logReadingException

public logReadingException(java.lang.String msg,
                           java.lang.Throwable embed)

This is how you are expected to embed another exception or any other throwable in. Now if you catch all Throwables and embed them into this exception, you can guarantee the caller will get nothing but the EmbeddedException. Now the caller can just display your default message, but also can inspect if anything more serious has caused the problem.

Method Detail

setErrorCode

public void setErrorCode(int errorCodeIn)

getErrorCode

public int getErrorCode()

getCurrentPos

public long getCurrentPos()

getSequence

public int getSequence()

getAccMD

public java.security.MessageDigest getAccMD()

getAccumulatedHash

public byte[] getAccumulatedHash()

getEmbedded

public java.lang.Throwable getEmbedded()

This method returns the embedded object, if any. It can be null, if no exceptions were embedded, but if it is not null, you could figure out the cause of error more precisely.
