- 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.
Examples
-
TimestampFieldDescription()
- Constructs a TimestampFieldDescription object.
-
TimestampFieldDescription(AS400Text, String)
- Constructs a TimestampFieldDescription object.
-
TimestampFieldDescription(AS400Text, String, String)
- Constructs a TimestampFieldDescription object.
-
setDataType(AS400Text)
- Sets the AS400DataType object describing this field.
-
setDFT(String)
- Sets the value for the DFT keyword for this field.
-
setDFTCurrent()
- Sets the default value for this field to be the current date.
-
setDFTNull()
- Sets the value for the DFT keyword to be *NULL for this field.
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.
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.
