This PR:

  • adds support to set the DOP of individual operators, data sources, and sink. Map-based operators and data sinks inherit the DOP of their input to enable chaining, if their DOP is not explicitly specified.
  • simplifies the translation of the new Java API to the core operators.

@fhueske fhueske added this to the Release 0.5 milestone Apr 24, 2014

Your code contains a lot of these obvious comments (java's methods are usually very verbose).
