Class LoggerInputStream

java.lang.Object

java.io.InputStream

jdeserialize.LoggerInputStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class LoggerInputStream
extends java.io.InputStream

An InputStream designed to record data passing through the stream after a call to record() is made. After record() is called, the results from every read will be stored in an * internal buffer. The contents of the buffer can be retrieved by getRecordedData(); to stop recording and clear the internal buffer, call stopRecording().

Note: calls to mark() and reset() are merely passed through to the inner stream; if recording is active, the buffer won't be backtracked by reset().

         throws java.io.IOException

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException

read

public int read(byte[] b)
         throws java.io.IOException

Overrides:

read in class java.io.InputStream

Throws:

java.io.IOException

read

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

Overrides:

read in class java.io.InputStream

Throws:

java.io.IOException

skip

public long skip(long n)
          throws java.io.IOException

Overrides:

skip in class java.io.InputStream

Throws:

java.io.IOException

available

public int available()
              throws java.io.IOException

Overrides:

available in class java.io.InputStream

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.InputStream

Throws:

java.io.IOException

mark

public void mark(int readlimit)

Overrides:

mark in class java.io.InputStream

reset

public void reset()
           throws java.io.IOException

Overrides:

reset in class java.io.InputStream

Throws:

java.io.IOException

markSupported

public boolean markSupported()

Overrides:

markSupported in class java.io.InputStream

record

public void record()

If not currently recording, start recording. If the stream is currently recording, the current buffer is cleared.

stopRecording

public void stopRecording()
                   throws java.io.IOException

Stops recording and clears the internal buffer. If recording is not active, an IOException is thrown.

Throws:

java.io.IOException - if recording is not currently active

getRecordedData

public byte[] getRecordedData()

Returns the data recorded so far; if recording is not active, an empty buffer is returned.
