  • Field Details

    • logger

      protected final org.slf4j.Logger logger
      The internal type, which means special processing of the input/output value.

    • metaTypeName

      private String metaTypeName
      The name of the internal META type.

    • metaType

      private SqlMetaType metaType
      The internal META type, which means special processing of the input/output value.

    • value

      private String value
