Class DataRecordSource

java.lang.Object

com.partnersoft.data.DataRecordSource

All Implemented Interfaces:

Coggable, java.lang.Iterable<Naming<java.lang.Object>>

Direct Known Subclasses:

StreamingDataRecordSource

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

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"));
 }
