    • Method Detail

      • toFilter

        public static Filter toFilter​(String cql2Predicate)
                               throws CQLException
        Parses the input string in CQL2 format into a Filter, using the systems default FilterFactory implementation.
        Parameters:
        cql2Predicate - a string containing a query predicate in CQL format.
        Returns:
        a Filter equivalent to the constraint specified in CQL2 .
        Throws:
        CQLException
      • toFilter

        public static Filter toFilter​(String cql2Predicate,
                                      FilterFactory filterFactory)
                               throws CQLException
        Parses the input string in CQL2 format into a Filter, using the provided FilterFactory.
        Parameters:
        cql2Predicate - a string containing a query predicate in CQL2 format.
        filterFactory - the FilterFactory to use for the creation of the Filter. If it is null the method finds the default implementation.
        Returns:
        a Filter equivalent to the constraint specified in Predicate.
        Throws:
        CQLException
      • toExpression

        public static Expression toExpression​(String cql2Expression)
                                       throws CQLException
        Parses the input string in CQL2 format into an Expression, using the systems default FilterFactory implementation.
        Parameters:
        cql2Expression - a string containing an CQL2 expression.
        Returns:
        a Expression equivalent to the one specified in cql2Expression.
        Throws:
        CQLException
      • toExpression

        public static Expression toExpression​(String cql2Expression,
                                              FilterFactory filterFactory)
                                       throws CQLException
        Parses the input string in CQL2 format and makes the correspondent Expression , using the provided FilterFactory.
        Parameters:
        cql2Expression - a string containing a CQL2 expression.
        filterFactory - the FilterFactory to use for the creation of the Expression. If it is null the method finds the default implementation.
        Returns:
        a Filter equivalent to the constraint specified in cql2Expression .
        Throws:
        CQLException
      • toCQL2

        public static String toCQL2​(Filter filter)
        Generates the CQL2 predicate associated to the Filter object.
        Returns:
        CQL2 predicate
      • toCQL2

        public static String toCQL2​(Expression expression)
        Generates the expression text associated to the Expression object.
        Returns:
        expression as text
