@PublicEvolving
public final class ZonedTimestampType
extends DataType

Data type of a timestamp WITH time zone consisting of year-month-day hour:minute:second[.fractional] zone with up to nanosecond precision and values ranging from 0000-01-01 00:00:00.000000000 +14:59 to 9999-12-31 23:59:59.999999999 -14:59. Compared to the SQL standard, leap seconds (23:59:60 and 23:59:61) are not supported as the semantics are closer to OffsetDateTime.

The serialized string representation is TIMESTAMP(p) WITH TIME ZONE where p is the number of digits of fractional seconds (=precision). p must have a value between 0 and 9 (both inclusive). If no precision is specified, p is equal to 6.

Compared to LocalZonedTimestampType, the time zone offset information is physically stored in every datum. It is used individually for every computation, visualization, or communication to external systems.

A conversion from ZonedDateTime ignores the zone ID.

ZonedTimestampType

public ZonedTimestampType(boolean isNullable,
                          int precision)

Internal constructor that allows attaching additional metadata about time attribute properties. The additional metadata does not affect equality or serializability.

ZonedTimestampType

public ZonedTimestampType(int precision)

ZonedTimestampType

public ZonedTimestampType()

方法详细资料

getPrecision

public int getPrecision()

copy

public DataType copy(boolean isNullable)

从类复制的说明: DataType

Returns a deep copy of this type with possibly different nullability.

指定者:

copy 在类中 DataType

参数:

isNullable - the intended nullability of the copied type

返回:

a deep copy

asSerializableString

public String asSerializableString()

从类复制的说明: DataType

Returns a string that fully serializes this instance. The serialized string can be used for transmitting or persisting a type.

指定者:

asSerializableString 在类中 DataType

返回:

detailed string for transmission or persistence

asSummaryString

public String asSummaryString()

从类复制的说明: DataType

Returns a string that summarizes this type for printing to a console. An implementation might shorten long names or skips very specific properties.

Use DataType.asSerializableString() for a type string that fully serializes this instance.

覆盖:

asSummaryString 在类中 DataType

返回:

summary string of this type for debugging purposes

getChildren

public List<DataType> getChildren()

指定者:

getChildren 在类中 DataType

accept

public <R> R accept(DataTypeVisitor<R> visitor)

指定者:

accept 在类中 DataType

equals

public boolean equals(Object o)

覆盖:

equals 在类中 DataType

hashCode

public int hashCode()

覆盖:

hashCode 在类中 DataType
