Class Hierarchy
This inheritance list is sorted roughly, but not completely, alphabetically:
[detail level 123]
 CAdvertiseOptionsA class for customizing the publication options for a topic or service advertised. E.g.: Set the scope of a topic/service
 CAdvertiseMessageOptionsA class for customizing the publication options for a topic advertised. E.g.: Set the rate of messages per second published
 CAdvertiseServiceOptionsA class for customizing the publication options for a service advertised
 CBatchHolds the result of a query for messages
 CClockA Clock interface for time tracking
 CNetworkClockA Clock interface implementation that uses gz::msgs::Clock messages distributed across the network
 CWallClockA Clock implementation that leverages host OS time APIs
 CDescriptorMeta-information about what a log contains. This may be useful for determining QueryOptions or for generating a high-level overview of a Log's contents
 CDiscovery< Pub >A discovery class that implements a distributed topic discovery protocol. It uses UDP multicast for sending/receiving messages and stores updated topic information. The discovery clients can request the discovery of a topic or the advertisement of a local topic. The discovery uses heartbeats to track the state of other peers in the network. The discovery clients can register callbacks to detect when new topics are discovered or topics are no longer available
 CNodeShared::HandlerInfoHandlerInfo contains information about callback handlers which is useful for local publishers and message receivers. You should only retrieve a HandlerInfo by calling CheckHandlerInfo(const std::string &_topic) const
 CNodeShared::SubscriberInfoThis struct provides information about the Subscribers of a Publisher. It should only be retrieved using CheckSubscriberInfo(const std::string&, const std::string&) const. The relevant subscriber info is a superset of the relevant HandlerInfo so we extend that struct
 CHandlerStorage< T >Class to store and manage service call handlers
 CHandlerStorage< gz::transport::IRepHandler >
 CHandlerStorage< gz::transport::IReqHandler >
 CHandlerStorage< gz::transport::ISubscriptionHandler >
 CHandlerStorage< gz::transport::RawSubscriptionHandler >
 CNodeShared::HandlerWrapperThis struct wraps up the two different types of subscription handlers: normal (deserialized) and raw (serialized). This wrapper keeps the two sets of subscription handlers coordinated while allowing them to act independently when necessary
 CIRepHandlerInterface class used to manage a replier handler
 CRepHandler< Req, Rep >With the service response
 CIReqHandlerInterface class used to manage a request handler
 CReqHandler< Req, Rep >It creates a reply handler for the specific protobuf messages used. 'Req' is a protobuf message type containing the input parameters of the service request. 'Rep' is a protobuf message type that will be filled with the service response
 CReqHandler< google::protobuf::Message, google::protobuf::Message >
 CLogInterface to a log file
 CMessageRepresents a message in a bag file
 CMessageInfoA class that provides information about the message received
 CMsgIterImplements iterator for reading messages
 CNodeA class that allows a client to communicate with other peers. There are two main communication modes: pub/sub messages and service calls
 CNodeOptionsA class for customizing the behavior of the Node. E.g.: Set a custom namespace or a partition name
 CNodeSharedPrivate data for the Node class. This class should not be directly used. You should use the Node class
 CParameterResultThe return type used in all falible parameters methods
 CParametersInterfaceCommon interface, implemented by ParametersRegistry (local updates) and by ParametersClients (remote requests)
 CParametersClientAllow to get, set, declare or list parameters
 CParametersRegistryProvides a parameter registry. Parameters can be declared, get or set in the registry. It also provides services, so the parameters can be get, set or listed from other processes
 CPlaybackInitiates playback of Gazebo Transport topics This class makes it easy to play topics from a log file
 CPlaybackHandleHandles the playback of Gazebo Transport topics. This class allows you to manage a log playback once it has started. You must hang onto the PlaybackHandle or else the playback will end early
 CNode::PublisherA class that is used to store information about an advertised publisher. An instance of this class is returned from Node::Advertise, and should be used in subsequent Node::Publisher::Publish calls
 CPublisherThis class stores all the information about a publisher. It stores the topic name that publishes, addresses, UUIDs, scope, etc
 CMessagePublisherThis class stores all the information about a message publisher
 CServicePublisherThis class stores all the information about a service publisher
 CQualifiedTimeSince time is continuous, it may be difficult to know the exact time stamp of a desired message. The QualifiedTime class provides a way to tailor how a time stamp is interpreted by the message query
 CQualifiedTimeRangePair of qualified times that represent a range. This is used to specify a desired time range to the BasicQueryOptions class
 CQueryOptionsThe QueryOptions interface is used by Log::QueryMessages() to determine which messages are retrieved from the log file
 CAllTopicsQuery for all the topics
 CTopicListSpecify a list of topics to query
 CTopicPatternSpecify a pattern of topics to query
 CRecorderRecords Gazebo Transport topics This class makes it easy to record topics to a log file. Responsibilities: topic name matching, time received tracking, multiple thread safety, subscribing to topics
 CReqHandler< google::protobuf::Message >Template specialization for google::protobuf::Message. This is only used by some gz command line tools
 CSqlParameterA class which contains a SQL statement parameter. SqlParameter can be useful for keeping SQL queries sanitized and avoid SQL injection. With C++17, it may be desirable to replace this class with std::variant
 CSqlStatementA statement for a SQL query. These are generated by the QueryOptions class to control how messages get queried from the log
 CStatisticsComputes the rolling average, min, max, and standard deviation for a set of samples
 CSubscribeOptionsA class to provide different options for a subscription
 CSubscribeOpts
 CSubscriptionHandlerBaseSubscriptionHandlerBase contains functions and data which are common to all SubscriptionHandler types
 CISubscriptionHandlerInterface class used to manage generic protobuf messages
 CSubscriptionHandler< T >It creates a subscription handler for a specific protobuf message. 'T' is the Protobuf message type that will be used for this particular handler
 CSubscriptionHandler< ProtoMsg >Specialized template when the user prefers a callbacks that accepts a generic google::protobuf::message instead of a specific type
 CRawSubscriptionHandler
 CTimeRangeOptionBase class which manages the time range settings for the native QueryOptions classes
 CAllTopicsQuery for all the topics
 CTopicListSpecify a list of topics to query
 CTopicPatternSpecify a pattern of topics to query
 CTopicStatisticsEncapsulates statistics for a single topic. The set of statistics include:
 CTopicStorage< T >Store address information about topics and provide convenient methods for adding new topics, removing them, etc
 CTopicStorage< gz::transport::MessagePublisher >
 CTopicStorage< Pub >
 CTopicUtilsThis class provides different utilities related with topics
 CUuidA portable class for representing a Universally Unique Identifier
