Connection Class Reference

Handles communication between server and this client. User must use connect method to connect server. After that user can use rest of the methods to manage connection. Also user should handle most of events, but atleast connectionupdatedevent. More...

void ChangePriority	(	Assignment	assignment,
		Assignment.priorities	priority
	)

Chances priority to currentconnetion and then updates that to connectionslist and finaly to server. It makes the connection in new thread so it won't block ui thread.

Parameters

assignment	Assignment that needs updating
priority	Priority that assignment is to bee changed.

)

Creates receiver and connects to server with wcf and udp.

Returns

ObservableCollection of connections as assignments.

ObservableCollection<Assignment> ConvertConnectionsToAssigments

(

ConnectionDto[]

Connections

)

Converts ConnectionDto to Assignment. If location is not set, uses null and do not assign accuracymeters or time from location. If device info is empty, uses empty DeviceInfoDto.

Parameters

Connection

ConnectionDto that needs converting to Assigment

Returns

Converted Assigment

bool Disconnect

(

)

Disconnects from server.

Returns

True when disconnect goes without error and false if there is any error.

ObservableCollection<Assignment> GetAllConnections

(

)

Should be used only one time to save localy and then use ActiveConnectionsUpdated to update those. Userconnection and converts server response to assignment list.

Returns

ObservableCollection of all connections as Assignment

bool IsConnected

(

)

Is Connection on.

Returns

Boolean of is connection established.

async Task PingAsync

(

int

interval

)

Parameters

interval

ping interval in seconds

Returns

task

void ProcessAssignment

(

object

assignment

)

Changes assignments state to in progress to server. First it search right connection using guid and then makes the connection currentconnection.

Parameters

assignment

Assignment that is to be set as in progress

bool Reconnect

(

)

Reconnects to server.

Returns

True when reconnect goes without error and false if there is any error.

void RequestAction

(

RemoteActionDto

action

)

Requests action for current userconnection for currentconnection with given action. CurrentConnection needed or this does nothing.

Parameters

action

What user wants action to be

void RequestAudioVideoMedia

(

)

Makes new thread to request audio video so it won't block ui thread.

void RequestMeasurementData

(

MeasurementInstrumentDto

instrument

Parameters

instrument

Instrument that provides data

void SendTextMessage

(

String

message

)

Makes new thread to send message to server so it won't block ui thread.

Parameters

message

Message to be send

bool UdpSendMedia	(	MediaInformation	mediaInfo,
		byte[]	data,
		int	originalLength
	)

Parameters

mediaInfo	Description of the media
data	Bytes constituting the media data
originalLength	Length of the media prior to encoding for such encodings that require the length for decompression.

Returns

True, if data queued for sending, otherwise false
