Class PropertiesConsumer

java.lang.Object
  wt.util.Consumer
      wt.util.FileConsumer
          wt.util.PropertiesConsumer

All Implemented Interfaces:

Iterator

public final class PropertiesConsumer

extends FileConsumer

Creates an iteration over a list of properties files, without buffering all the properties files first. The files are processed just as properties files are, with the one exception that duplicate keys ARE returned. The expectation is that the caller will have its own handling of duplicate keys.

Supported API: false
Extendable: false

Nested Class Summary

protected static class
