构造器和说明
InputSubstream(InputStream in, long offset, long length, boolean closeSourceStream) Constructs a new InputSubstream so that when callers start reading from this stream they'll start at the specified offset in the real stream and after they've read the specified length, this stream will look empty.

InputSubstream

public InputSubstream(InputStream in,
              long offset,
              long length,
              boolean closeSourceStream)

Constructs a new InputSubstream so that when callers start reading from this stream they'll start at the specified offset in the real stream and after they've read the specified length, this stream will look empty.

参数:

in - The input stream to wrap.

offset - The offset, in bytes, into the specified input stream at which to start reading data.

length - The length, in bytes, of the specified input stream to return through this stream.

closeSourceStream - True if the wrapped InputStream should be closed when this InputSubstream is closed.
