Class ProjectableBufferAggregator<T>

Object
AnchorBean<ChannelAggregator>
ChannelAggregator
ProjectableBufferAggregator<T>
Type Parameters:
T - buffer type used for aggregation UnsignedByteBuffer etc.
Direct Known Subclasses:
MaxProjection, MeanProjection, MinProjection, StandardDeviationProjection
public abstract class ProjectableBufferAggregator<T> extends ChannelAggregator
An aggregator that calculates the aggregation of every voxel across successive channels via a ProjectableBuffer.

This is achieved by maintaining a running sum for each voxel, and a total count of how many images were added.

      protected abstract ProjectableBuffer<T> create(VoxelDataType dataType, Extent extent) throws OperationFailedException
      Creates the ProjectableBuffer used for aggregation.
      Parameters:
      dataType - the data-type to use for the aggregated channel.
      extent - the size of the aggregated channel.
      Returns:
      a newly created ProjectableBuffer of specified type and size.
      Throws:
      OperationFailedException - if a buffer-type is unsupported.
