Usage

From source file:com.github.fge.jackson.JsonNodeReader.java

private static JsonNode readNode(final MappingIterator<JsonNode> iterator) throws IOException {
    final Object source = iterator.getParser().getInputSource();
    final JsonParseExceptionBuilder builder = new JsonParseExceptionBuilder(source);

    builder.setMessage(BUNDLE.getMessage("read.noContent"));

    if (!iterator.hasNextValue())
        throw builder.build();

    final JsonNode ret = iterator.nextValue();

    builder.setMessage(BUNDLE.getMessage("read.trailingData")).setLocation(iterator.getCurrentLocation());

    try {/*from  www .  j av a2s.  c om*/
