Description 

 

ClientException 

Base class for all exceptions directly thrown by library methods.  

 

ConnectionConstraints 

Collects the constraints to be applied on the overall data flow from the Connection. They can only be used in order to restrict the constraints set by Lightstreamer Server Metadata Adapter.
Currently, only a constraint on the bandwidth is supported.
 

 

ConnectionInfo 

Collects the parameters related to a connection request to Lightstreamer server.  

 

ExtendedTableInfo 

Contains the specification of a table to be subscribed to Lightstreamer Server. All the items and fields in the table are supplied. Group and Schema names to be sent to the Server are made by space separated concatenations of item and field names. This name convention is suitable for a Metadata Adapter derived from LiteralBasedProvider or equivalent to it.  

 

LSClient 

Encapsulates a single connector to Lightstreamer Server. 

 

MessageInfo 

A message object that will be sent to a Lightstreamer Server through a call to LSClient.SendMessage The class contains the message string, the sequence to which such message is associated and a timeout to wait before the server declares lost the previous message in sequence.  

 

PushConnException 

Thrown when the connection to Lightstreamer Server cannot be established or in case of abnormal connection termination. It can be received both in a synchronous and an asynchronous way.  

 

PushServerException 

Thrown in case of an unexpected answer or error condition received from Lightstreamer Server. A detailed error code is supplied, to support automatic recovery actions. It can be received both in a synchronous and an asynchronous way. In normal operation, this exception should never be received.  

 

PushUserException 

Thrown in case the Server refuses to satisfy a request because of the constraints imposed by the Metadata Adapter or by Server configuration. A detailed error code is supplied. Both the error code and the message are received from the Server. In particular:
- A positive error code is issued by the Server after checking the request against the constraints imposed by the Metadata Adapter or by its own configuration. See the text protocol documentation for a reference of the error codes that can be issued in response to stream/poll requests.
- A zero or negative error code is issued... more 

 

SimpleTableInfo 

Contains the specification of a table to be subscribed to Lightstreamer Server.  

 

SubscrException 

Thrown if a subscription or unsubscription specification is not correct or the request cannot be executed for some reason. 

 

SubscribedTableKey 

Key object to be used to unsubscribe tables. 

 

SubscriptionConstraints 

Collects constraints to be applied on a subscription, to change the currently set parameters for all the involved items. They can only be used in order to restrict the constraints set by Lightstreamer Server Metadata Adapter.
Currently, only a constraint on the maximum update frequency is supported.
