Method Detail

toByteArray

public static byte[] toByteArray(InputStream is,
                                 int length)
                          throws IOException

Throws:

IOException

copy

public static int copy(InputStream is,
                       OutputStream os,
                       WriteListener listener)
                throws IOException

Copy bytes from an InputStream to an OutputStream.

This method buffers the input internally, so there is no need to use a BufferedInputStream.

Parameters:

is - The InputStream to read from

os - The OutputStream to write to

listener - The listener for write events.

Returns:

the number of bytes copied

Throws:

NullPointerException - if the input or output is null

IOException - if an I/O error occurs

copy

public static long copy(InputStream in,
                        OutputStream out,
                        long originalByteCount)
                 throws IOException

Copies the InputStream to the specified OutputStream for the specified number of bytes or until EOF or exception.

Parameters:

in - The InputStream to copy from.

out - The OutputStream to copy to.

originalByteCount - The number of bytes to copy.

Returns:

The number of bytes written.

Throws:

IOException - If there's an IO error copying the bytes.

copy

public static long copy(InputStream is,
                        RandomAccessFile raf,
                        long offset,
                        long length)
                 throws IOException

Copy method for copying data from an InputStream to a RandomAccessFile.

Parameters:

is - The input data.

raf - The file to write to.

offset - The offset within the file to start writing at.

length - The number of bytes to copy.

Returns:

The number of bytes copied.

Throws:

IOException - If any IO error occurs.

copy

public static long copy(InputStream is,
                        RandomAccessFile raf,
                        long offset,
                        long length,
                        LongRangeListener lrl,
                        WriteListener wl)
                 throws IOException

Copy method for copying data from an InputStream to a RandomAccessFile.

Parameters:

is - The input data.

raf - The file to write to.

offset - The offset within the file to start writing at.

length - The number of bytes to copy.

Returns:

The number of bytes copied.

Throws:

IOException - If any IO error occurs.
