Constructor Detail

MQCFBS

public MQCFBS()

Constructs an MQCFBS instance with default field values.

MQCFBS

public MQCFBS(java.io.DataInput message)
       throws MQDataException,
              java.io.IOException

Constructs an MQCFBS instance populated from an MQMessage.

Parameters:

message - the message to read

Throws:

MQDataException - if the message content does not yield a valid MQCFBS stucture

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

MQCFBS

public MQCFBS(java.io.DataInput message,
              int encoding,
              int characterSet)
       throws MQDataException,
              java.io.IOException

Constructs an MQCFBS 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:

MQDataException - if the message content does not yield a valid MQCFBS stucture

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

MQCFBS

public MQCFBS(int parameter,
              java.lang.String string)

Initializes an MQCFBS with the specified values. The string is converted into a byte array value using the platform's default string-to-bytes conversion.

Parameters:

parameter - the parameter identifier

string - the string parameter value

MQCFBS

public MQCFBS(int parameter,
              byte[] bytes)

Initializes an MQCFBS with the specified values.

Parameters:

parameter - the parameter identifier

bytes - the binary parameter value

Method Detail

equals

public boolean equals(java.lang.Object obj)

Returns true when invoked with another MQCFBS instance with the same parameter and equivalent value. Comparison of the values is performed using the java.util.Arrays.equals method.

Overrides:

equals in class PCFParameter

Parameters:

obj -

Returns:

true of the object equals this one

hashCode

public int hashCode()
