                            int ccsid,
                            AS400 system)
                     throws java.io.UnsupportedEncodingException

Constructs a LineDataRecordWriter.

Parameters:

out - An OutputStream.

ccsid - The name of the target CCSID to be used.

system - The system.

Throws:

java.io.UnsupportedEncodingException - If ccsid is not valid.

Method Detail

getCcsid

public int getCcsid()

Gets the CCSID used for this writer.

Returns:

The CCSID used for this writer.

getEncoding

public java.lang.String getEncoding()

Gets the name of the encoding being used by this LineDataRecordWriter.

Returns:

The name of the encoding being used by this LineDataRecordWriter. Null may be returned if the stream is closed.

writeRecord

public void writeRecord(Record record)
                 throws java.io.IOException,
                        java.io.UnsupportedEncodingException,
                        ExtendedIllegalStateException

Writes the record data, in line data format, to an OutputStream. The data is translated into bytes using the specified CCSID. The format of the data is determined by the record format associated with the record. The following record format attributes are required to be set.

• Record format ID
• Record format type

For a record created with record format type of VARIABLE_LAYOUT_LENGTH, the record format delimiter must be specified.
For a record created with a format type of FIXED_LAYOUT_LENGTH, the field description layout attributes, length and alignment must be specified. If alignment is not specified, alignment will be defaulted to ALIGN_LEFT.
If the OutputStream is a SpooledFileOutputStream, the SpooledFileOutputStream must have the following parameters set:

• ATTR_CONTROL_CHARACTER - Forms Control Character set to *NONE
• ATTR_CONVERT_LINE_DATA - Convert Line Data set to *YES
• ATTR_FORM_DEFINITION - Form definition integrated file system name
• ATTR_PAGE_DEFINITION - Page definition integrated file system name
• ATTR_PRTDEVTYPE - Printer device type set to *LINE

Parameters:

record - The record to be converted to line data.

Throws:

java.io.IOException - If an error occurs while communicating with the AS/400.

java.io.UnsupportedEncodingException - If in not valid.
