Method Detail

endpoint

public SplitClientConfig.Builder endpoint(String endpoint,
                                          String eventsEndpoint)

The rest endpoint that sdk will hit for latest features and segments.

Parameters:

endpoint - MUST NOT be null

Returns:

featuresRefreshRate

public SplitClientConfig.Builder featuresRefreshRate(int seconds)

The SDK will poll the endpoint for changes to features at this period.

Implementation Note: The SDK actually polls at a random interval chosen between (0.5 * n, n). This is to ensure that SDKs that are deployed simultaneously on different machines do not inundate the backend with requests at the same interval.

Parameters:

seconds - MUST be greater than 0. Default value is 60.

Returns:

segmentsRefreshRate

public SplitClientConfig.Builder segmentsRefreshRate(int seconds)

The SDK will poll the endpoint for changes to segments at this period in seconds.

Implementation Note: The SDK actually polls at a random interval chosen between (0.5 * n, n). This is to ensure that SDKs that are deployed simultaneously on different machines do not inundate the backend with requests at the same interval.

Parameters:

seconds - MUST be greater than 0. Default value is 60.

Returns:

impressionsRefreshRate

public SplitClientConfig.Builder impressionsRefreshRate(int seconds)

The ImpressionListener captures the which key saw what treatment ("on", "off", etc) at what time. This log is periodically pushed back to split endpoint. This parameter controls how quickly does the cache expire after a write.

This is an ADVANCED parameter

Parameters:

seconds - MUST be > 0.

Returns:

impressionsQueueSize

public SplitClientConfig.Builder impressionsQueueSize(int impressionsQueueSize)

The impression listener captures the which key saw what treatment ("on", "off", etc) at what time. This log is periodically pushed back to split endpoint. This parameter controls the in-memory queue size to store them before they are pushed back to split endpoint. If the value chosen is too small and more than the default size(5000) of impressions are generated, the old ones will be dropped and the sdk will show a warning.

This is an ADVANCED parameter.

Parameters:

impressionsQueueSize - MUST be > 0. Default is 5000.

Returns:

impressionListener

public SplitClientConfig.Builder impressionListener(ImpressionListener impressionListener,
                                                    int queueSize)

You can provide your own ImpressionListener to capture all impressions generated by SplitClient. An Impression is generated each time getTreatment is called.

Note that we will wrap any ImpressionListener provided in our own implementation with an Executor controlling impressions going into your ImpressionListener. This is done to protect SplitClient from any slowness caused by your ImpressionListener. The Executor will be given the capacity you provide as parameter which is the number of impressions that can be saved in a blocking queue while waiting for your ImpressionListener to log them. Of course, the larger the value of capacity, the more memory can be taken up.

The executor will create two threads.

This is an ADVANCED function.

Parameters:

impressionListener -

queueSize - maximum number of impressions that will be queued in memory. If the impressionListener is slow, the queue will fill up and any subsequent impressions will be dropped.

Returns:

metricsRefreshRate

public SplitClientConfig.Builder metricsRefreshRate(int seconds)

The diagnostic metrics collected by the SDK are pushed back to split endpoint at this period.

This is an ADVANCED parameter

Parameters:

seconds - MUST be > 0.

Returns:

connectionTimeout

public SplitClientConfig.Builder connectionTimeout(int ms)

Http client connection timeout. Default value is 15000ms.

Parameters:

ms - MUST be greater than 0.

Returns:

Builder

readTimeout

public SplitClientConfig.Builder readTimeout(int ms)

Http client read timeout. Default value is 15000ms.

Parameters:

ms - MUST be greater than 0.

Returns:

this Builder instance

enableDebug

public SplitClientConfig.Builder enableDebug()

disableLabels

public SplitClientConfig.Builder disableLabels()

Disable label capturing

Returns:

ready

public SplitClientConfig.Builder ready(int milliseconds)

The SDK kicks off background threads to download data necessary for using the SDK. You can choose to block until the SDK has downloaded split definitions so that you will not get the 'control' treatment.

If this parameter is set to a non-negative value, the SDK will block for that number of milliseconds for the data to be downloaded.

If the download is not successful in this time period, a TimeOutException will be thrown.

A negative value implies that the SDK building MUST NOT block. In this scenario, the SDK might return the 'control' treatment until the desired data has been downloaded.

Parameters:

milliseconds - MUST BE greater than or equal to 0;

Returns:

build
