getWordInContext

public java.lang.String getWordInContext(java.lang.Integer pos,
                                java.lang.String wrd,
                                int ctx)

get a number (ctx) of characters surrounding the word (wrd) strating at position

Parameters:

wrd - the keyword

pos - a (randomly-accessible) position in this file

ctx - the number of characters before and after wrd to be returned

Returns:
