SegmentWithState.SegmentState (druid-server 29.0.1 API)

java.lang.Object
- java.lang.Enum<SegmentWithState.SegmentState>
- - org.apache.druid.segment.realtime.appenderator.SegmentWithState.SegmentState

All Implemented Interfaces:

Serializable, Comparable<SegmentWithState.SegmentState>

Enclosing class:

SegmentWithState
```
public static enum SegmentWithState.SegmentState
extends Enum<SegmentWithState.SegmentState>
```
Segment state transition is different in BatchAppenderatorDriver and StreamAppenderatorDriver. When a new segment is created, its state is APPENDING. - In stream ingestion, the state of some segments can be changed to the APPEND_FINISHED state. Data is not appended to these segments anymore, and they are waiting for beging published. See StreamAppenderatorDriver.moveSegmentOut(String, List). - In batch ingestion, the state of some segments can be changed to the PUSHED_AND_DROPPED state. These segments are pushed and dropped from the local storage, but not published yet. See BatchAppenderatorDriver.pushAndClear(Collection, long). Note: If you need to add more states which are used differently in batch and streaming ingestion, consider moving SegmentState to BatchAppenderatorDriver and StreamAppenderatorDriver.

```
public static SegmentWithState.SegmentState[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (SegmentWithState.SegmentState c : SegmentWithState.SegmentState.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SegmentWithState.SegmentState valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - fromString
