Class FilteredBlock

  • public class FilteredBlock
    extends Message

    A FilteredBlock is used to relay a block with its transactions filtered using a BloomFilter. It consists of the block header and a PartialMerkleTree which contains the transactions which matched the filter.

    Instances of this class are not safe for use by multiple threads.
