  • Constructor Details

    • MemberTuplePredicate

      public MemberTuplePredicate(RolapCube baseCube, RolapMember lower, boolean lowerStrict, RolapMember upper, boolean upperStrict)
      Creates a MemberTuplePredicate which evaluates to true for a given range of members.

      The range can be open above or below, but at least one bound is required.

      Parameters:
      baseCube - base cube for virtual members
      lower - Member which forms the lower bound, or null if range is open below
      lowerStrict - Whether lower bound of range is strict
      upper - Member which forms the upper bound, or null if range is open above
      upperStrict - Whether upper bound of range is strict

    • MemberTuplePredicate

      public MemberTuplePredicate(RolapCube baseCube, RolapCubeMember member)
      Creates a MemberTuplePredicate which evaluates to true for a given member.
      Parameters:
      baseCube - base cube for virtual members
      member - Member

  • Method Details

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public boolean equals(Object obj)
      Overrides:
      equals in class Object

    • getConstrainedColumnList

      public List<RolapStar.Column> getConstrainedColumnList()
      Returns a list of constrained columns.
      Specified by:
      getConstrainedColumnList in interface StarPredicate
      Returns:
      List of constrained columns

    • getConstrainedColumnBitKey

      public BitKey getConstrainedColumnBitKey()
      Description copied from interface: StarPredicate
      Returns a bitmap of constrained columns to speed up comparison
      Specified by:
      getConstrainedColumnBitKey in interface StarPredicate
      Returns:
      bitmap representing all constraining columns.

    • equalConstraint

      public boolean equalConstraint(StarPredicate that)
      Description copied from interface: StarPredicate
      Returns whether this Predicate has the same constraining effect as the other constraint. This is weaker than Object.equals(Object): it is possible for two different members to constrain the same column in the same way.
      Specified by:
      equalConstraint in interface StarPredicate
      Parameters:
      that - Other predicate
      Returns:
      whether the other predicate is equivalent

    • minus

      public StarPredicate minus(StarPredicate predicate)
      Description copied from interface: StarPredicate
      Returns the logical inverse of this Predicate. The result is a Predicate which holds whenever this predicate holds but the other does not.
      Specified by:
      minus in interface StarPredicate
      Parameters:
      predicate - Predicate
      Returns:
      Combined predicate

    • or

      public StarPredicate or(StarPredicate predicate)
      Description copied from interface: StarPredicate
      Returns this union of this Predicate with another. The result is a Predicate which holds whenever either predicate holds.
      Specified by:
      or in interface StarPredicate
      Parameters:
      predicate - Predicate
      Returns:
      Combined predicate

    • and

      public StarPredicate and(StarPredicate predicate)
      Description copied from interface: StarPredicate
      Returns this intersection of this Predicate with another. The result is a Predicate which holds whenever both predicates hold.
      Specified by:
      and in interface StarPredicate
      Parameters:
      predicate - Predicate
      Returns:
      Combined predicate

    • evaluate

      public boolean evaluate(List<Object> valueList)
      Evaluates a constraint against a list of values.
      Specified by:
      evaluate in interface StarPredicate
      Parameters:
      valueList - List of values, one for each constrained column
      Returns:
      Whether constraint holds for given set of values

    • describe

      public void describe(StringBuilder buf)
      Description copied from interface: StarPredicate
      Appends a description of this predicate to a StringBuilder. For example:
      • =any
      • =5
      • in (2, 4, 6)
      Specified by:
      describe in interface StarPredicate
      Parameters:
      buf - Builder to append to

    • toSql

      public void toSql(SqlQuery sqlQuery, StringBuilder buf)
      Specified by:
      toSql in interface StarPredicate
