    Modifier and Type
    Method
    Description
    TemplateBase.CloseType
    close(Hop hop)
    Indicates if the template must be closed at the current hop; either due to final operations (e.g., aggregate) or unsupported operations.
    Pair<Hop[],CNodeTpl>
    constructCplan(Hop hop, CPlanMemoTable memo, boolean compileLiterals)
    Constructs a single cplan rooted at the given hop, according to the plan given in the memo structure for this particular hop and its recursive inputs.
    boolean
    fuse(Hop hop, Hop input)
    Indicates if the template can be expanded to the given hop starting from an open template at the input.
    boolean
    merge(Hop hop, Hop input)
    Indicates if the template at the current hop can be expanded by merging another template available for one of its other inputs which is not yet covered by the template of the current hop.
    boolean
    open(Hop hop)
    Indicates if this template can be opened at the given hop, where hop represents bottom (first operation on the inputs) of the fused operator.

    • open

      public boolean open(Hop hop)
      Description copied from class: TemplateBase
      Indicates if this template can be opened at the given hop, where hop represents bottom (first operation on the inputs) of the fused operator.
      Specified by:
      open in class TemplateBase
      Parameters:
      hop - current hop
      Returns:
      true if template can be opened

    • fuse

      public boolean fuse(Hop hop, Hop input)
      Description copied from class: TemplateBase
      Indicates if the template can be expanded to the given hop starting from an open template at the input.
      Specified by:
      fuse in class TemplateBase
      Parameters:
      hop - current hop
      input - hop with open template of same type
      Returns:
      true if the current hop can be fused into the operator.

    • merge

      public boolean merge(Hop hop, Hop input)
      Description copied from class: TemplateBase
      Indicates if the template at the current hop can be expanded by merging another template available for one of its other inputs which is not yet covered by the template of the current hop.
      Specified by:
      merge in class TemplateBase
      Parameters:
      hop - current hop
      input - direct input of current hop with available template
      Returns:
      true if the the input hop can be fused into the current hop

    • close

      public TemplateBase.CloseType close(Hop hop)
      Description copied from class: TemplateBase
      Indicates if the template must be closed at the current hop; either due to final operations (e.g., aggregate) or unsupported operations.
      Specified by:
      close in class TemplateBase
      Parameters:
      hop - current hop
      Returns:
      close type (closed invalid, closed valid, open)

    • constructCplan

      public Pair<Hop[],CNodeTpl> constructCplan(Hop hop, CPlanMemoTable memo, boolean compileLiterals)
      Description copied from class: TemplateBase
      Constructs a single cplan rooted at the given hop, according to the plan given in the memo structure for this particular hop and its recursive inputs.
      Specified by:
      constructCplan in class TemplateBase
      Parameters:
      hop - root of cplan
      memo - memoization table for partial subplans
      compileLiterals - if true compile non-integer literals as constants, otherwise variables. note: integer literals are always compiled as constants.
      Returns:
      pair containing hops and code template
