  • Harden the GraphAnalysis visitor API guarantees and better documentation of the APIs and their assumptions + guarantees

2.11 (Feb 14, 2017)

2.2 (Aug 25, 2016)

  • Major Feature: new suite of APIs for analyzing the graph of FlowNodes from an execution  (see package contents)
    • New FlowScanner classes, that provide utilities to iterate through, visit, or search FlowNodes in a specific order
      • See JavaDocs for more info
      • LinearScanner (walks through nodes, ignoring all but 1 branch of a parallel: very fast)
      • LinearBlockHoppingScanner - like LinearScanner but jumps over blocks (only sees preceding or inclusing nodes)

        • Provides the more complex APIs below.
    • SAX-like API to slice the graph into blocks or runs of nodes ("Chunks") and return information about them.
      • ForkScanner.visitSimpleChunks does this execution

      • ChunkFinder: defines the boundary conditions for starting & ending a chunk
        • A couple implementations included.
      • Container classes/APIs for collections of FlowNodes (Classes named *FlowChunk)
        • Classes *MemoryFlowChunk offer concrete representations that store FlowNodes in memory
      • StandardChunkVisitor: minimum ChunkVisitor implementation (assumes chunks come one after another, no nesting)
        • Extend me to store lists of chunks. 
  • Fix a NullPointerException with the FlowExecutionList
  • Dev-only: Javadocs & .gitignore changes
