Remote Differential Compression Interfaces

RDC provides the following COM interfaces that enable synchronization between two locations with an efficient use of bandwidth between the locations.

Interface	Description
IFindSimilarResults	Provides methods for retrieving information from the file list returned by the ISimilarity::FindSimilarFileId method.
IRdcComparator	Compares two signature streams (seed and source) and produces the list of seed and source file data chunks needed to create the target file.
IRdcFileReader	Provides the equivalent of a file handle, because the data being synchronized may not exist as a file on disk.
IRdcGenerator	Processes the input data and reads the parameters used by the generator.
IRdcGeneratorFilterMaxParameters	Sets and retrieves parameters used by the FilterMax generator.
IRdcGeneratorParameters	The generic interface for all types of generator parameters. All generator parameter objects must support this interface.
IRdcLibrary	The primary interface for using RDC.
IRdcSignatureReader	Reads the signatures and the parameters used to generate the signatures.
IRdcSimilarityGenerator	Defines methods for enabling the signature generator to generate similarity data and for retrieving the similarity data after it is generated.
ISimilarity	Defines methods for storing and retrieving per-file similarity data and file IDs in a similarity file.
ISimilarityFileIdTable	Defines methods for storing and retrieving similarity file ID information.
ISimilarityReportProgress	Defines a method for RDC to report the current completion percentage of a similarity operation.
ISimilarityTableDumpState	Provides a method for retrieving information from the similarity traits list that was returned by the ISimilarityTraitsTable::BeginDump method.
ISimilarityTraitsTable	Defines methods for storing per-file similarity data and performing similarity lookups.
