    - #### bindIndex

          protected final int bindIndex

    - #### receiver

          protected final ColumnSpecification receiver

  - ### Constructor Detail

    - #### AbstractMarker

          protected AbstractMarker(int bindIndex,
                        ColumnSpecification receiver)

  - ### Method Detail

    - #### collectMarkerSpecification

          public void collectMarkerSpecification(VariableSpecifications boundNames)

      Description copied from interface: `Term`
      Collects the column specification for the bind variables in this Term. This is obviously a no-op if the term is Terminal.
      Parameters:
        `boundNames` - the variables specification where to collect the bind variables of this term in.

    - #### containsBindMarker

          public boolean containsBindMarker()

      Description copied from interface: `Term`
      Whether or not that term contains at least one bind marker. Note that this is slightly different from being or not a NonTerminal, because calls to non pure functions will be NonTerminal (see #5616) even if they don't have bind markers.
