Constructor Detail

AS400Text

public AS400Text(int length)

Constructs an AS400Text object. It uses the most likely CCSID based on the default locale.

Parameters:

length - The byte length of the IBM i text. It must be greater than or equal to zero.

AS400Text

public AS400Text(int length,
                 int ccsid)

Constructs an AS400Text object.

Parameters:

length - The byte length of the IBM i text. It must be greater than or equal to zero.

ccsid - The CCSID of the IBM i text. It must refer to a valid and available CCSID. The value 65535 will cause the data type to use the most likely CCSID based on the default locale.

public AS400Text(int length,
                 String encoding)

Constructs AS400Text object.

Parameters:

AS400Text

public AS400Text(int length,
                 AS400 system)

Constructs an AS400Text object. The CCSID used for conversion will be the CCSID of the system object.

Parameters:

length - The byte length of the IBM i text. It must be greater than or equal to zero.

system - The system with which to determine the CCSID.

AS400Text

public AS400Text(int length,
                 int ccsid,

Constructs an AS400Text object.

Parameters:

length - The byte length of the IBM i text. It must be greater than or equal to zero.

ccsid - The CCSID of the IBM i text. It must refer to a valid and available CCSID. The value 65535 will cause the data type to use the most likely CCSID based on the default locale.
