InputGroup (Flink : Table : Common 2.0.0 API)

java.lang.Object
- java.lang.Enum<InputGroup>
- - org.apache.flink.table.annotation.InputGroup

All Implemented Interfaces:

Serializable, Comparable<InputGroup>
```
@PublicEvolving
public enum InputGroup
extends Enum<InputGroup>
```
A list of commonly used pre-defined groups of similar types for accepting more than just one data type as an input argument in DataTypeHints.
This list exposes a combination of LogicalTypeFamily and InputTypeStrategies via annotations for convenient inline usage.

- Enum Constant Detail
  - UNKNOWN
```
public static final InputGroup UNKNOWN
```
    Default if no group is specified.
  - ANY
```
public static final InputGroup ANY
```
    Enables input wildcards. Any data type can be passed. The behavior is equal to InputTypeStrategies.ANY.
    Note: The class of the annotated element must be Object as this is the super class of all possibly passed data types.
- Method Detail
  - values
```
public static InputGroup[] 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 (InputGroup c : InputGroup.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static InputGroup 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
