 Classes
Classes
        | Class | Description | |
|---|---|---|
|   | ChannelDefinition | Represents a channel definition in a PQDIF file. The channel definition resides within a DataSourceRecord and defines a ChannelInstance. | 
|   | ChannelInstance | Represents a channel instance in a PQDIF file. See IEEE 1159.3-2019 section 5.4.3 for details. A channel instance resides in an ObservationRecord, and is defined by a ChannelDefinition inside the observation record's DataSourceRecord. | 
|   | ChannelSetting | Represents a channel setting in a PQDIF file. A channel setting resides in an MonitorSettingsRecord, and is defined by a ChannelDefinition inside the observation record's DataSourceRecord. | 
|   | ContainerRecord | Represents the container record in a PQDIF file. There can be only one container record in a PQDIF file, and it is the first physical Record. | 
|   | DataSourceRecord | Represents a data source record in a PQDIF file. The data source record contains information about the source of the data in an ObservationRecord. | 
|   | DataSourceType | Types of data sources. | 
|   | DisturbanceCategory | Disturbance Categories (as defined in IEEE 1159). | 
|   | Equipment | Power quality equipment and software. | 
|   | LogicalParser | Represents a parser which parses the logical structure of a PQDIF file. | 
|   | LogicalWriter | Represents a writer used to create files using the PQDIF file format. | 
|   | MissingTag | Represents an exception | 
|   | MonitorSettingsRecord | Represents a monitor settings record in a PQDIF file. | 
|   | ObservationRecord | Represents an observation record in a PQDIF file. | 
|   | QuantityCharacteristic | Specifies additional detail about the meaning of the series data. | 
|   | QuantityType | The high-level description of the type of quantity which is being captured by a channel. | 
|   | SeriesDefinition | Definition of a SeriesInstance. | 
|   | SeriesInstance | Represents an instance of a series in a PQDIF file. A series instance resides in a ChannelInstance and is defined by a SeriesDefinition. | 
|   | SeriesValueType | Defines tags used to identify different series value types. | 
|   | Vendor | Vendors for power quality hardware. |
