main

public static void main(String[] args)

indexBegin

public boolean indexBegin(Index ix,
 int height)

Description copied from class: VerificationObserver

Called before full index verification begins. Default implementation records the index and height, and then returns true.

Overrides:

indexBegin in class VerificationObserver

Parameters:

ix - index being verified

height - index height; is zero for empty indexes

Returns:

false if verification should stop

indexNodePassed

public boolean indexNodePassed(long id,
 int level,
 int entryCount,
 int freeBytes,
 int largeValueCount)

Description copied from class: VerificationObserver

Called after an index node passes verification. Implementation is free to report incremental progress or throttle verification. Default implementation does nothing but return true.

Overrides:

indexNodePassed in class VerificationObserver

Parameters:

id - ephemeral node identifier

level - index node level; root node is level one

entryCount - total number of entries in the node

freeBytes - amount of unused bytes in the node

largeValueCount - number of values which don't fit entirely in the node

Returns:

false if verification should stop

indexNodeFailed

public boolean indexNodeFailed(long id,
 int level,
 String message)

Description copied from class: VerificationObserver

Called after an index node fails verification. Implementation is free to report incremental progress or throttle verification. Default implementation prints a message to standard out and returns true.

Overrides:

indexNodeFailed in class VerificationObserver

Parameters:

id - ephemeral node identifier

level - index node level; root node is level one

message - failure message

Returns:

false if verification should stop

toString

public String toString()

Overrides:

toString in class Object
