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.

Specified by:

read in interface InterleavedInputComponent

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

readSequence

public int[] readSequence(java.io.BufferedReader r)
                   throws java.io.IOException

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.

Specified by:

write in interface InterleavedInputComponent

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

writeSequence

public void writeSequence(java.io.Writer w,
                          int[] data)
                   throws java.io.IOException

Throws:

java.io.IOException

readTrainingSequences

public void readTrainingSequences(java.lang.Object location,
                                  java.util.List<TrainingSequence<java.util.Map<java.lang.String,java.lang.Object>>> seqs)
                           throws java.io.IOException

Description copied from interface: TrainingSequenceIO

reads training sequences from the specified location.

Specified by:

readTrainingSequences in interface TrainingSequenceIO

Parameters:

location - location of the training sequences. Meaning is implementation dependent.

seqs - a list of the input sequences to which hidden sequences should be added. Each hidden sequence is an array of integers containing hidden state indices.

Throws:

java.io.IOException

writeTrainingSequences

public void writeTrainingSequences(java.lang.Object location,
                                   java.util.Iterator<int[]> data)
                            throws java.io.IOException

Description copied from interface: TrainingSequenceIO

writes training sequences to the specified location.

Specified by:

writeTrainingSequences in interface TrainingSequenceIO

Parameters:

location - location of the training sequences. Meaning is implementation dependent.

data - iterator over the hidden states to write.

Throws:

java.io.IOException

prepareData

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

Convenience function for creating training sequences in test data.

Throws:

java.lang.Exception
