CsvParser(CsvParserSettings settings)
The CsvParser supports all settings provided by

Allows the parser implementation to handle any value that was being consumed when the end of the input was reached

getDetectedFormat()
Returns the CSV format detected when one of the following settings is enabled:
CommonParserSettings.isLineSeparatorDetectionEnabled()
CsvParserSettings.isDelimiterDetectionEnabled()
CsvParserSettings.isQuoteDetectionEnabled()
The detected format will be available once the parsing process is initialized (i.e. |

Allows the parser implementation to traverse the input buffer before the parsing process starts, in order to enable automatic configuration and discovery of data formats.

Parser-specific implementation for reading a single record from the input.

AbstractParser
The AbstractParser handles the initialization and processing of the input until it is ready to be parsed.
It then delegates the input to the parser-specific implementation defined by AbstractParser.parseRecord()
. In general, an implementation of AbstractParser.parseRecord()
will perform the following steps:
CharAppender
) so the next call to output.appender.append(ch) will be store the character of the next parsed value Once the AbstractParser.parseRecord()
returns, the AbstractParser takes over and handles the information (generally, reorganizing it and passing it on to a RowProcessor
).
After the record processing, the AbstractParser reads the next characters from the input, delegating control again to the parseRecord() implementation for processing of the next record.
This cycle repeats until the reading process is stopped by the user, the input is exhausted, or an error happens.
In case of errors, the unchecked exception TextParsingException
will be thrown and all resources in use will be closed automatically. The exception should contain the cause and more information about where in the input the error happened.
