InMemory

object InMemory

In-Memory FileSystem interpreters, useful for testing/stubbing when a "real" interpreter isn't needed or desired.

NB: Since this is in-memory, careful with writing large amounts of data to the file system.

Type Members

  1. type FileMap = Map[AFile, slamdata.Predef.Vector[Data]]
  2. final case class InMemState(seq: slamdata.Predef.Long, contents: FileMap, rm: RM, wm: WM, queryResps: QueryResponses, resultMap: ResultMap) extends Product with Serializable

    Represents the current state of the InMemoryFilesystem

    Represents the current state of the InMemoryFilesystem

    seq

    Represents the next available uid for a ReadHandle or WriteHandle

    contents

    The mapping of Data associated with each file in the Filesystem

    rm

    Currently open quasar.fs.ReadFile.ReadHandles

    wm

    Currently open quasar.fs.WriteFile.WriteHandles
