Method Details

populateInputParameter

public static <IN,
OUT> IN populateInputParameter(Processor<IN,OUT> processor,
 @Nonnull
 Values values)

Create the input object required by the processor and populate all the fields from the values object.

If Processor.createInputParameter() returns an instance of values then the values object will be returned.

Type Parameters:

IN - type of the processor input object

OUT - type of the processor output object

Parameters:

processor - the processor that the input object will be for.

values - the object containing the values to put into the input object

writeProcessorOutputToValues

public static void writeProcessorOutputToValues(Object output,
 Processor<?,?> processor,
 Values values)

Read the values from the output object and write them to the values object.

Parameters:

output - the output object from a processor

processor - the processor the output if from

values - the object for sharing values between processors

 @Nonnull
 com.google.common.collect.BiMap<String,String> inputMapper,
 @Nonnull
 String field)

Calculate the name of the input value.

Parameters:

inputPrefix - a nullable prefix to prepend to the name if non-null and non-empty

inputMapper - the name mapper

field - the field containing the value

getOutputValueName

public static String getOutputValueName(@Nullable
 String outputPrefix,
 @Nonnull
 Map<String,String> outputMapper,
 @Nonnull
 Field field)

Calculate the name of the output value.

Parameters:

outputPrefix - a nullable prefix to prepend to the name if non-null and non-empty

outputMapper - the name mapper

field - the field containing the value
