Method Detail

create

public static TargetPropertyGenerator create(BeamExpressionTransform etran,
                                             ShowlDirectPropertyShape p)
                                      throws BeamTransformGenerationException

Throws:

BeamTransformGenerationException

captureValue

protected void captureValue(ShowlPropertyShape targetProperty,
                            com.helger.jcodemodel.JVar var)
                     throws BeamTransformGenerationException

Set the value of a target property in the output row, but only if the value is well-defined. The value is well-defined if it is not null and, in the case of a TableRow or List, not empty. If the target property is required and the value is not well-defined, add an error message to the ErrorBuilder.

Throws:

BeamTransformGenerationException

fail

protected void fail(String pattern,
                    Object... arguments)
             throws BeamTransformGenerationException

Throws:

BeamTransformGenerationException

generate

public BeamMethod generate(BeamMethod caller,
                           ShowlPropertyShape targetProperty)
                    throws BeamTransformGenerationException

Throws:

BeamTransformGenerationException

appendMethodNameSuffix

protected void appendMethodNameSuffix(StringBuilder builder)

returnType

protected RdfJavaType returnType(ShowlPropertyShape targetProperty)
                          throws BeamTransformGenerationException

Throws:

BeamTransformGenerationException

generateBody

protected abstract void generateBody(BeamMethod beamMethod,
                                     ShowlPropertyShape targetProperty)
                              throws BeamTransformGenerationException

Throws:
