Method Detail

read

public boolean read()
             throws MonitoringLogReaderException

Description copied from interface: IMonitoringLogReader

Starts the reader. This method is intended to be a blocking operation, i.e., it is assumed that reading has finished before this method returns.

Returns:

true iff reading was successful

Throws:

MonitoringLogReaderException

init

public void init(String initString)
          throws IllegalArgumentException

Description copied from interface: IMonitoringLogReader

Initialize instance from passed initialization string which is typically a list of separated parameter/values pairs. The implementing class AbstractMonitoringLogWriter includes convenient methods to extract configuration values from an initString. TODO: make signature of this init method and the writer's init method (returns boolean and doesn't throw exception) consistent.

Parameters:

initString - List of input directories separated by semicolon

Throws:

IllegalArgumentException - if an error occured
