Constructor Detail

UnreliableFilterInputStream

public UnreliableFilterInputStream(InputStream in,
                           boolean isFakeIOException)

Method Detail

read

public int read()
         throws IOException

Overrides:

read in class FilterInputStream

Throws:

IOException

read

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

Overrides:

read in class FilterInputStream

Throws:

IOException

mark

public void mark(int readlimit)

Overrides:

mark in class FilterInputStream

reset

public void reset()
           throws IOException

Overrides:

reset in class FilterInputStream

Throws:

IOException

getCurrNumErrors

public int getCurrNumErrors()

getMaxNumErrors

public int getMaxNumErrors()

withMaxNumErrors

public UnreliableFilterInputStream withMaxNumErrors(int maxNumErrors)

withBytesReadBeforeException

public UnreliableFilterInputStream withBytesReadBeforeException(int bytesReadBeforeException)

getBytesReadBeforeException

public int getBytesReadBeforeException()

withResetIntervalBeforeException

public UnreliableFilterInputStream withResetIntervalBeforeException(int resetIntervalBeforeException)

Parameters:

resetIntervalBeforeException - used to control whether an exception would be thrown based on the reset recurrence; not applicable if set to zero. For example, if resetIntervalBeforeException == n, the exception can only be thrown before the n_th reset (or after the n_th minus 1 reset), 2n_th reset (or after the 2n_th minus 1) reset), etc.

getResetIntervalBeforeException

getMarked

public int getMarked()

getPosition

public int getPosition()

isFakeIOException

public boolean isFakeIOException()

getResetCount

public int getResetCount()

toString

public String toString()

Overrides:

toString in class Object
