Field Detail

refCount

protected static final Reference refCount
Reference used to look up the equals count.

Constructor Detail

Comparator

public Comparator()
           throws java.rmi.RemoteException
Constructs Comparator object.

Throws:
java.rmi.RemoteException - if any network and RMI error
Method Detail

searchCache

public void searchCache(java.lang.Integer currentTarget)
Searches matches for a specific target.

Parameters:
currentTarget - the target

evaluate

protected int evaluate(java.lang.String from,
                       int value)
Checks if target and candidate are equal, and stop the test if they have been for 'equalsCount' times.

Overrides:
evaluate in class NetElemImpl
Parameters:
from - String identifier target or candidate
value - the integer value
Returns:
-1 if target cache is empty else evaluates value in the target cache

sfDeploy
