Constructor Detail

TelemetryChannelBase

public TelemetryChannelBase()

TelemetryChannelBase

public TelemetryChannelBase(java.lang.String endpointAddress,
                            boolean developerMode,
                            int maxTelemetryBufferCapacity,
                            int sendIntervalInMillis)

Ctor

Parameters:

endpointAddress - Must be empty string or a valid uri, else an exception will be thrown

developerMode - True will behave in a 'non-production' mode to ease the debugging

maxTelemetryBufferCapacity - Max number of Telemetries we keep in the buffer, when reached we will send the buffer Note, value should be between TRANSMIT_BUFFER_MIN_TIMEOUT_IN_MILLIS and TRANSMIT_BUFFER_MAX_TIMEOUT_IN_MILLIS inclusive

sendIntervalInMillis - The maximum number of milliseconds to wait before we send the buffer Note, value should be between MIN_MAX_TELEMETRY_BUFFER_CAPACITY and MAX_MAX_TELEMETRY_BUFFER_CAPACITY inclusive

TelemetryChannelBase

public TelemetryChannelBase(java.lang.String endpointAddress,
                            java.lang.String maxTransmissionStorageCapacity,
                            boolean developerMode,
                            int maxTelemetryBufferCapacity,
                            int sendIntervalInMillis,
                            boolean throttling,
                            int maxInstantRetries)

TelemetryChannelBase

public TelemetryChannelBase(java.util.Map<java.lang.String,java.lang.String> namesAndValues)

This Ctor will query the 'namesAndValues' map for data to initialize itself It will ignore data that is not of its interest, this Ctor is useful for building an instance from configuration

Parameters:

namesAndValues - - The data passed as name and value pairs

Method Detail

initialize

protected void initialize(java.lang.String endpointAddress,
                          java.lang.String maxTransmissionStorageCapacity,
                          boolean developerMode,

getTransmitterFactory

protected TransmitterFactory<T> getTransmitterFactory()

isDeveloperMode

public boolean isDeveloperMode()

Gets value indicating whether this channel is in developer mode.

Specified by:

isDeveloperMode in interface TelemetryChannel

Returns:

The developer mode.

setDeveloperMode

public void setDeveloperMode(boolean developerMode)

Sets value indicating whether this channel is in developer mode. If true, this also forces maxTelemetriesInBatch to be 1 (affects TelemetryBuffer).

Specified by:

setDeveloperMode in interface TelemetryChannel

Parameters:

developerMode - true or false

stop

public void stop(long timeout,
                 java.util.concurrent.TimeUnit timeUnit)

Specified by:

stop in interface TelemetryChannel

Parameters:

timeout - Time to try and stop

timeUnit - The units of the 'timeout' parameter

setTransmitBufferTimeoutInSeconds

public void setTransmitBufferTimeoutInSeconds(int transmitBufferTimeoutInSeconds)

Sets the time tow wait before flushing the internal buffer

Parameters:

transmitBufferTimeoutInSeconds - should be between MIN_FLUSH_BUFFER_TIMEOUT_IN_SECONDS and MAX_FLUSH_BUFFER_TIMEOUT_IN_SECONDS inclusive if the number is lower than the minimum then the minimum will be used if the number is higher than the maximum then the maximum will be used

setMaxTelemetriesInBatch

public void setMaxTelemetriesInBatch(int maxTelemetriesInBatch)

Sets the buffer size

Parameters:

maxTelemetriesInBatch - should be between MIN_MAX_TELEMETRY_BUFFER_CAPACITY and MAX_MAX_TELEMETRY_BUFFER_CAPACITY inclusive if the number is lower than the minimum then the minimum will be used if the number is higher than the maximum then the maximum will be used

flush

public void flush()

Flushes the data that the channel might have internally.

Specified by:

flush in interface TelemetryChannel

setSampler

public void setSampler(TelemetrySampler telemetrySampler)

Sets an optional Sampler that can sample out telemetries Currently, we don't allow to replace a valid telemtry sampler.

Specified by:

setSampler in interface TelemetryChannel

Parameters:

telemetrySampler - - The sampler

send

public void send(Telemetry telemetry)

Sends a Telemetry instance through the channel.

Specified by:

send in interface TelemetryChannel

Parameters:

makeSureEndpointAddressIsValid

protected void makeSureEndpointAddressIsValid(java.lang.String endpointAddress)

The method will throw IllegalArgumentException if the endpointAddress is not a valid URI. Please note that a null or empty string is valid as far as the class is concerned and thus considered valid

Parameters:

endpointAddress -

Throws:

java.lang.IllegalArgumentException - if the endpointAddress is invalid
