java.lang.Enum<CsvGenerator.Feature>

com.fasterxml.jackson.dataformat.csv.CsvGenerator.Feature

All Implemented Interfaces:

Serializable, Comparable<CsvGenerator.Feature>

Enclosing class:

CsvGenerator

public static enum CsvGenerator.Feature
extends Enum<CsvGenerator.Feature>

Enumeration that defines all togglable features for CSV writers (if any: currently none)

Enum Constant Summary

Enum Constants

Enum Constant and Description
OMIT_MISSING_TAIL_COLUMNS Feature that determines whether columns without matching value may be omitted, when they are the last values of the row.
STRICT_CHECK_FOR_QUOTING Feature that determines how much work is done before determining that a column value requires quoting: when set as true, full check is made to only use quoting when it is strictly necessary; but when false, a faster but more conservative check is made, and possibly quoting is used for values that might not need it.

Enum Constant Detail

STRICT_CHECK_FOR_QUOTING

public static final CsvGenerator.Feature STRICT_CHECK_FOR_QUOTING

Feature that determines how much work is done before determining that a column value requires quoting: when set as true, full check is made to only use quoting when it is strictly necessary; but when false, a faster but more conservative check is made, and possibly quoting is used for values that might not need it. Trade-offs is basically between optimal/minimal quoting (true), and faster handling (false). Faster check involves only checking first N characters of value, as well as possible looser checks.

Note, however, that regardless setting, all values that need to be quoted will be: it is just that when set to false, other values may also be quoted (to avoid having to do more expensive checks).

Default value is false for "loose" (approximate, conservative) checking.

Since:

2.4

OMIT_MISSING_TAIL_COLUMNS

public static final CsvGenerator.Feature OMIT_MISSING_TAIL_COLUMNS

Feature that determines whether columns without matching value may be omitted, when they are the last values of the row. If true, values and separators between values may be omitted, to slightly reduce length of the row; if false, separators need to stay in place and values are indicated by empty Strings.

Since:

2.4

Method Detail

values

public static CsvGenerator.Feature[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CsvGenerator.Feature c : CsvGenerator.Feature.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CsvGenerator.Feature valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

collectDefaults

public static int collectDefaults()

Method that calculates bit set (flags) of all features that are enabled by default.

enabledIn

public boolean enabledIn(int flags)

enabledByDefault

public boolean enabledByDefault()

getMask

public int getMask()
