Class StdDateFormat

java.lang.Object

java.text.Format

java.text.DateFormat

com.fasterxml.jackson.databind.util.StdDateFormat

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class StdDateFormat
extends java.text.DateFormat

Default DateFormat implementation used by standard Date serializers and deserializers. For serialization defaults to using an ISO-8601 compliant format (format String "yyyy-MM-dd'T'HH:mm:ss.SSSZ") and for deserialization, both ISO-8601 and RFC-1123.
Note that `Z` in format String refers to RFC-822 timezone notation which produces values like "-0800" -- that is, full minute/hour combo without colon, and not using `Z` as alias for "+0000".

Note also that to enable use of colon in timezone is possible by using method withColonInTimeZone(boolean) for creating new differently configured format instance.

Method Detail

getDefaultTimeZone

public static java.util.TimeZone getDefaultTimeZone()

withTimeZone

public StdDateFormat withTimeZone(java.util.TimeZone tz)

Method used for creating a new instance with specified timezone; if no timezone specified, defaults to the default timezone (UTC).

withLocale

public StdDateFormat withLocale(java.util.Locale loc)

"Mutant factory" method that will return an instance that uses specified Locale: either this instance (if setting would not change), or newly constructed instance with different Locale to use.

withLenient

public StdDateFormat withLenient(java.lang.Boolean b)

"Mutant factory" method that will return an instance that has specified leniency setting: either this instance (if setting would not change), or newly constructed instance.

Since:

2.9

withColonInTimeZone

public StdDateFormat withColonInTimeZone(boolean b)

"Mutant factory" method that will return an instance that has specified handling of colon when serializing timezone (timezone either written like +0500 or +05:00): either this instance (if setting would not change), or newly constructed instance with desired setting for colon inclusion.

NOTE: does NOT affect deserialization as colon is optional accepted but not required -- put another way, either serialization is accepted by this class.

Since:

2.9.1

clone

public StdDateFormat clone()

Overrides:

clone in class java.text.DateFormat

getISO8601Format

@Deprecated
public static java.text.DateFormat getISO8601Format(java.util.TimeZone tz,
                                                                java.util.Locale loc)

Deprecated. Since 2.9

Method for getting a non-shared DateFormat instance that uses specified timezone and can handle simple ISO-8601 compliant date format.

Since:

2.4

getRFC1123Format

@Deprecated
public static java.text.DateFormat getRFC1123Format(java.util.TimeZone tz,
                                                                java.util.Locale loc)

Deprecated. Since 2.9

Method for getting a non-shared DateFormat instance that uses specific timezone and can handle RFC-1123 compliant date format.

Since:

2.4

getTimeZone

public java.util.TimeZone getTimeZone()

Overrides:

getTimeZone in class java.text.DateFormat

setTimeZone

public void setTimeZone(java.util.TimeZone tz)

Overrides:

setTimeZone in class java.text.DateFormat

setLenient

public void setLenient(boolean enabled)

Need to override since we need to keep track of leniency locally, and not via underlying Calendar instance like base class does.

Overrides:

setLenient in class java.text.DateFormat

isLenient

public boolean isLenient()

Overrides:

isLenient in class java.text.DateFormat

isColonIncludedInTimeZone

public boolean isColonIncludedInTimeZone()

Accessor for checking whether this instance would include colon within timezone serialization or not: if {code true}, timezone offset is serialized like -06:00; if {code false} as -0600.

NOTE: only relevant for serialization (formatting), as deserialization (parsing) always accepts optional colon but does not require it, regardless of this setting.

Returns:

true if a colon is to be inserted between the hours and minutes of the TZ offset when serializing as String; otherwise false
