CheckedOutputStream

public CheckedOutputStream(OutputStream out,
                           Checksum cksum)

Creates an output stream with the specified Checksum.

参数:

out - the output stream

cksum - the checksum

方法详细资料

write

public void write(int b)
           throws IOException

Writes a byte. Will block until the byte is actually written.

覆盖:

write 在类中 FilterOutputStream

参数:

b - the byte to be written

抛出:

IOException - if an I/O error has occurred

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Writes an array of bytes. Will block until the bytes are actually written.

覆盖:

write 在类中 FilterOutputStream

参数:

b - the data to be written

off - the start offset of the data

len - the number of bytes to be written

抛出:

IOException - if an I/O error has occurred
