Master Index Block Picker Plug-ins

The block picker chooses which block definition in the blocking query to use for the next matching pass. You can create a custom block picker class to select query blocks in a customized manner. If you create a custom block picker, specify the fully qualified name of this custom plug-in for the block-picker element of mefa.xml. Follow these guidelines when implementing a custom block picker.

• Implement the com.sun.mdm.index.matching.BlockPicker interface to select the blocks in the desired order.

• If none of the remaining blocks should be executed, throw a NoBlockApplicableException from the pickBlock method.
