Interface ComparisonExpression

    • Method Detail

      • getAtomicComparer

        AtomicComparer getAtomicComparer()
        Get the AtomicComparer used to compare atomic values. This encapsulates any collation that is used
        Returns:
        the comparer
      • getStringCollator

        StringCollator getStringCollator()
        Get the StringCollator used to compare string values.
        Returns:
        the collator. May return null if the expression will never be used to compare strings
      • getSingletonOperator

        int getSingletonOperator()
        Get the primitive (singleton) operator used: one of Token.FEQ, Token.FNE, Token.FLT, Token.FGT, Token.FLE, Token.FGE
        Returns:
        the operator, as defined in class Token
      • getLhs

        Operand getLhs()
        Get the left-hand operand of the comparison
        Returns:
        the first operand
      • getRhs

        Operand getRhs()
        Get the right-hand operand of the comparison
        Returns:
        the second operand
      • getLhsExpression

        Expression getLhsExpression()
        Get the left-hand expression
        Returns:
        the first operand expression
      • getRhsExpression

        Expression getRhsExpression()
        Get the right-hand expression
        Returns:
        the second operand expression
      • convertsUntypedToOther

        boolean convertsUntypedToOther()
        Determine whether untyped atomic values should be converted to the type of the other operand
        Returns:
        true if untyped values should be converted to the type of the other operand, false if they should be converted to strings.
