Class TimestampFieldDescription

java.lang.Object
  com.ibm.as400.access.FieldDescription
      com.ibm.as400.access.TimestampFieldDescription

All Implemented Interfaces:

Serializable

public class TimestampFieldDescription
extends FieldDescription
implements Serializable

The TimestampFieldDescription class 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.

Constructor Detail

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.

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.
