Methods

Modifier and Type	Method and Description
static void	close(Closeable... closeableArray) Tries to close the given objects and log the IOException at INFO level to make the code more readable when we assume that the IOException won't be managed.
static String	getCleanedServletPath(String fullServletPath) Used to remove trailing slash and wildcard from a servlet path. Examples : - "/foo/" becomes "/foo" - "foo/bar" becomes "/foo/bar"
static String	guestServletPath(AtmosphereConfig config)
static boolean	isAtmosphere(String className)
static boolean	isBodyBinary(AtmosphereRequest request)
static boolean	isBodyEmpty(Object o)
static Class<?>	loadClass(Class thisClass, String className)
static Object	readEntirely(AtmosphereResource r)
static byte[]	readEntirelyAsByte(AtmosphereResource r)
static StringBuilder	readEntirelyAsString(AtmosphereResource r)
static Map<String,AtmosphereFramework.MetaServiceAction>	readServiceFile(String path) This method reads the given file stored under "META-INF/services" and accessed through the framework's class loader to specify a list of actions to be done on different service classes (AtmosphereInterceptor, BroadcastFilter, etc).

Method Detail

readEntirely

public static Object readEntirely(AtmosphereResource r)

isBodyBinary

public static final boolean isBodyBinary(AtmosphereRequest request)

isBodyEmpty

public static final boolean isBodyEmpty(Object o)

readEntirelyAsString

public static StringBuilder readEntirelyAsString(AtmosphereResource r)

readEntirelyAsByte

public static byte[] readEntirelyAsByte(AtmosphereResource r)

guestServletPath

public static String guestServletPath(AtmosphereConfig config)

getCleanedServletPath

public static String getCleanedServletPath(String fullServletPath)

Used to remove trailing slash and wildcard from a servlet path.

Examples :
- "/foo/" becomes "/foo"
- "foo/bar" becomes "/foo/bar"

Parameters:

fullServletPath - : Servlet mapping

Returns:

Servlet mapping without trailing slash and wildcard

loadClass

public static Class<?> loadClass(Class thisClass,
                 String className)
                          throws Exception

Throws:

Exception

isAtmosphere

public static boolean isAtmosphere(String className)

readServiceFile

public static Map<String,AtmosphereFramework.MetaServiceAction> readServiceFile(String path)

This method reads the given file stored under "META-INF/services" and accessed through the framework's class loader to specify a list of actions to be done on different service classes (AtmosphereInterceptor, BroadcastFilter, etc).

The file content should follows the following format:

 INSTALL
 com.mycompany.MyInterceptor
 com.mycompany.MyFilter
 EXCLUDE
 org.atmosphere.interceptor.HeartbeatInterceptor
 

If you don't specify any AtmosphereFramework.MetaServiceAction before a class, then default action will be AtmosphereFramework.MetaServiceAction.INSTALL.

Important note: you must specify a class declared inside a package. Since creating classes in the source root is a bad practice, the method does not deal with it to improve its performances.

Parameters:

path - the service file to read

Returns:

the map associating class to action

close

public static void close(Closeable... closeableArray)

Tries to close the given objects and log the IOException at INFO level to make the code more readable when we assume that the IOException won't be managed.

Also ignore null parameters.

Parameters:

closeableArray - the objects to close

realPath

public static String realPath(javax.servlet.ServletContext servletContext,
              String targetPath)
                       throws MalformedURLException

Throws:

MalformedURLException
