All Implemented Interfaces:

DocumentPreProcessor

public class SplitValueDataProcessor
extends ConfigureableDataprocessor<SplitValueConfiguration>

DocumentPreProcessor implementation which splits a field value on a regular expression and adds the splitted values into new fields. Will be auto configured and can be further configuration like described below:

  data-processor-configuration: 
   processors:
     - SplitValueDataProcessor
  configuration:
    SplitValueDataProcessor:
      FieldName: ColorMapping 
      ColorMapping_keepOriginal: true
      ColorMapping_regEx: /::/
      ColorMapping_idxToDest: 0:Hauptfarbe;1:Nebenfarbe
      #Optionally a wildcard index can be supplied if the index count is not predictable when splitting a value.
      #In this case only one value is allowed and must be -1. For every splitted value a record entry 
      #in form: value_idxOfSplitted value will be added. E.g.:
      ColorMapping_idxToDest: -1:Hauptfarbe 
      # This would add Hauptfarbe_0, Hauptfarbe_1, Hauptfarbe_3 for on a value foo/::/bar/::/baz
 

This would split the value of the ColorMapping field by the regular expression /::/ assuming that it result in two splitted values. The first of the splitted values is going to be added in a new field called Hauptfarbe and the second value into a new field Nebenfarbe. Furthermore the original value of the field ColorMapping is not removed.

Method Details

getPatternConfiguration

protected SplitValueConfiguration getPatternConfiguration(String key,
 String value,
 Map<String,String> confMap)

Description copied from class: ConfigureableDataprocessor

Returns the ConfigureableField holding the parsed configuration for every configured key.

Specified by:

getPatternConfiguration in class ConfigureableDataprocessor<SplitValueConfiguration>

Parameters:

key - a key from the data processor configuration for this data processor.

value - the value of that key.

confMap - the complete data processor configuration map.

Returns:

the parsed configurable field for the key.

getProcessConsumer

protected BiConsumer<SplitValueConfiguration,Object> getProcessConsumer(Document doc,
 boolean visible)

Description copied from class: ConfigureableDataprocessor

Returns a BiConsumer whose input is the configured ConfigureableField with the value of the currently processed record. The consumer gets called in the DocumentPreProcessor.process(Document, boolean) method for each configured key.

Specified by:

getProcessConsumer in class ConfigureableDataprocessor<SplitValueConfiguration>

Parameters:

doc - the record data

visible - the current visibility of the record

Returns:

a BiConsumer whose accept method should handle every PatternConfiguration with the corresponding value.
