public interface ByteArrayWriter

Writers output raw byte arrays.

Method Summary

Modifier and Type	Method	Description
void	close()	Closes this writer and releases any associated system resources.
void	flush()	Forces writing of any buffered data.
int	readTail(byte[] data, int offset, int length)	Reads the last bytes.
void	truncate(int count)	Truncates the file size.
void	write(byte[] data, int length)	Deprecated. Replaced by write(byte[], int, int)
void	write(byte[] data, int offset, int length)	Outputs a byte array.

Method Detail

readTail

int readTail(byte[] data,
             int offset,
             int length)
      throws IOException

Reads the last bytes.

The bytes are read from the end of the current file. If the file size is equal to or greater than the passed length, the passed array is filled completely. Otherwise, the passed array is filled with the entire available file content and all remaining bytes of the array are left untouched.

Parameters:

data - Target byte array for storing the read bytes

offset - Start offset to fill passed byte array

length - Maximum number of bytes to read

Returns:

Number of read bytes

Throws:

IOException - Reading failed

write

@Deprecated
void write(byte[] data,
           int length)
    throws IOException

Deprecated. Replaced by write(byte[], int, int)

Outputs a byte array.

Parameters:

data - Byte array to output

length - Number of bytes to output

Throws:

IOException - Writing failed

write

void write(byte[] data,
           int offset,
           int length)
    throws IOException

Outputs a byte array.

Parameters:

data - Byte array to output

offset - Start offset to output

length - Number of bytes to output

Throws:

IOException - Writing failed

truncate

void truncate(int count)
       throws IOException

Truncates the file size.

Parameters:

count - Number of bytes to remove from the file end

Throws:

IOException - Resizing failed

flush

void flush()
    throws IOException

Forces writing of any buffered data.

Throws:

IOException - Writing failed

close

void close()
    throws IOException

Closes this writer and releases any associated system resources.

Throws:

IOException - Closing failed
