/**
* Explicit equals method to compare the 'match' for flows stored in the data-stores and flow fetched from the switch.
- * Usecase: e.g If user don't set any ethernet source and destination address for match,data store will store null for
- * these address.
- * e.g [_ethernetMatch=EthernetMatch [_ethernetDestination=null, _ethernetSource=null, _ethernetType=
- * EthernetType [_type=EtherType [_value=2048], _mask=null, augmentation=[]]
+ * Flow installation process has three steps
+ * 1) Store flow in config data store
+ * 2) and send it to plugin for installation
+ * 3) Flow gets installed in switch
+ *
+ * The flow user wants to install and what finally gets installed in switch can be slightly different.
+ * E.g, If user installs flow with src/dst ip=10.0.0.1/24, when it get installed in the switch
+ * src/dst ip will be changes to 10.0.0.0/24 because of netmask of 24. When statistics manager fetch
+ * stats it gets 10.0.0.0/24 rather then 10.0.0.1/24. Custom match takes care of by using masked ip
+ * while comparing two ip addresses.
*
- * But when you fetch the flows from switch, openflow driver library converts all zero bytes of mac address in the
- * message stream to 00:00:00:00:00:00. Following string shows how library interpret the zero mac address bytes and
- * eventually when translator convert it to MD-SAL match, this is how it looks
- * [_ethernetDestination=EthernetDestination [_address=MacAddress [_value=00:00:00:00:00:00], _mask=null, augmentation=[]],
- * _ethernetSource=EthernetSource [_address=MacAddress [_value=00:00:00:00:00:00], _mask=null, augmentation=[]],
- * _ethernetType=EthernetType [_type=EtherType [_value=2048], _mask=null, augmentation=[]]
+ * Sometimes when user don't provide few values that is required by flow installation request, like
+ * priority,hard timeout, idle timeout, cookies etc, plugin usages default values before sending
+ * request to the switch. So when statistics manager gets flow statistics, it gets the default value.
+ * But the flow stored in config data store don't have those defaults value. I included those checks
+ * in the customer flow/match equal function.
*
- * So this custom equals method add additional check, in case any match element is null in data-store-flow, but not
- * in the flow fetched from switch.
*
* @param statsFlow
* @param storedFlow
* @return
