      java.net.PlainSocketImpl.SocketInputStream

Enclosing class:

PlainSocketImpl

---

class PlainSocketImpl.SocketInputStream

extends java.io.InputStream

A stream which reads from the socket implementation.

Constructor Summary
(package private)	PlainSocketImpl.SocketInputStream()

 

Method Summary
int	available()           This method returns the number of bytes that can be read from this stream before a read can block.
void	close()           This method closes the stream.
int	read()           This method reads an unsigned byte from the input stream and returns it as an int in the range of 0-255.
int	read(byte[] buffer)           This method reads bytes from a stream and stores them into a caller supplied buffer.
int	read(byte[] buffer, int offset, int length)           This method read bytes from a stream and stores them into a caller supplied buffer.

Method Detail

close

public final void close()
                 throws java.io.IOException

Description copied from class: java.io.InputStream

This method closes the stream. Any futher attempts to read from the stream may generate an IOException

This method does nothing in this class, but subclasses may override this method in order to provide additional functionality.

---

available

public final int available()
                    throws java.io.IOException

Description copied from class: java.io.InputStream

This method returns the number of bytes that can be read from this stream before a read can block. A return of 0 indicates that blocking might (or might not) occur on the very next read attempt.

This method always returns 0 in this class

---

read

public final int read()
               throws java.io.IOException

Description copied from class: java.io.InputStream

This method reads an unsigned byte from the input stream and returns it as an int in the range of 0-255. This method also will return -1 if the end of the stream has been reached.

This method will block until the byte can be read.

---

read

public final int read(byte[] buffer,
                      int offset,
                      int length)
               throws java.io.IOException

Description copied from class: java.io.InputStream

This method read bytes from a stream and stores them into a caller supplied buffer. It starts storing the data at index off into the buffer and attempts to read len bytes. This method can return before reading the number of bytes requested. The actual number of bytes read is returned as an int. A -1 is returned to indicate the end of the stream.

This method will block until some data can be read.

This method operates by calling the single byte read() method in a loop until the desired number of bytes are read. The read loop stops short if the end of the stream is encountered or if an IOException is encountered on any read operation except the first. If the first attempt to read a bytes fails, the IOException is allowed to propagate upward. And subsequent IOException is caught and treated identically to an end of stream condition. Subclasses can (and should if possible) override this method to provide a more efficient implementation.

---

read

public final int read(byte[] buffer)
               throws java.io.IOException

Description copied from class: java.io.InputStream

This method reads bytes from a stream and stores them into a caller supplied buffer. This method attempts to completely fill the buffer, but can return before doing so. The actual number of bytes read is returned as an int. A -1 is returned to indicate the end of the stream.

This method will block until some data can be read.

This method operates by calling an overloaded read method like so: read(b, 0, b.length)
