public final Enum CsvReadFeature

Feature that allows accepting "hash comments" by default, similar to CsvSchema#withAllowComments(boolean). If enabled, such comments are by default allowed on all columns of all documents.

Feature that allows there to be a trailing single extraneous data column that is empty. When this feature is disabled, any extraneous column, regardless of content will cause an exception to be thrown. Disabling this feature is only useful when IGNORE_TRAILING_UNMAPPABLE is also disabled.

Feature that enables coercing an empty String to `null`.

Note that if this setting is enabled, EMPTY_UNQUOTED_STRING_AS_NULL has no effect. Feature is disabled by default for backwards compatibility.

Feature that enables coercing an empty un-quoted String to `null`. This feature allow differentiating between an empty quoted String and an empty un-quoted String.

Note that this feature is only considered if EMPTY_STRING_AS_NULL is disabled.

Feature is disabled by default for backwards compatibility.

Feature that allows failing (with a CsvReadException) in cases where number of column values encountered is less than number of columns declared in the active schema ("missing columns").

Note that this feature has precedence over INSERT_NULLS_FOR_MISSING_COLUMNS

Feature is disabled by default.

Feature that allows failing (with a CsvReadException) in cases where number of header columns encountered is less than number of columns declared in the active schema (if there is one).

Feature is enabled by default.

Feature that allows ignoring of unmappable "extra" columns; that is, values for columns that appear after columns for which types are defined. When disabled, an exception is thrown for such column values, but if enabled, they are silently ignored.

Feature is disabled by default.

Feature that allows "inserting" virtual key / `null` value pairs in case a row contains fewer columns than declared by configured schema. This typically has the effect of forcing an explicit `null` assigment (or corresponding "null value", if so configured) at databinding level. If disabled, no extra work is done and values for "missing" columns are not exposed as part of the token stream.

Note that this feature is only considered if FAIL_ON_MISSING_COLUMNS is disabled.

Feature is disabled by default.

Feature that allows skipping input lines that are completely empty or blank (composed only of whitespace), instead of being decoded as lines of just a single column with an empty/blank String value (or, depending on binding, `null`).

Feature is disabled by default.

Feature determines whether spaces around separator characters (commas) in header line entries (header names) are to be automatically trimmed before being reported or not. Note that this does NOT force trimming of possible white space from within double-quoted values, but only those surrounding unquoted values (white space outside of double-quotes is never included regardless of trimming).

Default value is true.

Feature determines whether spaces around separator characters (commas) are to be automatically trimmed before being reported or not. Note that this does NOT force trimming of possible white space from within double-quoted values, but only those surrounding unquoted values (white space outside of double-quotes is never included regardless of trimming).

Default value is false, as per RFC-4180.

Feature that determines how stream of records (usually CSV lines, but sometimes multiple lines when line-feeds are included in quoted values) is exposed: either as a sequence of Objects (false), or as an Array of Objects (true). Using stream of Objects is convenient when using ObjectMapper.readValues(...) and array of Objects convenient when binding to Lists or arrays of values.

Default value is false, meaning that by default a CSV document is exposed as a sequence of root-level Object entries.
