void |

void |
crash()
Simulates a crash of OS or machine by overwriting
unsynced files.
|
IndexOutput |
createOutput(String name,
IOContext context) |
void |
deleteFile(String name) |
boolean |
didTryToDelete(String fileName)
Returns true if
deleteFile(java.lang.String) was called with this
fileName, but the virus checker prevented the deletion. |
void |
failOn(MockDirectoryWrapper.Failure fail)
add a Failure object to the list of objects to be evaluated
at every potential failure point
|
long |
fileLength(String name) |
boolean |
getAssertNoDeleteOpenFile() |
boolean |
getEnableVirusScanner()
Returns true if the virus scanner is enabled
|
long |
getFileHandleCount()
returns current open file handle count
|

Returns the peek actual storage used (bytes) in this
directory.

double |
getRandomIOExceptionRateOnOpen() |
long |
getRecomputedActualSizeInBytes()
Like getRecomputedSizeInBytes(), but, uses actual file
lengths rather than buffer allocations (which are
quantized up to nearest
RAMOutputStream.BUFFER_SIZE (now 1024) bytes.
|
long |
getRecomputedSizeInBytes()
Provided for testing purposes.

String name) |
void |

String dest) |
void |
resetMaxUsedSizeInBytes() |
void |
setAllowRandomFileNotFoundException(boolean value)
If set to true (the default), when we throw random
IOException on openInput or createOutput, we may
sometimes throw FileNotFoundException or
NoSuchFileException.
|
void |
setAllowReadingFilesStillOpenForWrite(boolean value)
If set to true, you can open an inputstream on a file
that is still open for writes.
|
void |
setAssertLocks(boolean v)
Set to false if you want to return the pure
LockFactory and not
wrap all lock with AssertingLock . |
void |
setAssertNoDeleteOpenFile(boolean value)
Trip a test assert if there is an attempt
to delete an open file.
|
void |
setAssertNoUnrefencedFilesOnClose(boolean v) |
void |
setEnableVirusScanner(boolean value)
If set to true (the default), deleteFile sometimes
fails because a virus scanner is open.
|
void |
setFailOnCreateOutput(boolean v) |
void |
setFailOnOpenInput(boolean v) |
void |
setMaxSizeInBytes(long maxSize) |
void |
setNoDeleteOpenFile(boolean value)
Emulate windows whereby deleting an open file is not
allowed (raise IOException).
|
void |
setPreventDoubleWrite(boolean value)
If set to true, we throw an IOException if the same
file is opened by createOutput, ever.
|
void |
setRandomIOExceptionRate(double rate)
If 0.0, no exceptions will be thrown.
|
void |
setRandomIOExceptionRateOnOpen(double rate)
If 0.0, no exceptions will be thrown during openInput
and createOutput.
|
void |
setThrottling(MockDirectoryWrapper.Throttling throttling) |
void |
setTrackDiskUsage(boolean v) |
void |
setUseSlowOpenClosers(boolean v)
Add a rare small sleep to catch race conditions in open/close
|
void |
setVerboseClone(boolean v)
If set to true, we print a fake exception
with filename and stacktrace on every indexinput clone()

Be careful if you turn this off: MockDirectoryWrapper
might
no longer be able to detect if you forget to close an IndexWriter
,
and spit out horribly scary confusing exceptions instead of
simply telling you that.
