- Enum Constant Detail
  - LEFT_SEMI
```
public static final SemiJoinMode LEFT_SEMI
```
    Output those rows from the left for which there exists a matching row on the right. Output contains only keys/data from the left side.
  - LEFT_ANTI

- Method Detail
  - values
```
public static SemiJoinMode[] 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 (SemiJoinMode c : SemiJoinMode.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SemiJoinMode 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
