Structs

• Frame
• RangeFrameBounds
• RangeFrameOffset
  The wrapper type for ScalarImpl range frame offset, containing two expressions to help adding and subtracting the offset.
• RowsFrameBounds
• SessionFrameBounds
  To implement Session Window in a similar way to Range Frame, we define a similar frame bounds structure here. It’s very like RangeFrameBounds, but with a gap instead of start & end offset.
• SessionFrameGap
  The wrapper type for ScalarImpl session gap, containing an expression to help adding the gap to a given value.
• StateKey
  Unique and ordered identifier for a row in internal states.
• StatePos
• WindowFuncCall
• WindowStates

Enums

• FrameExclusion
