The following tables list the members exposed by EasyDAClientParameters.

Public Constructors

	Name	Description
	EasyDAClientParameters Constructor	Overloaded.

Public Fields

	Name	Description
	DefaultBrowseNodesChunk	Default value of the BrowseNodesChunk property.
	DefaultElementNameCaseSensitive	Default value of the ElementNameCaseSensitive property.
	DefaultLinkCallbackQueueSize	Default value of the LinkCallbackQueueSize property.
	DefaultRequestQueueSize	Default value of the RequestQueueSize property.
	DefaultResponseQueueSize	Default value of the ResponseQueueSize property.
	DefaultTopicProcessingIntervalTimeout	Default value of the TopicProcessingIntervalTimeout property.
	DefaultTopicProcessingTotalTimeout	Default value of the TopicProcessingTotalTimeout property.
	DefaultTopicRetrialPeriod	Default value of the TopicRetrialPeriod property.

Public Properties

	Name	Description
	BrowseNodesChunk	Number of nodes requested in one call when browsing for OPC branches or leaves.
	ClientReconnectDelay	Client reconnect delay. Number of milliseconds. If operations on specific OPC server are found to be failing, the server is disconnected, and further connection is retried only after the client reconnect delay elapses. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	ComInstantiationParameters	Contains parameters that influence instantiation of OPC servers. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	Default	Default client parameters.
	ElementNameCaseSensitive	Indicates whether the element names in the OPC server are case-sensitive. This value is used when the element name is matched with element name filter pattern for OPC-DA 1.0 and 2.0 servers that generally cannot do the element name filtering internally.
	LinkCallbackQueueSize	Size of the internal queue that holds callback data from the OPC server.
	RequestQueueSize	Size of the internal queue that holds requests related to operations on OPC items.
	ResponseQueueSize	Size of the internal queue that holds responses related to operations on OPC items.
	ServerFailedReconnectDelay	Server failed reconnect delay. Number of milliseconds. If the OPC server indicates that vendor specific fatal error has occurred within the server, the server is disconnected, and further connection is retried only after this delay elapses. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	ServerShutdownReconnectDelay	Server shutdown reconnect delay. Number of milliseconds. If the OPC server indicates that it needs to shut down, the server is disconnected, and further connection is retried only after this delay elapses. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	ServerStatusCheckPeriod	Server status check period. Number of milliseconds. Determines how often the system periodically checks the status of the OPC server (by calling IOPCServer::GetStatus method). (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	StandardName	A symbolic name of the current parameter combination if it has a standard name. Empty otherwise. (Inherited from OpcLabs.BaseLib.Parameters)
	TopicProcessingIntervalTimeout	Topic processing interval timeout. Number of milliseconds. When the incoming requests related to OPC items pause for this interval, the requests collected so far are applied to the OPC server.
	TopicProcessingTotalTimeout	Topic processing total timeout. Number of milliseconds. When the incoming requests related to OPC items are being collected for this period, the requests collected so far are applied to the OPC server.
	TopicRetrialPeriod	Topic retrial period. Number of milliseconds. Determines how often will the component run the internal process to re-connect to OPC items that have failed (e.g. due to incorrect Item IDs).

Public Methods

	Name	Description
	Clone	Overridden.
	Equals	Overloaded. Determines whether the specified EasyDAClientParameters is equal to the current object.
	GetEffectiveComInstantiationParameters	Determines the effective COM instantiation parameters. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	GetHashCode	Overridden.
	GetObjectData	Overridden.
	GetSchema	(Inherited from OpcLabs.BaseLib.Info)
	GetType	Gets the System.Type of the current instance. (Inherited from object)
	ReadXml	(Inherited from OpcLabs.BaseLib.Info)
	ToString	(Inherited from OpcLabs.BaseLib.Parameters)
	WriteXml	(Inherited from OpcLabs.BaseLib.Info)

Protected Methods

	Name	Description
	CopyFrom	Infrastructure. Copies data from the specified parameter object into the current parameter object. (Inherited from OpcLabs.BaseLib.Parameters)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from object)
	GetDefaultStandardName	Indicates the standard name for the default combination of parameters. (Inherited from OpcLabs.BaseLib.Parameters)
	GetStandardNameValues	Returns a collection of standard values for the OpcLabs.BaseLib.Parameters.StandardName property. (Inherited from OpcLabs.BaseLib.Parameters)
	MakeString	Infrastructure. (Inherited from OpcLabs.BaseLib.Parameters)
	MemberwiseClone	Creates a shallow copy of the current System.Object. (Inherited from object)
	OnPropertyChanged	Infrastructure. (Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)
	ReadXmlElement	Overridden. Infrastructure.
	WriteXmlElement	Overridden. Infrastructure.

Extension Methods

	Name	Description
	SetState<TNode>	Sets the arbitrary object associated with the node.

Public Events

	Name	Description
	PropertyChanged	(Inherited from OpcLabs.EasyOpc.Engine.EasyClientParameters)

Public Operators

Equality	Determines whether the two objects are equal.
Inequality	Determines whether the two objects are not equal.
