Constructor Detail

StringDictionary

public StringDictionary(java.lang.String name)

Method Detail

setMode

public void setMode(boolean mode)

size

public int size()

get

public int get(java.lang.String s)

getIndexAndCount

public StringDictionary.IndexAndCount getIndexAndCount(java.lang.String s)

get

public int get(java.lang.String s,
               boolean shouldThrow)

Fetches the index of this string If mCreate is true, the entry is created if it does not exist. If mCreate is true, the count of the entry is incremented for every get If no entry found throws an exception if shouldThrow == true

get

public java.lang.String get(int idx)

Reverse mapping from integer key to string value

getCount

public int getCount(int idx)

save

public void save(java.lang.String path,
                 java.lang.String prefix,
                 int threshold)
          throws java.io.IOException

Saves all dictionary entries that appeared > threshold times Note: feature indices are changed to contiguous values starting at 0. This is needed in order to minimize the memory allocated for the expanded feature vectors (average perceptron).

Throws:

java.io.IOException

clear

public void clear()

keySet

public java.util.Set<java.lang.String> keySet()

load

public void load(java.lang.String path,
                 java.lang.String prefix)
          throws java.io.IOException

Loads all saved dictionary entries from disk

Throws:

java.io.IOException

keys

public java.util.Set<java.lang.String> keys()
