    • Method Detail

      • getSelectedFieldsList

        List<String> getSelectedFieldsList()
         Names of the fields in the table that should be read. If empty, all
 fields will be read. If the specified field is a nested field, all
 the sub-fields in the field will be selected. The output field order is
 unrelated to the order of fields in selected_fields.
        repeated string selected_fields = 1;
        Returns:
        A list containing the selectedFields.

      • getSelectedFieldsCount

        int getSelectedFieldsCount()
         Names of the fields in the table that should be read. If empty, all
 fields will be read. If the specified field is a nested field, all
 the sub-fields in the field will be selected. The output field order is
 unrelated to the order of fields in selected_fields.
        repeated string selected_fields = 1;
        Returns:
        The count of selectedFields.

      • getSelectedFields

        String getSelectedFields​(int index)
         Names of the fields in the table that should be read. If empty, all
 fields will be read. If the specified field is a nested field, all
 the sub-fields in the field will be selected. The output field order is
 unrelated to the order of fields in selected_fields.
        repeated string selected_fields = 1;
        Parameters:
        index - The index of the element to return.
        Returns:
        The selectedFields at the given index.

      • getSelectedFieldsBytes

        com.google.protobuf.ByteString getSelectedFieldsBytes​(int index)
         Names of the fields in the table that should be read. If empty, all
 fields will be read. If the specified field is a nested field, all
 the sub-fields in the field will be selected. The output field order is
 unrelated to the order of fields in selected_fields.
        repeated string selected_fields = 1;
        Parameters:
        index - The index of the value to return.
        Returns:
        The bytes of the selectedFields at the given index.

           "st_equals(geo_field, st_geofromtext("POINT(2, 2)"))"
           "numeric_field BETWEEN 1.0 AND 5.0"

 Restricted to a maximum length for 1 MB.
        string row_restriction = 2;
        Returns:
        The rowRestriction.
