<dependency>
  <groupId>com.tinkerpop</groupId>
  <artifactId>pipes</artifactId>
  <version>0.8</version>
</dependency>
  • SideEffectPipe now has signature of <S,T> instead of <S,E,T>
  • GroupCountFunctionPipe has signature of <S,K> to denote the key of its Map<K,Number> side-effect
  • Removed ComparisonFilterPipe as it is confusing and now PipeHelper has comparison support
  • Added PipeHelper.makePipeString() to have a single point where all pipe toString()s are created
  • Optimized PipeHelper.counter() and PipeHelper.fillCollection() by respecting architecture of AbstractPipe
  • Added PipeHelper.iterate() to complete drain an iterator
  • Added FluentPipeline as a utility class for fluently constructing a pipeline
  • Added RetainFilterPipe, added ExceptFilterPipe, and abstracted CollectionFilterPipe
  • Added EdgesPipe, added VerticesPipe, and abstracted GraphElementPipe
  • Renamed AggregatorPipe to AggregatePipe
  • AndFilterPipe and OrFilterPipe will automatically wrap provided pipes in a HasNextPipe
  • Generalized GroupCountPipe to have a value of Map<Object,Number> instead of Long
  • Migrated TablePipe and Table from Gremlin
  • Simplified the semantics of HasNextPipe (use Pipe.hasNext() to accomplish previous behavior)
  • Added MemoizePipe to memoize the mapping of a particular pipe
  • Simplified PipeClosure to be purely functional and now named PipeFunction
    • Renamed XXXClosurePipe to XXXFunctionPipe
  • Fixed performance issue in RangeFilterPipe and provided long ranges

Pipes 0.7 JavaDocs

  • Added support for Vertex.getOutEdges(String...) and Vertex.getInEdges(String...)
  • Updated AggregatorPipe to be fully SideEffectPipe compliant and to respect getPath()
  • Added PipeClosure to support closure-based pipes
  • Migrated all the Gremlin specific pipes to Pipes
  • Refactored package names to align with pipe semantics
  • Flipped the meaning of Filter, where true means pass, and false means filter
  • Added AggregatorPipe PipeClosure to process object prior to insertion into the aggregate collection
  • Added temporary fix for AggregatorPipe/LoopPipe phenomena
  • IfThenElsePipe now requires an elseClosure
