Class DataRecordSource

java.lang.Object
  com.partnersoft.data.DataRecordSource

All Implemented Interfaces:

Coggable, java.lang.Iterable<Naming>

Direct Known Subclasses:

StreamingDataRecordSource, TurtleOutageSource

public abstract class DataRecordSource
extends java.lang.Object
implements Coggable, java.lang.Iterable<Naming>

A source for data records, represented as an iteration of Namings. Usually the data is tabular; each record has the same keys. However, the addition of optional transforms can muddy this a bit. Here is an example of use:

 DataSourceMap source = new DataSourceMapSubclass();
 Iterator it = source.iterator();
 while (it.hasNext()) {
    Naming current = (Naming)it.next();
    Log.info("field value = " + current.getValue("field"));
    }
