extract

public <T1,C2> void extract(Optional<T> container,
                                  ValueProcessor<T1,? super T,C2> perValueProcessor,
                                  T1 target,
                                  C2 context,
                                  ContainerExtractionContext extractionContext)

Specified by:

extract in interface ContainerExtractor<Optional<T>,T>

Type Parameters:

T1 - The type of the target of the perValueProcessor, i.e. whatever it is supposed to push the result of its processing to.

C2 - The type of the context of the perValueProcessor, i.e. whatever information it needs that is independent from the target or value.

Parameters:

container - A container to extract values from.

perValueProcessor - A processor for values extracted from the container.

target - The target to pass to the perValueProcessor.

context - The context to pass to the perValueProcessor.

extractionContext - A context for use by the container extractor itself.

multiValued

public boolean multiValued()

Specified by:

multiValued in interface ContainerExtractor<Optional<T>,T>

Returns:

true if this extractor's ContainerExtractor.extract(Object, ValueProcessor, Object, Object, ContainerExtractionContext) method may call the consumer multiple times. false if it will always call the consumer either zero or one time for a given container.
