public GlobalHolder()

Method Detail

getLambdaSolve

public static LambdaSolve getLambdaSolve()

init

public static void init()

add

public static boolean add(Object s)

putAssoc

public static void putAssoc(FeatureKey s,
                            int num)

getNum

public static int getNum(Object s)

getNum

public static int getNum(Object s,
                         HashMap fAssocs)

saveExtractors

public static void saveExtractors(String filename)
                           throws Exception

serialize the ExtractorFrames and ExtractorFramesRare in filename

Exception

saveEmissionProbabilities

public static void saveEmissionProbabilities(String filename)
                                      throws Exception

serialize the probsTable in filename

Exception

readEmissionProbabilities

public static void readEmissionProbabilities(String filename)
                                      throws Exception

read the extractors from a filename

Exception

readExtractors

public static void readExtractors(String filename)
                           throws Exception

read the extractors from a filename

Exception

save

public static void save(String filename)

save_prev

public static void save_prev(String filename)

saveAssociations

This reads the .assoc file. It is only used by LambdaSolveTagger.java The same associations also appear in the main file, and are read by read(), read_prev().

release_mem

public static void release_mem()

save_after

public static void save_after(String filename)

read

public static boolean read(String filename)

read_prev

public static void read_prev(String filename)

isRare

public static boolean isRare(String word)

main

public static void main(String[] args)
