public class ParserOutput
extends java.lang.Object
```
The ParserOutput is the component that manages records parsed by AbstractParser and their values. It is solely responsible for deciding when:
- parsed records should be reordered according to the fields selected in CommonSettings
- characters and values parsed in AbstractParser.parseRecord() should be retained or discarded
- input headers should be loaded from the records parsed in AbstractParser.parseRecord() or from CommonSettings.getHeaders()
Implementations of this class are made available to concrete parser implementations of AbstractParser.

- Field Detail
  - column
```
protected int column
```
    Keeps track of the current column being parsed in the input. Calls to valueParsed() and emptyParsed() will increase the column count. This value is reset to zero after a row is parsed.
  - parsedValues
```
protected final java.lang.String[] parsedValues
```
    Stores the values parsed for a record.
  - appenders
```
private final CharAppender[] appenders
```
    Stores (shared) references to CharAppender for each potential column (as given by CommonSettings.getMaxColumns()).
    Fields that are not selected will receive an instance of NoopCharAppender so all parser calls in AbstractParser.parseRecord() to appender will do nothing.
    Selected fields (given by CommonParserSettings) will receive a functional CharAppender.
  - settings
```
protected final CommonParserSettings<?> settings
```
  - skipEmptyLines
```
private final boolean skipEmptyLines
```
  - nullValue
```
private final java.lang.String nullValue
```
  - appender
```
public CharAppender appender
```
    The appender available to parsers for accumulating characters read from the input.
    This attribute is assigned to different instances of CharAppender during parsing process, namely, a (potentially) different CharAppender for each parsed column, taken from appenders[column]
  - appenderInstance
```
private final CharAppender appenderInstance
```
  - columnsToExtractInitialized
```
private boolean columnsToExtractInitialized

public boolean trim
```
  - pendingRecords
```
public final java.util.Deque<java.lang.String[]> pendingRecords
```
  - parsedHeaders
```
java.lang.String[] parsedHeaders
```
    Headers parsed from the input when CommonParserSettings.headerExtractionEnabled is true, irrespective of any user-provided headers in CommonSettings.getHeaders()
  - parser
```
private final AbstractParser<?> parser

```
public java.lang.String[] getHeaderAsStringArray()
```
  - getHeaders
```
public NormalizedString[] getHeaders()
