  calhoun.analysis.crf.io.OutputHandlerComposite

All Implemented Interfaces:

OutputHandler, java.io.Serializable

public class OutputHandlerComposite
extends java.lang.Object
implements OutputHandler

an output handler that allows multiple output handlers to be configured. Each result is handed to each output handler in the list.

OutputHandlerComposite

public OutputHandlerComposite()

Method Detail

setOutputLocation

public void setOutputLocation(java.lang.String location)

Description copied from interface: OutputHandler

sets the output location to write to. This is called before any of the write functions are called.

Specified by:

setOutputLocation in interface OutputHandler

Parameters:

location - the location to write the data to. The meaning is implementation dependent.

writeOutput

public void writeOutput(InputSequence<?> sequence,
                        int[] hiddenStates)
                 throws java.io.IOException

Description copied from interface: OutputHandler

Writes out a set of predicted hidden states. The location will have been specified previously with OutputHandler.setOutputLocation(java.lang.String)

Specified by:

writeOutput in interface OutputHandler

Parameters:

sequence - the input sequence on which predictions were made

hiddenStates - an array of state indices for the predicted hidden states.

Throws:

java.io.IOException

writeTestOutput

public void writeTestOutput(InputSequence<?> sequence,
                            int[] truePath,
                            int[] hiddenStates)
                     throws java.io.IOException

Description copied from interface: OutputHandler

Writes out a set of hidden states compared with a known true path. The location will have been specified previously with OutputHandler.setOutputLocation(java.lang.String)

Specified by:

writeTestOutput in interface OutputHandler

Parameters:

sequence - the input sequence on which predictions were made

truePath - an array of hidden states representing the true path.

hiddenStates - an array of state indices for the predicted hidden states.

Throws:

java.io.IOException

outputComplete

public void outputComplete()
                    throws java.io.IOException

Description copied from interface: OutputHandler

indicates the writing of output is complete. The handler can do any final processing and release resources.

Specified by:

outputComplete in interface OutputHandler

Throws:

java.io.IOException

getHandlers

public java.util.List<OutputHandler> getHandlers()

retursn the configured list of output handler.

Returns:

returns the output handlers

setHandlers

public void setHandlers(java.util.List<OutputHandler> handlers)

sets the list of output handlers

Parameters:

handlers - a list of output handlers. The output handlers will be called in order for each prediction or test result.
