# MultiSourceFrameImageParserBase TSourceIdentifier, TTypeIdentifier, TOutputType Class

This class defines a basic implementation of parsing functionality suitable for automating the parsing of multiple binary data streams, each represented as frames with common headers and returning the parsed data via an event.

#### Type Parameters

TSourceIdentifier
  Type of identifier for the data source.
TTypeIdentifier
  Type of identifier used to distinguish output types.
TOutputType
  Type of the interface or class used to represent outputs.

## Remarks

This parser is designed as a write-only stream such that data can come from any source.

This class is more specific than the BinaryImageParserBase in that it can automate the parsing of a particular protocol that is formatted as a series of frames that have a common method of identification. Automation of type creation occurs by loading implementations of common types that implement the ISupportSourceIdentifiableFrameImageTSourceIdentifier, TTypeIdentifier interface. The common method of identification is handled by creating a class derived from the ICommonHeaderTTypeIdentifier which primarily includes a TypeID property, but also should include any state information needed to parse a particular frame if necessary. Derived classes override the ParseCommonHeader(Byte, Int32, Int32) method in order to parse the ICommonHeaderTTypeIdentifier from a provided binary image.
