ServletRequest interface

Defines an object to provide client request information to a servlet. Whenever a request came, then servlet container creates a ServletRequest object and passes it as an argument to the servlet's service method.

public interface ServletRequest {
 public Object getAttribute(String name);
 public Enumeration<String> getAttributeNames();
 public String getCharacterEncoding();
 public void setCharacterEncoding(String env) throws UnsupportedEncodingException;
 public int getContentLength();
 public long getContentLengthLong();
 public String getContentType();
 public ServletInputStream getInputStream() throws IOException;
 public String getParameter(String name);
 public Enumeration<String> getParameterNames();
 public String[] getParameterValues(String name);
 public Map<String, String[]> getParameterMap();
 public String getProtocol();
 public String getScheme();
 public String getServerName();
 public int getServerPort();
 public BufferedReader getReader() throws IOException;
 public String getRemoteAddr();
 public String getRemoteHost();
 public void setAttribute(String name, Object o);
 public void removeAttribute(String name);
 public Locale getLocale();
 public Enumeration<Locale> getLocales();
 public boolean isSecure();
 public RequestDispatcher getRequestDispatcher(String path);
 public String getRealPath(String path);
 public int getRemotePort();
 public String getLocalName();
 public String getLocalAddr();
 public int getLocalPort();
 public ServletContext getServletContext();
 public AsyncContext startAsync() throws IllegalStateException;
