Constructor Detail

FXRatesAdapter

public FXRatesAdapter(com.caplin.datasource.DataSource dataSource)

Constructs an FXRatesAdapter that will utilise the specified DataSource and its configuration for communication with the motif.

Parameters:

dataSource - The DataSource that will be used to receive requests for ESP, SPOT, FORWARD and SWAP rates. As well as requests for prices on Broken Dates.

Method Detail

createQuotePublisher

public FXQuotePublisher createQuotePublisher(java.lang.String namespace,
                                             CachedDataProvider<RateSubjectInfo> provider,
                                             boolean sendDiscardAfterError)

Creates an FXQuotePublisher that is able to respond to messages received on the CachedDataProvider that is passed in.

Parameters:

namespace - the namespace to provide rates for, defaults are defined in RateSubjectNamespacing.DefaultNamespaces

provider - the CachedDataProvider that will receive the rate requests

sendDiscardAfterError - If set to TRUE, your CachedDataProvider will receive an immediate callback on the CachedDataProvider.onDiscard(SubjectInfo) method after you publish a failure message by calling SubjectMessagePublisher.sendNotFound(SubjectInfo). This can be useful if you want to use the same code path to clear a cache (for example) whether a subscription is ended by the client discarding it or the back end you are integrating with no longer providing the data.

Returns:

the FXQuotePublisher able to send quotes containing rates
