Type Members

1.  case class DataSource(port: Int, result: TabularData) extends SingleTableGeneratorProgram with Product with Serializable

   An input source.

2.  case class JoinProgram(left: SingleTableGeneratorProgram, right: SingleTableGeneratorProgram, groupSize: Int, joinType: JoinType, filter: Option[Program] = None, selector: Vector[Int], result: TabularData) extends SingleTableGeneratorProgram with Product with Serializable

   A Program performing joins Note: the join operation is usually splitted into this operation and two selects which prepares the groups.

   A Program performing joins Note: the join operation is usually splitted into this operation and two selects which prepares the groups. See the Compiler.

   left

   source for the left side, usually a select which also creates grouping

   right

   source for the right side, usually a select which also creates grouping

   groupSize

   prefix size of the groups, if 0 no grouping is performed.

   joinType

   the join type. Encoding "inner", "left", "right", "outer"

   filter

   the filter applied to each possible left/right possible row.

   selector

   selected columns to return (from concatenated left and right side, including groups)

   result

   result tabular type

3.  class JoinRunner extends AnyRef
4.  sealed trait MultiTableGeneratorProgram extends TableGeneratorProgram

   Special program for generating multiple tabular output values.

5.  class MultiTableGeneratorProgramRunner extends AnyRef

   A Runner for MultiTableGeneratorProgram

6.  sealed abstract class OpCode extends AnyRef

   A Single OpCode in a stack based interpretation Machine.

7.  case class Program(args: Int, retStackDepth: Int, stackInitDepth: Int, ops: Vector[OpCode]) extends Product with Serializable

   A Program for running select statements.

   A Program for running select statements. It works using a Stack-Based mini virtual machine.

   args

   the number of arguments (can be more, but will be ignored).

   retStackDepth

   the length on the stack at the end.

   stackInitDepth

   how deep the stack should be pre-allocated. Note: argument names is part of communication protocol with a bridge.

8.  class ProgramRunner extends AnyRef

   A Trivial interpreter for Programs.

   A Trivial interpreter for Programs.

   Annotations

9.  case class SelectProgram(input: Option[SingleTableGeneratorProgram] = None, selector: Option[Program], projector: Option[Program], result: TabularData) extends SingleTableGeneratorProgram with Product with Serializable

   A compiled Select Statement.

   A compiled Select Statement.

   input

   where the data comes from (default to port 0)

   selector

   a program doing the selection. called with a row, returns bool on the stack if it succeeds. If empty, the row is always selected.

   projector

   a program doing the projection. called with a row, returns the translated row. If empty, the row is returned untouched.

10.  class SelectProgramRunner extends AnyRef

    Runs Select Programs

    Runs Select Programs

    Annotations

    @throws( ... )

11.  sealed trait SingleTableGeneratorProgram extends TableGeneratorProgram

    A Program which emits exactly one table

12.  class SingleTableGeneratorProgramRunner extends AnyRef

    Executes SingleTableGeneratorProgram programs

13.  case class SplitProgram(input: SingleTableGeneratorProgram, fractions: Vector[Double], shuffleSeed: Option[Long]) extends MultiTableGeneratorProgram with Product with Serializable

    A program for splitting input streams.

14.  sealed trait TableGeneratorProgram extends AnyRef

    A Program for genearting (temporary tables) Note: this is part of the API to the Select Bridge.

15.  case class UnionProgram(inputs: Vector[SingleTableGeneratorProgram], all: Boolean, result: TabularData, inOrder: Boolean) extends SingleTableGeneratorProgram with Product with Serializable

    A Program for performing unions.

    A Program for performing unions.

    inputs

    different inputs for the program.

    all

    if true emit all rows

    inOrder

    extension, emit result from left to right (makes it order deterministic)
