Class ParameterConverter

java.lang.Object

org.linuxforhealth.fhir.operation.cpg.ParameterConverter

public class ParameterConverter
extends java.lang.Object

Provide conversion logic for FHIR Parameter objects both to and from the CQL System types. This relies on data type conversion logic from the FHIRTypeConverter and then is further responsible for encoding those conversions in the needed Parameter format.

Constructor Detail

ParameterConverter

public ParameterConverter(FHIRTypeConverter typeConverter)

Initialize with the given data type conversion logic.

Parameters:

typeConverter - FHIR data type conversion logic

Method Detail

toParameter

public Parameters.Parameter toParameter(java.lang.String paramName,
                                        java.util.Map<java.lang.String,java.lang.Object> expressionResults)

Convert CQL parameters into a FHIR Parameter resource

Parameters:

paramName - Name of the FHIR parameter to generate

expressionResults - CQL types to convert

Returns:

FHIR Parameter resource

toParameter

public Parameters.Parameter.Builder toParameter(java.lang.Object value)

Convert CQL value to partial FHIR parameter

Parameters:

value - CQL value

Returns:

partial FHIR parameter

toParameter

public Parameters.Parameter.Builder toParameter(Parameters.Parameter.Builder p,
                                                java.lang.Object value)

Add a CQL value to a FHIR parameter that is being built. FHIR BackboneElement types are not supported as target values and will fail. Iterable results that are lists of resources are automatically converted into FHIR bundle resources in the generated parameter. Lists of primitive values as results are not currently supported.

Parameters:

value - CQL value

Returns:

partial FHIR parameter with added value

toCql

public java.lang.Object toCql(Parameters.Parameter p)

Convert FHIR parameter contents to a CQL value

Parameters:

value - FHIR parameter

Returns:

CQL value
