 Constructor.
 _PEAR ()
 Destructor (the emulated type of...).
& getStaticProperty ($class, $var)
 If you have a class that's mostly/entirely static, and you need static properties, you can use this method to simulate them.
 registerShutdownFunc ($func, $args=array())
 Use this function to register a shutdown method for static classes.
 isError ($data, $code=null)
 Tell whether a value is a PEAR error.
 setErrorHandling ($mode=null, $options=null)

 This method is used to tell which errors you expect to get.
 popExpect ()
 This method pops one element off the expected error codes stack.
 _checkDelExpect ($error_code)
 This method checks unsets an error code if available.
