resolveConstant

public List<Base> resolveConstant(FHIRPathEngine engine,
 Object appContext,
 String name,
 boolean beforeContext,
 boolean explicitConstant)
                           throws org.hl7.fhir.exceptions.PathEngineException

Description copied from interface: FHIRPathEngine.IEvaluationContext

A constant reference - e.g. a reference to a name that must be resolved in context. The % will be removed from the constant name before this is invoked. Variables created with defineVariable will not be processed by resolveConstant (or resolveConstantType) This will also be called if the host invokes the FluentPath engine with a context of null

Specified by:

resolveConstant in interface FHIRPathEngine.IEvaluationContext

Parameters:

appContext - - content passed into the fluent path engine

name - - name reference to resolve

beforeContext - - whether this is being called before the name is resolved locally, or not

Returns:

the value of the reference (or null, if it's not valid, though can throw an exception if desired)

Throws:

org.hl7.fhir.exceptions.PathEngineException

resolveConstantType

public TypeDetails resolveConstantType(FHIRPathEngine engine,
 Object appContext,
 String name,
 boolean explicitConstant)
                                throws org.hl7.fhir.exceptions.PathEngineException

Specified by:

resolveConstantType in interface FHIRPathEngine.IEvaluationContext

Throws:

org.hl7.fhir.exceptions.PathEngineException

paramIsType

public boolean paramIsType(String name,
 int index)

Description copied from interface: FHIRPathEngine.IEvaluationContext

For the moment, there can only be one parameter if it's a type parameter

Specified by:

paramIsType in interface FHIRPathEngine.IEvaluationContext

Parameters:

name -

Returns:

true if it's a type parameter

log

public boolean log(String argument,
 List<Base> focus)

Description copied from interface: FHIRPathEngine.IEvaluationContext

when the .log() function is called

Specified by:

log in interface FHIRPathEngine.IEvaluationContext

Parameters:

argument -

focus -

Returns:

resolveFunction

public FHIRPathUtilityClasses.FunctionDetails resolveFunction(FHIRPathEngine engine,
 String functionName)

Specified by:

resolveFunction in interface FHIRPathEngine.IEvaluationContext

Parameters:

functionName -

Returns:

null if the function is not known

checkFunction

public TypeDetails checkFunction(FHIRPathEngine engine,
 Object appContext,
 String functionName,
 TypeDetails focus,
 List<TypeDetails> parameters)
                          throws org.hl7.fhir.exceptions.PathEngineException

Description copied from interface: FHIRPathEngine.IEvaluationContext

Check the function parameters, and throw an error if they are incorrect, or return the type for the function

Specified by:

checkFunction in interface FHIRPathEngine.IEvaluationContext

Parameters:

functionName -

parameters -

Returns:

Throws:

org.hl7.fhir.exceptions.PathEngineException

executeFunction

public List<Base> executeFunction(FHIRPathEngine engine,
 Object appContext,
 List<Base> focus,
 String functionName,
 List<List<Base>> parameters)

Specified by:

executeFunction in interface FHIRPathEngine.IEvaluationContext

Parameters:

appContext -

functionName -

parameters -

Returns:

resolveReference

public Base resolveReference(FHIRPathEngine engine,
 Object appContext,
 String url,
 Base refContext)

Description copied from interface: FHIRPathEngine.IEvaluationContext

Implementation of resolve() function. Passed a string, return matching resource, if one is known - else null

Specified by:

resolveReference in interface FHIRPathEngine.IEvaluationContext

Parameters:

url - the reference (Reference.reference or the value of the canonical

Returns:

conformsToProfile

public boolean conformsToProfile(FHIRPathEngine engine,
 Object appContext,
