    • visit

      public final Void visit(Constant<?> expr, Void context)
      Description copied from interface: Visitor
      Visit a Constant instance with the given context
      Specified by:
      visit in interface Visitor<Void,Void>
      Parameters:
      expr - expression to visit
      context - context of the visit or null, if not used
      Returns:
      visit result

    • visitConstant

    • serializeConstant

      protected void serializeConstant(int parameterIndex, String constantLabel)
      Serialize the constant as parameter to the query. The default implementation writes the label name for the constants. Some dialects may replace this by indexed based or positional parameterization. Dialects may also use this to prefix the parameter with for example ":" or "?".
      Parameters:
      parameterIndex - index at which this constant occurs in getConstants()
      constantLabel - label under which this constant occurs in getConstantToLabel()

    • getConstantLabel

      @NotNull protected @NotNull String getConstantLabel(Object value)
      Generate a constant value under which to register a new constant in getConstantToLabel().
      Parameters:
      value - the constant value or parameter to create a constant for
      Returns:
      the generated label

    • getConstants

      visit in interface Visitor<Void,Void>
      Parameters:
      param - expression to visit
      context - context of the visit or null, if not used
