PipelineMonitorImageSource Class Reference

#include <itkPipelineMonitorImageFilter.h>

Detailed Description

Enables monitoring, recording and debuging of the pipeline execution and information exchange.

This filter is useful for testing, debuging, and understanding the pipeline. When DebugOn is enabled and compiled in Debug mode, many itkDebug messages are printed. This filter also features, several Verify methods which check the recorded information, for certain conditions, which should occour when well behaved filters are executed.

There are two meta verify methods that should primarily be used depending on the expected capabilities of the pipeline:

• VerifyAllInputCanStream
• VerifyAllInputCanNotStream

During the pipeline execution this filter records a variety of information to aid if verifying correct pipeline behavior:

• NumberOfUpdate the number of times GenerateData was executed
• OutputRequestedRegions an array of the output of this filter's requested region
• InputRequestedRegions an array of the input image's requested region after PropagateRequestedRegion
• UpdatedBufferedRegions an array of the input image's buffered region after upstream GenerateData
• UpdatedRequestedRegions an array of the input image's requested region after upstream GenerateData

The following are recorded from the input image after the input's output information is generated:

• UpdatedOutputOrigin
• UpdatedOutputDirection
• UpdatedOutputSpacing
• UpdatedOutputLargestPossibleRegion

This filter always runs in-place so it has no per-pixel overhead.
