java.lang.Object
|
+----com.ibm.as400.access.AS400PackedDecimal
- public class AS400PackedDecimal
- extends Object
- implements AS400DataType
The AS400PackedDecimal class provides a converter between a BigDecimal object and a packed decimal format floating point number.
-
AS400PackedDecimal(int, int)
- Constructs an AS400PackedDecimal object.
-
clone()
- Creates a new AS400PackedDecimal object that is identical to the current instance.
-
getByteLength()
- Returns the byte length of the data type.
-
getDefaultValue()
- Returns a Java object representing the default value of the data type.
-
getNumberOfDecimalPositions()
- Returns the number of decimal positions in the packed decimal number.
-
getNumberOfDigits()
- Returns the total number of digits in the packed decimal number.
-
toBytes(Object)
- Converts the specified Java object to AS/400 format.
-
toBytes(Object, byte[])
- Converts the specified Java object into AS/400 format in the specified byte array.
-
toBytes(Object, byte[], int)
- Converts the specified Java object into AS/400 format in the specified byte array.
-
toObject(byte[])
- Converts the specified AS/400 data type to a Java object.
-
toObject(byte[], int)
- Converts the specified AS/400 data type to a Java object.
AS400PackedDecimal
public AS400PackedDecimal(int numDigits,
int numDecimalPositions)
- Constructs an AS400PackedDecimal object.
- Parameters:
- numDigits - The number of digits in the packed decimal number. It must be greater than or equal to one and less than or equal to thirty-one.
- numDecimalPositions - The number of decimal positions in the packed decimal number. It must be greater than or equal to zero and less than or equal to numDigits.
clone
public Object clone()
- Creates a new AS400PackedDecimal object that is identical to the current instance.
- Returns:
- The new object.
- Overrides:
- clone in class Object
getByteLength
public int getByteLength()
- Returns the byte length of the data type.
- Returns:
- The number of bytes in the AS/400 representation of the data type.
getDefaultValue
public Object getDefaultValue()
- Returns a Java object representing the default value of the data type.
- Returns:
- The BigDecimal object with a value of zero.
getNumberOfDigits
public int getNumberOfDigits()
- Returns the total number of digits in the packed decimal number.
- Returns:
- The number of digits.
getNumberOfDecimalPositions
public int getNumberOfDecimalPositions()
- Returns the number of decimal positions in the packed decimal number.
- Returns:
- The number of decimal positions.
toBytes
public byte[] toBytes(Object javaValue)
- Converts the specified Java object to AS/400 format.
- Parameters:
- javaValue - The object corresponding to the data type. It must be an instance of BigDecimal and the BigDecimal must have a less than or equal to number of digits and a less than or equal to number of decimal places.
- Returns:
- The AS/400 representation of the data type.
toBytes
public int toBytes(Object javaValue,
byte as400Value[])
- Converts the specified Java object into AS/400 format in the specified byte array.
- Parameters:
- javaValue - The object corresponding to the data type. It must be an instance of BigDecimal and the BigDecimal must have a less than or equal to number of digits and a less than or equal to number of decimal places.
- as400Value - The array to receive the data type in AS/400 format. There must be enough space to hold the AS/400 value.
- Returns:
- The number of bytes in the AS/400 representation of the data type.
toBytes
public int toBytes(Object javaValue,
byte as400Value[],
int offset)
- Converts the specified Java object into AS/400 format in the specified byte array.
- Parameters:
- javaValue - An object corresponding to the data type. It must be an instance of BigDecimal and the BigDecimal must have a less than or equal to number of digits and a less than or equal to number of decimal places.
- as400Value - The array to receive the data type in AS/400 format. There must be enough space to hold the AS/400 value.
- offset - The offset into the byte array for the start of the AS/400 value. It must be greater than or equal to zero.
- Returns:
- The number of bytes in the AS/400 representation of the data type.
toObject
public Object toObject(byte as400Value[])
- Converts the specified AS/400 data type to a Java object.
- Parameters:
- as400Value - The array containing the data type in AS/400 format. The entire data type must be represented.
- Returns:
- The BigDecimal object corresponding to the data type.
toObject
public Object toObject(byte as400Value[],
int offset)
- Converts the specified AS/400 data type to a Java object.
- Parameters:
- as400Value - The array containing the data type in AS/400 format. The entire data type must be represented and the data type must have valid packed decimal format.
- offset - The offset into the byte array for the start of the AS/400 value. It must be greater than or equal to zero.
- Returns:
- The BigDecimal object corresponding to the data type.
