49.7.1CDA Exchange+ Processors

CDA Exchange+ processors require that the CDA Exchange+ (CDA_EXCHANGE_PLUS) module is running. These processors execute each individual step of the CDA Exchange+ import transformation CDA Exchange+.

Each CDA Exchange+ processor has the specifications below:

• Input: CDA Document represented as a String, or an CdaToFhirConversionResultJson
• Output: CdaToFhirConversionResultJson

A description of each CDA Exchange+ processor is provided below.

49.7.2CDA to FHIR Pre-Convert Script Processor

Executes the logic found in the pre-import script method (onPreImportCDA) that is configured in the CDA Exchange+ module. The resulting changes are set in the modifiableDocument property on the CdaToFhirConversionResultJson.

49.7.3CDA to FHIR Pre-Convert Interceptor Processor

Invokes the pointcut CDA_PRE_IMPORT, executing any interceptor code that is configured in the CDA Exchange+ module. The resulting changes are set in the modifiableDocument property on the CdaToFhirConversionResultJson.

49.7.4CDA to FHIR Conversion Processor

Translates an incoming CDA Exchange document into a FHIR transaction Bundle using the CDA Exchange+ engine. This Bundle is placed in the bundle field of the outputted CdaToFhirConversionResultJson.

49.7.5CDA to FHIR Post-Convert Script Processor

Executes the logic found in the post-import script method (onPostImportCDA) that is configured in the CDA Exchange+ module. The resulting changes to the bundle are set in the bundle property on the CdaToFhirConversionResultJson.

49.7.6CDA to FHIR Post-Convert Interceptor Processor

Invokes the pointcut CDA_POST_IMPORT, executing any interceptor code that is configured in the CDA Exchange+ module. The resulting changes to the bundle are set in the bundle property on the CdaToFhirConversionResultJson.
