Method Detail

read

public static int read(InputStream is,
                       byte[] buffer)
                throws IOException

Attempt to read buffer.length bytes into buffer from the input steam. This implementation loops until the buffer is fully populated with data. The number of bytes actually read is returned - it may not equal buffer.length if the end of the input stream is reached.

Parameters:

is - the input stream to read from

buffer - the buffer to read into; the length of the buffer specifies the number of bytes to read

Returns:

the number of bytes actually read, can be less than buffer.length if EOF is reached

Throws:

IOException - if a read error occurs

readFully

public static void readFully(InputStream is,
                             byte[] buffer)
                      throws IOException,
                             EOFException

Attempt to read buffer.length bytes into buffer from the input steam, throw an exception if unable to read buffer.length bytes.

Parameters:

is - the input stream to read from

buffer - the buffer to read into; the length of the buffer specifies the number of bytes to read

Throws:

IOException - if a read error occurs

EOFException - if unable to read buffer.length bytes
