Class NExtremeArrayBufferHolder

java.lang.Object

com.jamonapi.utils.NExtremeBufferHolder

com.jamonapi.NExtremeArrayBufferHolder

All Implemented Interfaces:

BufferHolder, Serializable, Comparator

public class NExtremeArrayBufferHolder
extends NExtremeBufferHolder

Buffer used to keep the last N recent array values based on the comparator. Note the Comparator must be thread safe. It can also stored the last n recent values of ToArray objects. By using various Comparators you can determine what should stay in the buffer and what should be removed. JAMon comes with a number of buffers based on this class.

Constructor Detail

NExtremeArrayBufferHolder

public NExtremeArrayBufferHolder(JAMonArrayComparator comparator)

Constructor that takes a JAMonArrayComparator that can be used to determine when values should be removed from and added to the array. This can be used to decide what to do to values in the buffer based on multiple columns.

Parameters:

comparator -
