create

public static DataProcessor create()

Specified by:

create in interface CdsDataProcessor

action

public CdsDataProcessor action(DataProcessor.Action action)

action

public DataProcessor action(BiConsumer<CdsStructuredType,Map<String,Object>> action)

bulkAction

public DataProcessor bulkAction(BiConsumer<CdsStructuredType,Iterable<Map<String,Object>>> action)

addConverter

public DataProcessor addConverter(CdsDataProcessor.Filter filter,
                                  CdsDataProcessor.Converter valConverter)

Adds a value converter to this DataTraverser that converts values of elements that match the provided filter.

Specified by:

addConverter in interface CdsDataProcessor

Parameters:

filter - the filter predicate, see Filter

valConverter - the value converter function, see Converter

Returns:

this DataTraverser

addGenerator

public DataProcessor addGenerator(CdsDataProcessor.Filter filter,
                                  CdsDataProcessor.Generator valGenerator)

Adds a value generator for non-virtual/non-association elements matching the provided filter and either mapped to null or not mapped to any value. If the generator function returns null, the element is mapped to null.

Specified by:

addGenerator in interface CdsDataProcessor

Parameters:

filter - the filter predicate, see Filter

valGenerator - the Value Generator function

Returns:

this DataTraverser

addValidator

public DataProcessor addValidator(CdsDataProcessor.Filter filter,
                                  CdsDataProcessor.Validator validator)

Adds a validator to this DataTraverser validating values of elements that match the provided filter.

Specified by:

addValidator in interface CdsDataProcessor

Parameters:

filter - the filter predicate, see Filter

validator - the validation function, see Validator

Returns:

this DataTraverser
