the class CrossProtocolTranslator method getCoapOptions.

/**
 * Gets the coap options starting from an array of http headers.
 *
 * The content-type is not handled by this method. The method iterates over
 * an array of headers and for each of them tries to find a mapping in the
 * properties file, if the mapping does not exists it skips the header
 * ignoring it. The method handles separately certain headers which are
 * translated to options (such as accept or cache-control) whose content
 * should be semantically checked or requires ad-hoc translation. Otherwise,
 * the headers content is translated with the appropriate format required by
 * the mapped option.
 *
 * @param headers array of http headers
 * @param etagTranslator translator for etag
 * @return list of CoAP options.
 * @throws NullPointerException if headers is {@code null}
