                long time)
```
    Constructor
    
    Parameters:
    
    myTimeoutLock - The Latch that the timeout happened on
    
    myLockTable -
    
    time - The time when the lockTable was cloned.
- Method Detail
  - createException
```
private StandardException createException()
```
    createException creates a StandardException based on: currentLock a snapshot of the lockTable
    
    Returns:
    
    StandardException The exception with the lockTable snapshot in it

```
private java.lang.String buildLockTableString()
                                       throws StandardException
```
    buildLockTableString creates a LockTable info String
    
    Throws:
    
    StandardException
  - buildException
```
static StandardException buildException(Latch timeoutLock,
                                        java.util.Enumeration table,
                                        long time)
```
    The static entry way to get the LockTable in the system.
    
    Parameters:
    
    timeoutLock - The Latch that the timeout happened on
    
    table - The lockTable
    
    time - The time when the lockTable was cloned
    
    Returns:
    
    StandardException The exception with the lockTable snapshot in it
  - buildString
```
public static java.lang.String buildString(java.util.Enumeration table,
                                           long time)
                                    throws StandardException
```
    Throws:
    
    StandardException
  - dumpLock
```
private void dumpLock()
               throws StandardException
```
    dumpLock puts information about currentLock into currentRow for output later.
    
    Throws:
    
    StandardException
  - cpArray
```
private void cpArray(java.lang.String toCp,
                     int start,
                     int end)
```
    cpArray helps built the output string (outputRow).
    
    Parameters:
    
    toCp - the String to be copied into outputRow
    
    start - the start place
    
    end - the end place
  - timeoutInfoHash
```
private boolean timeoutInfoHash()
```
    Copies the needed information from currentRow into the StringBuffer for output
    
    Returns:
    
    true if successful
