LogManager::ToNameList(const NodeInfoList &nodeInfoList)

Extracts node names from NodeInfoList. Useful when using LogReader to query data.

bool LogManager::operator!=(const Event &lhs, const Event &rhs)

Returns true if two events are not equal.

bool LogManager::operator!=(const EventQuery::Condition &lhs, const EventQuery::Condition &rhs)

Returns true if lhs and rhs are not equal.

bool LogManager::operator!=(const EventQuery &lhs, const EventQuery &rhs)

Returns true if lhs and rhs are not equal.

bool LogManager::operator!=(const Keyframe &lhs, const Keyframe &rhs)

Returns true if lhs and rhs are not equal.

bool LogManager::operator!=(const KeyframeData &lhs, const KeyframeData &rhs)

Returns true if lhs and rhs are not equal.

bool LogManager::operator!=(const NodeInfo &lhs, const NodeInfo &rhs)

Returns true if the two NodeInfo objects are not equal.

bool LogManager::operator!=(const TagInfo &lhs, const TagInfo &rhs)

Returns true if the two NodeInfo objects are not equal.
