public static enum CsvSchema.ColumnType extends Enum<CsvSchema.ColumnType>
JsonToken
that column values are exposed as.| Enum Constant and Description |
|---|
ARRAY
Value will be a multi-value sequence, separated by array element
separator.
|
BOOLEAN
Value is expected to be a boolean ("true", "false") String,
or "null", or empty String (equivalent to null).
|
NUMBER
Value should be a number, but literals "null", "true" and "false"
are also understood, and an empty String is considered null.
|
NUMBER_OR_STRING
Value is taken to be a number (if it matches valid JSON number
formatting rules), literal (null, true or false) or String,
depending on best match.
|
STRING
Default type if not explicitly defined; value will
be presented as
VALUE_STRING by parser,
that is, no type-inference is performed, and value is
not trimmed. |
STRING_OR_LITERAL
Value is considered to be a String, except that tokens
"null", "true" and "false" are recognized as matching
tokens and reported as such;
and values are trimmed (leading/trailing white space)

| Modifier and Type | Method and Description |
|---|---|
static CsvSchema.ColumnType |
valueOf(String name)
Returns the enum constant of this type with the specified name.
|
static CsvSchema.ColumnType[] |
values()
Returns an array containing the constants of this enum type, in
the order they are declared.
|
public static final CsvSchema.ColumnType STRING
VALUE_STRING by parser,
that is, no type-inference is performed, and value is
not trimmed.
Note that this type allows coercion into array, if higher
level application calls
JsonParser.isExpectedStartArrayToken(),
unlike more explicit types.

public static final CsvSchema.ColumnType NUMBER
public static final CsvSchema.ColumnType NUMBER_OR_STRING
public static final CsvSchema.ColumnType BOOLEAN
public static final CsvSchema.ColumnType ARRAY
Note that this type is used for generic concept of multiple values, and
not specifically to match Java arrays: data-binding may match such columns
to Collections as well, or even other types as necessary.

for (CsvSchema.ColumnType c : CsvSchema.ColumnType.values()) System.out.println(c);
