LengthCheckInputStream

public LengthCheckInputStream(InputStream in,
                      long expectedLength,
                      boolean includeSkipped)

Constructs an input stream that performs length check to ensure the number of bytes read from the underlying input stream is the same as the expected total.

参数:

in - the underlying input stream

expectedLength - the total length of the data in bytes expected to be read from the underlying input stream; must be non-negative.

includeSkipped - true if bytes skipped are to be considered as part of the data length; false otherwise. Typically, this parameter should be set to false for uploading data to KS3, but set to true for receiving data from KS3.

方法详细资料

read

public int read()
         throws IOException

覆盖:

read 在类中 FilterInputStream

抛出:

KS3ClientException - if the data length read has exceeded the expected total, or if the total data length is not the same as the expected total.

IOException

read

       int off,
       int len)
         throws IOException

覆盖:

read 在类中 FilterInputStream

抛出:

KS3ClientException - if the data length read has exceeded the expected total, or if the total data length is not the same as the expected total.

IOException

mark

public void mark(int readlimit)

覆盖:

mark 在类中 FilterInputStream

reset

public void reset()
           throws IOException

覆盖:

reset 在类中 FilterInputStream

抛出:

IOException

skip

public long skip(long n)
          throws IOException

覆盖:

skip 在类中 FilterInputStream

抛出:
