Method Detail

read

public boolean read(java.io.BufferedReader r,
                    java.util.Map<java.lang.String,InputSequence<?>> output)
             throws java.io.IOException

Description copied from interface: InterleavedInputComponent

Read the contents of the sequence in from a reader. Return false if the end of file was reached.

Parameters:

r - the buffered reader from which the next sequence should be read.

output - a map to which new components for this input sequence should be added.

Returns:

true if a sequence was read in and the map was populated. false if the end of the sequence was reached.

Throws:

java.io.IOException

write

public void write(java.io.Writer w,
                  java.util.Map<java.lang.String,? extends InputSequence<?>> data)
           throws java.io.IOException

Description copied from interface: InterleavedInputComponent

Output this sequence to the given writer.

Parameters:

w - a writer to which this sequence should be written

data - a map containing the data for the sequence to be written

Throws:

java.io.IOException

prepareData

public static java.util.List<? extends TrainingSequence<java.lang.Character>> prepareData(java.lang.String str)

Convenience function for creating training sequences in test data.
