Method Detail

main

public static void main(String[] args)

This program must be started with the following System property:
-Dvendor.classname=
it will instantiate the subclass supplied by the vendor using
Class.forName(System.getProperty("vendor.classname")).newInstance();
this main method expects the following arguments:
-startid
the starting value for the market update tick ids -startrow
the row of the file from which the loader instance starts submitting xml rows to the vendorPublishingAPI
-endrow
the row of the file at which the loader instance stops submitting xml rows to the vendorPublishingAPI

The following settings:
-startrow 100 -endrow 1000
result in the loader starting to submit data at row 100 and stopping the submission of data at row 1001 (row 1000 is submitted)
-rate
rate / second measured of passing xml rows to the vendorPublishingAPI
filename the name of the file containing the xml data
The first thing the main method does is call the vendorInit(Stringt [] args) method implemented by the vendor

Throws:

Throwable

vendorPublishingAPI

protected abstract void vendorPublishingAPI(String xml)
                                     throws Throwable

to be implemented by vendor:
This method accepts the xml row containing a single trade as a String and does what it needs to do to cache that trade in the vendor's cache

Throws:

Throwable

easyPumpMarketChanges

protected void easyPumpMarketChanges()

this method uses the various arguments to the main method to pump trades through the vendorPublishingAPI
