Constructor Detail

MQCFST

public MQCFST()

Constructs an MQCFST instance with default field values.

MQCFST

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

Constructs an MQCFST instance populated from an MQMessage.

Parameters:

message - the message to read

Throws:

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

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

MQCFST

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

Constructs an MQCFST 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 MQCFST stucture

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

MQCFST

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

Initializes an MQCFST with the specified values.

Parameters:

parameter - the parameter identifier

string - the string parameter value

Method Detail

write

public static int write(java.io.DataOutput message,
                        int parameter,
                        java.lang.String string)
                 throws java.io.IOException

A convenience method for writing an MQCFST header structure with the specified values to an MQMessage

Parameters:

message - the message to write to

parameter - the parameter identifier

string - the string parameter value

Returns:

the number of bytes written

Throws:

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

CMQCFC

equals

public boolean equals(java.lang.Object obj)

Returns true when invoked with another MQCFST instance with the same parameter and equivalent value. Comparison of the values is performed using the equals method of String. Note: Two MQCFST instances with null values are not regarded as equal.
It doesn't really matter - such instances are not really interesting - but it's worth commenting on.

Overrides:

equals in class PCFParameter

Parameters:

obj -

Returns:

true if the object equals this one

hashCode

public int hashCode()

Description copied from class: PCFParameter

Returns a hash code value for the object

Specified by:

hashCode in class PCFParameter

Returns:

a hash code value for this object.

See Also:

PCFParameter.hashCode()

getType

public int getType()

gets the structure type

Specified by:

getType in class PCFHeader

Returns:

the structure type

getStrucLength

public int getStrucLength()

Get the length of the structure.

Returns:

the structure length.

getParameter

public int getParameter()

gets the parameter identifier

Specified by:

getParameter in class PCFParameter

Returns:

the parameter identifier

setParameter

public void setParameter(int value)

sets the parameter identifier

Parameters:

value - the parameter identifier

getCodedCharSetId

public int getCodedCharSetId()

gets the coded character set identifier

Returns:

the coded character set identifier

setCodedCharSetId

public void setCodedCharSetId(int value)

sets the coded character set identifier

Parameters:

value - the coded character set identifier

getStringLength

public int getStringLength()

gets the length of the string

Returns:

the length of the string

getString

public java.lang.String getString()

gets the string

Returns:

the string

setString

public void setString(java.lang.String value)

sets the string

Parameters:

value - the string

getValue

public java.lang.Object getValue()

Description copied from class: PCFParameter

gets the parameter value

Specified by:

getValue in class PCFParameter

Returns:

the parameter value

See Also:

PCFParameter.getValue()

getStringValue

public java.lang.String getStringValue()

Description copied from class: PCFParameter
