### Question:
Synset extends PointerTarget implements DictionaryElement { @Override public void setDictionary(Dictionary dictionary) throws JWNLException { if (dictionary != this.dictionary) { if (null != this.dictionary) { Dictionary old = this.dictionary; this.dictionary = dictionary; old.removeElement(this); } super.setDictionary(dictionary); if (null != dictionary) { dictionary.addElement(this); } } } Synset(Dictionary dictionary, POS pos);  Synset(Dictionary dictionary, POS pos, long offset); DictionaryElementType getType(); Object getKey(); POS getPOS(); boolean equals(Object object); int hashCode(); String toString(); @Override Synset getSynset(); @Override int getIndex(); List<Pointer> getPointers(); String getGloss(); void setGloss(String gloss); List<Word> getWords(); long getOffset(); void setOffset(long offset); boolean isAdjectiveCluster(); void setIsAdjectiveCluster(boolean isAdjectiveCluster); String[] getVerbFrames(); BitSet getVerbFrameFlags(); void setVerbFrameFlags(BitSet verbFrameFlags); int[] getVerbFrameIndices(); boolean containsWord(String lemma); int indexOfWord(String lemma); long getLexFileNum(); void setLexFileNum(long lexFileNum); String getLexFileName(); @Override void setDictionary(Dictionary dictionary);  }### Answer:
@Test public void testSetDictionary() throws JWNLException { dictionary.edit(); mapDictionary.edit(); testObj.setDictionary(mapDictionary); List<Synset> synsets = new ArrayList<Synset>(0); Iterator<Synset> i = dictionary.getSynsetIterator(POS.NOUN); while (i.hasNext()) { synsets.add(i.next()); } Assert.assertEquals(0, synsets.size()); synsets = new ArrayList<Synset>(0); i = mapDictionary.getSynsetIterator(POS.NOUN); while (i.hasNext()) { synsets.add(i.next()); } Assert.assertEquals(1, synsets.size()); Assert.assertEquals(testObj, synsets.get(0)); }
