Usage

From source file:org.openmrs.util.OpenmrsUtil.java

/**
 * Opens input stream for given resource. This method behaves differently for different URL
 * types:/*from  www .  j a  v  a 2s  . com*/
 * <ul>
 * <li>for <b>local files</b> it returns buffered file input stream;</li>
 * <li>for <b>local JAR files</b> it reads resource content into memory buffer and returns byte
 * array input stream that wraps those buffer (this prevents locking JAR file);</li>
 * <li>for <b>common URL's</b> this method simply opens stream to that URL using standard URL
 * API.</li>
 * </ul>
 * It is not recommended to use this method for big resources within JAR files.
 * 
 * @param url resource URL
 * @return input stream for given resource
 * @throws IOException if any I/O error has occurred
