Method Summary |
int |
available()
This method returns the number of bytes that can be read from this
stream before a read can block. |
boolean |
markSupported()
This method returns a boolean that indicates whether the mark/reset
methods are supported in this class. |
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[] b,
int off,
int len)
This method read bytes from a stream and stores them into a
caller supplied buffer. |

available
public 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 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 int read(byte[] b,
int off,
int len)
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.
markSupported
public boolean markSupported()
- Description copied from class:
java.io.InputStream
- This method returns a boolean that indicates whether the mark/reset
methods are supported in this class. Those methods can be used to
remember a specific point in the stream and reset the stream to that
point.
This method always returns false in this class, but
subclasses can override this method to return true
if they support mark/reset functionality.
