  • Method Details

    • isSlice

      default boolean isSlice()

    • isEQ

      default boolean isEQ()

    • isLIKE

      default boolean isLIKE()

    • isIN

      default boolean isIN()

    • isContains

      default boolean isContains()

    • isANN

      default boolean isANN()

    • isEqualityBased

      default boolean isEqualityBased()
      Returns:
      true if this restriction is based on equality comparison rather than a range or negation

    • isNotNull

      default boolean isNotNull()

    • isMultiColumn

      default boolean isMultiColumn()

    • hasBound

      default boolean hasBound(Bound b)
      Checks if the specified bound is set or not.
      Parameters:
      b - the bound type
      Returns:
      true if the specified bound is set, false otherwise

    • isInclusive

      default boolean isInclusive(Bound b)
      Checks if the specified bound is inclusive or not.
      Parameters:
      b - the bound type
      Returns:
      true if the specified bound is inclusive, false otherwise

    • mergeWith

      SingleRestriction mergeWith(SingleRestriction otherRestriction)
      Merges this restriction with the specified one.

      Restriction are immutable. Therefore merging two restrictions result in a new one. The reason behind this choice is that it allow a great flexibility in the way the merging can done while preventing any side effect.

      Parameters:
      otherRestriction - the restriction to merge into this one
      Returns:
      the restriction resulting of the merge

    • appendTo

      MultiCBuilder appendTo(MultiCBuilder builder, QueryOptions options)
      Appends the values of this SingleRestriction to the specified builder.
      Parameters:
      builder - the MultiCBuilder to append to.
      options - the query options
      Returns:
      the MultiCBuilder

    • appendBoundTo

      default MultiCBuilder appendBoundTo(MultiCBuilder builder, Bound bound, QueryOptions options)
      Appends the values of the SingleRestriction for the specified bound to the specified builder.
      Parameters:
      builder - the MultiCBuilder to append to.
      bound - the bound
      options - the query options
      Returns:
      the MultiCBuilder
