public class PackedDecimalFieldDescription
extends FieldDescription
implements Serializable
The PackedDecimalFieldDescription class represents the description of the data in a packed decimal field. It allows: Examples


Constructor Index

 o PackedDecimalFieldDescription()
Constructs a PackedDecimalFieldDescription object.
 o PackedDecimalFieldDescription(AS400PackedDecimal, String)
Constructs a PackedDecimalFieldDescription object.
 o PackedDecimalFieldDescription(AS400PackedDecimal, String, String)
Constructs a PackedDecimalFieldDescription object.

Method Index

 o getDecimalPositions()
Returns the number of digits after the decimal point for this field.
 o setDataType(AS400PackedDecimal)
Sets the AS400DataType object describing this field.
 o setDFT(BigDecimal)
Sets the value for the DFT keyword for this field.
 o setDFTNull()
Sets the value for the DFT keyword to be *NULL for this field.

Constructors

 o PackedDecimalFieldDescription
 public PackedDecimalFieldDescription(AS400PackedDecimal dataType,
                                      String name)
Constructs a PackedDecimalFieldDescription object. It uses the specified data type and name of the field. The number of digits and the number of decimal positions will be determined from dataType.

Parameters:
dataType - Describes the field and provides the conversion capability for the contents of the field.
name - The name of the field.
 o PackedDecimalFieldDescription
 public PackedDecimalFieldDescription()
Constructs a PackedDecimalFieldDescription object.

 o PackedDecimalFieldDescription
 public PackedDecimalFieldDescription(AS400PackedDecimal dataType,
                                      String name,
                                      String ddsName)
Constructs a PackedDecimalFieldDescription object. It uses the specified data type, name, and DDS name of the field. The number of digits and the number of decimal positions will be determined from dataType.

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.

Methods

 o getDecimalPositions
 public int getDecimalPositions()
Returns the number of digits after the decimal point for this field.

Returns:
The number of digits after the decimal point.
 o setDataType
 public void setDataType(AS400PackedDecimal dataType)
Sets the AS400DataType object describing this field.

Parameters:
dataType - The AS400DataType that describes this field. The dataType cannot be null.
 o setDFT
 public void setDFT(BigDecimal 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.
 o 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(). Note: This field must also have its ALWNULL keyword set to true to prevent DDS errors.
