MQCFBF

public MQCFBF(MQMessage message)
       throws MQException,
              java.io.IOException

Constructs an MQCFBF instance populated from an MQMessage.

Parameters:

message - the message to read

Throws:

MQException - if the message content does not yield a valid MQCFBF stucture

java.io.IOException - if there is a problem reading the message content

MQCFBF

public MQCFBF(java.io.DataInput message,
      int encoding,
      int characterSet)
       throws MQException,
              java.io.IOException

Constructs an MQCFBF instance populated from a DataInput source.

Parameters:

message - the MQMessage or other DataInput source to read

encoding - the initial numeric encoding of the data in the message

characterSet - the initial CCSID of the data in the message

Throws:

MQException - if the message content does not yield a valid MQCFBF stucture

java.io.IOException - if there is a problem reading the message content

MQCFBF
