TimestampData (Flink : Table : Common 1.12.5 API)

java.lang.Object
- org.apache.flink.table.data.TimestampData

所有已实现的接口:

Comparable<TimestampData>
```
@PublicEvolving
public final class TimestampData
extends Object
implements Comparable<TimestampData>
```
An internal data structure representing data of TimestampType and LocalZonedTimestampType.
This data structure is immutable and consists of a milliseconds and nanos-of-millisecond since 1970-01-01 00:00:00. It might be stored in a compact representation (as a long value) if values are small enough.

    Creates an instance of TimestampData from milliseconds.
    The nanos-of-millisecond field will be set to zero.
    
    参数:
    
    milliseconds - the number of milliseconds since 1970-01-01 00:00:00; a negative number is the number of milliseconds before 1970-01-01 00:00:00
  - fromEpochMillis
```
public static TimestampData fromEpochMillis(long milliseconds,
                                            int nanosOfMillisecond)
```
    Creates an instance of TimestampData from milliseconds and a nanos-of-millisecond.
    
    参数:
    
    milliseconds - the number of milliseconds since 1970-01-01 00:00:00; a negative number is the number of milliseconds before 1970-01-01 00:00:00
    
    nanosOfMillisecond - the nanoseconds within the millisecond, from 0 to 999,999
  - fromLocalDateTime
```
public static TimestampData fromLocalDateTime(java.time.LocalDateTime dateTime)
```
    Creates an instance of TimestampData from an instance of LocalDateTime.
    
    参数:
    
    dateTime - an instance of LocalDateTime
  - fromTimestamp
```
public static TimestampData fromTimestamp(Timestamp timestamp)
```
    Creates an instance of TimestampData from an instance of Timestamp.
    
    参数:
    
    timestamp - an instance of Timestamp
  - fromInstant
```
public static TimestampData fromInstant(java.time.Instant instant)
```
    Creates an instance of TimestampData from an instance of Instant.
    
    参数:
