Method Summary

All Methods Instance Methods Concrete Methods Deprecated Methods
Modifier and Type	Method	Description
`Rowtime`	`timestampsFromExtractor(TimestampExtractor extractor)`	Deprecated. Sets a custom timestamp extractor to be used for the rowtime attribute.
`Rowtime`	`timestampsFromField(String fieldName)`	Deprecated. Sets a built-in timestamp extractor that converts an existing `Long` or `Types.SQL_TIMESTAMP` field into the rowtime attribute.
`Rowtime`	`timestampsFromSource()`	Deprecated. Sets a built-in timestamp extractor that converts the assigned timestamps from a DataStream API record into the rowtime attribute and thus preserves the assigned timestamps from the source.
`Map<String,String>`	`toProperties()`	Deprecated. Converts this descriptor into a set of properties.
`Rowtime`	`watermarksFromSource()`	Deprecated. Sets a built-in watermark strategy which indicates the watermarks should be preserved from the underlying DataStream API and thus preserves the assigned watermarks from the source.
`Rowtime`	`watermarksFromStrategy(WatermarkStrategy strategy)`	Deprecated. Sets a custom watermark strategy to be used for the rowtime attribute.
`Rowtime`	`watermarksPeriodicAscending()`	Deprecated. Sets a built-in watermark strategy for ascending rowtime attributes.
`Rowtime`	`watermarksPeriodicBounded(long delay)`	Deprecated. Sets a built-in watermark strategy for rowtime attributes which are out-of-order by a bounded time interval.

  - timestampsFromField
```
public Rowtime timestampsFromField(String fieldName)
```
    Deprecated.
    
    Sets a built-in timestamp extractor that converts an existing Long or Types.SQL_TIMESTAMP field into the rowtime attribute.
    
    Parameters:
    
    fieldName - The field to convert into a rowtime attribute.
  - timestampsFromSource
```
public Rowtime timestampsFromSource()
```
    Deprecated.
    
    Sets a built-in timestamp extractor that converts the assigned timestamps from a DataStream API record into the rowtime attribute and thus preserves the assigned timestamps from the source.
    Note: This extractor only works in streaming environments.
  - timestampsFromExtractor
```
public Rowtime timestampsFromExtractor(TimestampExtractor extractor)
```
    Deprecated.
    
    Sets a custom timestamp extractor to be used for the rowtime attribute.
    
    Parameters:
    
    extractor - The TimestampExtractor to extract the rowtime attribute from the physical type.
  - watermarksPeriodicAscending
```
public Rowtime watermarksPeriodicAscending()
```
    Deprecated.
    
    Sets a built-in watermark strategy for ascending rowtime attributes.
    Emits a watermark of the maximum observed timestamp so far minus 1. Rows that have a timestamp equal to the max timestamp are not late.
  - watermarksPeriodicBounded
```
public Rowtime watermarksPeriodicBounded(long delay)
```
    Deprecated.
    
    Sets a built-in watermark strategy for rowtime attributes which are out-of-order by a bounded time interval.
    Emits watermarks which are the maximum observed timestamp minus the specified delay.
    
    Parameters:
    
    delay - delay in milliseconds
  - watermarksFromSource
```
public Rowtime watermarksFromSource()
```
    Deprecated.
    
    Sets a built-in watermark strategy which indicates the watermarks should be preserved from the underlying DataStream API and thus preserves the assigned watermarks from the source.
  - watermarksFromStrategy
```
public Rowtime watermarksFromStrategy(WatermarkStrategy strategy)
```
    Deprecated.
    
    Sets a custom watermark strategy to be used for the rowtime attribute.
