Closes the parser so that no further iteration or data access can be made; will also close the underlying input source if parser either owns the input source, or feature Feature#AUTO_CLOSE_SOURCE is enabled.

Usage

From source file:invar.lib.data.DataParserJson.java

public DataNode parse(InputStream input) throws IOException {

    JsonParser parser = factory.createParser(input);
    initParser(parser);
    parse(parser, root);
    parser.close();
    return root.numChildren() > 0 ? root.getChild(0) : root;
}
