org.apache.logging.log4j.core.pattern.PatternParser
Most of the work of the {@link org.apache.logging.log4j.core.layout.PatternLayout} class is delegated to thePatternParser class.
It is this class that parses conversion patterns and creates a chained list of {@link PatternConverter PatternConverters}.

    /**
     * Constructor.
     * @param pattern The file pattern.
     */
    public PatternProcessor(String pattern) {
        PatternParser parser = createPatternParser();
        List<PatternConverter> converters = new ArrayList<PatternConverter>();
        List<FormattingInfo> fields = new ArrayList<FormattingInfo>();
        parser.parse(pattern, converters, fields);
        FormattingInfo[] infoArray = new FormattingInfo[fields.size()];
        patternFields = fields.toArray(infoArray);
        ArrayPatternConverter[] converterArray = new ArrayPatternConverter[converters.size()];
        patternConverters = converters.toArray(converterArray);
