Document

Converts the character to a String that contains the one character.

For ASCII 7 bit characters, this uses a cache that will return the same String object each time.

If null is passed in, null will be returned.

 CharUtils.toString(null) = null CharUtils.toString(' ')  = " " CharUtils.toString('A')  = "A" 

Usage

From source file:org.apache.nifi.csv.JacksonCSVRecordReader.java

public JacksonCSVRecordReader(final InputStream in, final ComponentLog logger, final RecordSchema schema,
        final CSVFormat csvFormat, final boolean hasHeader, final boolean ignoreHeader, final String dateFormat,
        final String timeFormat, final String timestampFormat, final String encoding) throws IOException {
    super(logger, schema, hasHeader, ignoreHeader, dateFormat, timeFormat, timestampFormat);

    final Reader reader = new InputStreamReader(new BOMInputStream(in));

    CsvSchema.Builder csvSchemaBuilder = CsvSchema.builder().setColumnSeparator(csvFormat.getDelimiter())
            .setLineSeparator(csvFormat.getRecordSeparator())
            // Can only use comments in Jackson CSV if the correct marker is set
            .setAllowComments("#".equals(CharUtils.toString(csvFormat.getCommentMarker())))
            // The call to setUseHeader(false) in all code paths is due to the way Jackson does data binding/mapping. Missing or extra columns may not
            // be handled correctly when using the header for mapping.
            .setUseHeader(false);/*www . j a va2s .  c  o m*/

    csvSchemaBuilder = (csvFormat.getQuoteCharacter() == null) ? csvSchemaBuilder
            : csvSchemaBuilder.setQuoteChar(csvFormat.getQuoteCharacter());
    csvSchemaBuilder = (csvFormat.getEscapeCharacter() == null) ? csvSchemaBuilder
            : csvSchemaBuilder.setEscapeChar(csvFormat.getEscapeCharacter());

    if (hasHeader) {
        if (ignoreHeader) {
            csvSchemaBuilder = csvSchemaBuilder.setSkipFirstDataRow(true);

    CsvSchema csvSchema = csvSchemaBuilder.build();

    // Add remaining config options to the mapper
    List<CsvParser.Feature> features = new ArrayList<>();

        features.add(CsvParser.Feature.SKIP_EMPTY_LINES);
    }
    if (csvFormat.getTrim()) {
        features.add(CsvParser.Feature.TRIM_SPACES);
    }

    ObjectReader objReader = mapper.readerFor(String[].class).with(csvSchema)
            .withFeatures(features.toArray(new CsvParser.Feature[features.size()]));

    recordStream = objReader.readValues(reader);
