java.lang.Objectjava.io.InputStream
javax.servlet.ServletInputStream
@TransactionType(value=NOT_SUPPORTED) public abstract class ServletInputStream
Provides an input stream for reading binary data from a client request,
including an efficient readLine method for reading data one
line at a time. With some protocols, such as HTTP POST and PUT, a
ServletInputStream object can be used to read data sent from
the client.
A ServletInputStream object is normally retrieved via the
ServletRequest.getInputStream() method.
This is an abstract class that a servlet container implements. Subclasses of
this class must implement the java.io.InputStream.read()
method.
