All Implemented Interfaces:

CSVReader<T>, CSVWriter<T>

public class AdvancedCsvProcessor<T>
extends ReflectionCSVProcessor<T>

Extension of the ReflectionCSVProcessor. It is advanced as it takes an AdvancedCsvProcessorConfig in order to configure the normalisation of the column headers to allow improved mapping of csv files to objects

Since:

2.0

Constructor Detail

AdvancedCsvProcessor

public AdvancedCsvProcessor(char separator,
                            List<String> columnDefinition,
                            Class<T> clazz,
                            AdvancedCsvProcessorConfig csvProcessorConfig)

Constructor of a AdvancedCsvProcessor for domain types with simple-typed properties only (int, double, float, long, boolean, char, Integer, Float, Double, Long, String, Character, Boolean)

Parameters:

separator - separator used in the csv file

columnDefinition - columnDefinition of the csv file (can be null for reading if the CSV file contains a header which is used in CSVProcessor.read(File, boolean, boolean))

clazz - clazz of domain type

csvProcessorConfig - Configuration for this class. Defines how the header normalization should be handled

AdvancedCsvProcessor

public AdvancedCsvProcessor(char separator,
                            List<String> columnDefinition,
                            Class<T> clazz)

Constructor of a AdvancedCsvProcessor for domain types with simple-typed properties only (int, double, float, long, boolean, char, Integer, Float, Double, Long, String, Character, Boolean). The configuration is set to a default, meaning only whitespaces of the column headers are trimmed and concatenated into one "word"

Parameters:

separator - separator used in the csv file

columnDefinition - columnDefinition of the csv file (can be null for reading if the CSV file contains a header which is used in CSVProcessor.read(File, boolean, boolean))

clazz - clazz of domain type

Method Detail

normalizeColumnDefinition

protected List<String> normalizeColumnDefinition(List<String> columnHeader)

Normalizes the headers according to the AdvancedCsvProcessorConfig. It first removes the strings defined in the config.charactersToRemove, then replaces the strings defined in config.charactersToReplace.

Overrides:

normalizeColumnDefinition in class CSVProcessor<T>

Parameters:

columnHeader - the extracted column headers to be used to map them to object fields

Returns:

normalized column headers as define in the AdvancedCsvProcessorConfig. Should allow mapping of the values to objects.

normalizeRow

protected List<String> normalizeRow(List<String> csvLine)

Description copied from class: CSVProcessor

Defines the normalisation of a singular csv line after the header. Adapter method

Overrides:

normalizeRow in class CSVProcessor<T>

Parameters:

csvLine - the split line of a csv file.

Returns:

the normalized csv lines
