Class TimestampFieldDescription

  • All Implemented Interfaces:
    Serializable


    public class TimestampFieldDescription
    extends FieldDescription
    implements Serializable
    Represents the description of the data in a Timestamp field. The TimestampFieldDescription class allows:
    • The user to describe a Timestamp field to the RecordFormat object.
    • The RecordFormat object to describe a Timestamp field to the user.

      • TimestampFieldDescription

        public TimestampFieldDescription()
        Constructs a TimestampFieldDescription object.
      • TimestampFieldDescription

        public TimestampFieldDescription(AS400Text dataType,
                                 String name)
        Constructs a TimestampFieldDescription object. It uses the data type and name of the field specified.
        Parameters:
        dataType - Describes the field and provides the conversion capability for the contents of the field.
        name - The name of the field.
      • TimestampFieldDescription

        public TimestampFieldDescription(AS400Text dataType,
                                 String name,
                                 String ddsName)
        Constructs a TimestampFieldDescription object. It uses the data type, name, and DDS name of the field specified.
        Parameters:
        dataType - Describes the field and provides the conversion capability for the contents of the field.
        name - The name of the field.
        ddsName - The DDS name of this field. This is the name of the field as it would appear in a DDS description of the field. The length of ddsName must be 10 characters or less.

    • Method Detail

      • setDataType

        public void setDataType(AS400Text dataType)
        Sets the AS400DataType object describing this field.
        Parameters:
        dataType - The AS400DataType that describes this field. The dataType cannot be null.
      • setDataType

        public void setDataType(AS400Timestamp dataType)
        Sets the AS400DataType object describing this field.
        Parameters:
        dataType - The AS400DataType that describes this field. The dataType cannot be null.
      • setDFT

        public void setDFT(String defaultValue)
        Sets the value for the DFT keyword for this field.
        Parameters:
        defaultValue - The default value for this field. The defaultValue cannot be null. To set a default value of *NULL, use the setDFTNull() method.
      • setDFTCurrent

        public void setDFTCurrent()
        Sets the default value for this field to be the current date. Calling this method will replace the DFT keyword that was previously set on a call to setDFT(String) or setDFTNull().
      • setDFTNull

        public void setDFTNull()
        Sets the value for the DFT keyword to be *NULL for this field. Calling this method will replace the DFT keyword that was previously set on a call to setDFT(String) or setDFTCurrent(). Note: This field must also have its ALWNULL keyword set to true to prevent DDS errors.
