com.fasterxml.jackson.databind.util.TokenBuffer.asParser()
Method used to create a {@link JsonParser} that can read contentsstored in this buffer. Will use default _objectCodec for object conversions.
Note: instances are not synchronized, that is, they are not thread-safe if there are concurrent appends to the underlying buffer. @return Parser that can be used for reading contents stored in this buffer

        assertEquals("abc", str);


        // and ditto for last one
        buf = m.readValue(jp, TokenBuffer.class);
        Map<?,?> map = m.readValue(buf.asParser(), Map.class);
        assertEquals(1, map.size());
        assertEquals(Boolean.TRUE, map.get("a"));
        
        assertEquals(JsonToken.END_ARRAY, jp.nextToken());
        assertNull(jp.nextToken());
