All Implemented Interfaces:

IBinManager

public class BinManager
extends BaseTable
implements IBinManager

This class manages the docbins table. A row in this table represents a document bin. The count that is kept is the number of documents in this particular bin that have been assigned a document priority.

getIncrementBinValues

public double[] getIncrementBinValues(java.lang.String connectorClass,
                                      java.lang.String binName,
                                      double newBinValue,
                                      int count)
                               throws ManifoldCFException

Get N bin values (and set next one). If the record does not yet exist, create it with a starting value. We expect this to happen within a transaction!!.

Specified by:

getIncrementBinValues in interface IBinManager

Parameters:

connectorClass - is the class name of the connector

binName - is the name of the bin (256 char max)

newBinValue - is the value to use if there is no such bin yet. This is the value that will be returned; what will be stored will be that value + 1.

count - is the number of values desired.

Returns:

the counter values.

Throws:

ManifoldCFException

getIncrementBinValuesInTransaction

public double[] getIncrementBinValuesInTransaction(java.lang.String connectorClass,
                                                   java.lang.String binName,
                                                   double newBinValue,
                                                   int count)
                                            throws ManifoldCFException

Get N bin values (and set next one). If the record does not yet exist, create it with a starting value. This method invokes its own retry-able transaction.

Specified by:

getIncrementBinValuesInTransaction in interface IBinManager

Parameters:

connectorClass - is the class name of the connector

binName - is the name of the bin (256 char max)

newBinValue - is the value to use if there is no such bin yet. This is the value that will be returned; what will be stored will be that value + 1.

count - is the number of values desired.

Returns:

the counter values.

Throws:

ManifoldCFException
