Specified by:

write in interface BeanWriter

Parameters:

recordName - the record or group name bound to the bean object from the mapping file

bean - the bean object to write

Throws:

BeanWriterException - if a record could not be identified for marshalling, or in a few other rare (but fatal) cases

flush

public void flush()
           throws BeanWriterIOException

Description copied from interface: BeanWriter

Flushes this output stream.

Specified by:

flush in interface BeanWriter

Description copied from interface: BeanWriter

Closes this output stream.

Specified by:

close in interface BeanWriter

Throws:

updateState

public void updateState(String namespace,
                        Map<String,Object> state)

Description copied from interface: StatefulWriter

Specified by:

updateState in interface StatefulWriter

Parameters:

namespace - a String to prefix all state keys with

state - the Map to update with the latest state

restoreState

public void restoreState(String namespace,
                         Map<String,Object> state)
