Direct Known Subclasses:: GeometryChangeOperation, TagChangeOperation

public abstract class CooperativeChallengeOperation
extends java.lang.Object

This represents an operation that is embedded in a cooperative challenge. Example: Given a FeatureCollection geojson uploaded to MapRoulette:
For Tag changes:

 {
   "type": "FeatureCollection",
   "features": [ ... ],            // omitted for readability
   "cooperativeWork": {            // special `cooperativeWork` property
     "meta": {
       "version": 2,               // must be format version `2`
       "type": 1                   // `1` for tag fix type
     },
     "operations": [               // Operations section (see below)
       ...
     ]
   }
 }

For geometry changes:

 {
   "type": "FeatureCollection",
   "features": [ ... ],            // omitted for readability
   "cooperativeWork": {            // special `cooperativeWork` property
     "meta": {
       "version": 2,               // must be format version `2`
       "type": 2                   // `2` for change file type
     },
     "file": {                     // Operations section (see below)
       "type": "xml",              // only xml is supported at this time
       "format": "osc",            // only osc is supported at this time
       "encoding": "base64",       // only base64 is supported at this time
       "content": "..."            // The base64 encoded OSC file
     }
   }
 }

This class is an abstract representation of the json material to be found under "operations". Its subclasses should handle the various ChangeDescriptor types, including GeometryChangeDescriptor, LongElementChangeDescriptor, RelationMemberChangeDescriptor, TagChangeDescriptor
