Examples of com.clearnlp.constituent.CTReader.nextTree()

com.clearnlp.constituent.CTReader.nextTree()
Returns the next tree, or {@code null} if there is no more tree.Returns {@code null} if the next tree is incomplete or erroneous.Automatically links antecedents of all co-indexed empty categories (see {@link CTNode#getAntecedent()}). Calls the protected method {@link CTReader#processLanguageSpecifics(CTTree)}. @return the next tree, or {@code null} if there is no more tree.

    CTReader reader = new CTReader(UTInput.createBufferedFileReader(args[0]));

    Pattern delim = Pattern.compile("\\+");

        for (String pos : delim.split(node.pTag))
          set.add(pos);
