Constructor Details

DRDAProtocolException

DRDAProtocolException(String msgid,
 DRDAConnThread agent,
 int cpArg,
 int errCdArg,
 Object[] args)

Create a new Protocol exception

Parameters:

msgid - The messageid for this message. (needs to be integrated into logging mechanism)

agent - DRDAConnThread that threw this exception

cpArg - CODPNT value to pass to send

args - Argments for the message in an Object[]

DRDAProtocolException

DRDAProtocolException(String msgid,
 DRDAConnThread agent,
 int cpArg,
 int errCdArg)

Method Details

newDisconnectException

protected static DRDAProtocolException newDisconnectException(DRDAConnThread agent,
 Object[] args)

newAgentError

protected static DRDAProtocolException newAgentError(DRDAConnThread agent,
 int svrcod,
 String rdbnam,
 String srvdgn)

isDisconnectException

protected final boolean isDisconnectException()

write

protected void write(DDMWriter writer)

write will write the Error information to the buffer. Most errors will write only the codepoint and svrcod Where appropriate the codepoint specific error code and codePoint of origin will be written

Parameters:

writer - The DDMWriter for the agent.

getMessage

public String getMessage()

Override getMessage()

Overrides:

getMessage in class Throwable

Returns:

the server diagnostic error message for this exception
