TraceInputStream

public TraceInputStream(InputStream in,
                        OutputStream traceOut)

Creates an input stream filter built on top of the specified input stream.

参数：

in - the underlying input stream.

out - the trace stream

方法详细信息

setTrace

public void setTrace(boolean trace)

Set trace mode.

参数：

trace - the trace mode

setQuote

public void setQuote(boolean quote)

Set quote mode.

参数：

quote - the quote mode

read

public int read()
         throws IOException

Reads the next byte of data from this input stream. Returns -1 if no data is available. Writes out the read byte into the trace stream, if trace mode is true

覆盖：

类 FilterInputStream 中的 read

抛出：

IOException

read

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

Reads up to len bytes of data from this input stream into an array of bytes. Returns -1 if no more data is available. Writes out the read bytes into the trace stream, if trace mode is true
