getReverseMap

public Map<String,Set<String>> getReverseMap()

return a reversed map of the current map

addMap

public void addMap(Map<String,Set<String>> addM)

Add all of the mappings from the specified map to the current map.

toString

public String toString()

Overrides:

toString in class Object

size

public int size()

main

public static void main(String[] args)
                 throws IOException

The main method reads (segmented, whitespace delimited) words from a file and prints them with their English translation(s). The path and filename of the CEDict Lexicon can be supplied via the "-dictPath" flag; otherwise the default filename "cedict_ts.u8" in the current directory is checked. By default, only the first translation is printed. If the "-all" flag is given, all translations are printed. The input and output encoding can be specified using the "-encoding" flag. Otherwise UTF-8 is assumed.

Throws:

IOException
