Method Detail

checkFunction

public TypeDetails checkFunction(Object theAppContext,
                                 String theFunctionName,
                                 List<TypeDetails> theParameters)
                          throws 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

Returns:

Throws:

PathEngineException

executeFunction

public List<Base> executeFunction(Object theAppContext,
                                  String theFunctionName,
                                  List<List<Base>> theParameters)

Specified by:

executeFunction in interface FHIRPathEngine.IEvaluationContext

Returns:

log

public boolean log(String theArgument,
                   List<Base> theFocus)

Description copied from interface: FHIRPathEngine.IEvaluationContext

when the .log() function is called

Specified by:

log in interface FHIRPathEngine.IEvaluationContext

Returns:

resolveConstant

public Base resolveConstant(Object theAppContext,
                            String theName)
                     throws 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. 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:

theAppContext - - content passed into the fluent path engine

theName - - name reference to resolve

Returns:

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

Throws:

PathEngineException

resolveConstantType

public TypeDetails resolveConstantType(Object theAppContext,
                                       String theName)
                                throws PathEngineException

Specified by:

Throws:

PathEngineException

resolveFunction

public FHIRPathEngine.IEvaluationContext.FunctionDetails resolveFunction(String theFunctionName)

Specified by:

resolveFunction in interface FHIRPathEngine.IEvaluationContext

Returns:

null if the function is not known

resolveReference

public Base resolveReference(Object theAppContext,
                             String theUrl)

Description copied from interface: FHIRPathEngine.IEvaluationContext

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

Returns:
