Class BlotterItem

java.lang.Object
com.caplin.datasource.blotter.BlotterItem
public class BlotterItem extends Object

BlotterItem is the data type representing a single item on the blotter. It is identified by the uniqueId passed into the constructor. It provides methods for setting its fields.

BlotterItems are passed into the BlotterChannel.sendBlotterItem(BlotterItem) and BlotterChannel.sendBlotterItems(java.util.List) methods on the BlotterChannel received on BlotterApplicationListener callbacks.

The uniqueId replaces the '%i' in the itemNamespace passed into the BlotterConfiguration to create the record subject for this item.

BlotterItems can be reused in different BlotterChannels as they are completely separate from them.
