| Method Detail |

void error(Environment environment,
String errpfx,
String msg)
When an error occurs in the Berkeley DB library, an exception is thrown. In some cases, however, the exception may be insufficient to completely describe the cause of the error, especially during initial application debugging.
The EnvironmentConfig.setErrorHandler and
DatabaseConfig.setErrorHandler methods are used to enhance
the mechanism for reporting error messages to the application. In
some cases, when an error occurs, Berkeley DB will invoke the
ErrorHandler's object error method. It is up to this method to
display the error message in an appropriate manner.
environment - The enclosing database environment handle.
errpfx - The prefix string, as previously configured by
EnvironmentConfig.setErrorPrefix or
DatabaseConfig.setErrorPrefix.
msg - An error message string.
