ColumnMetadata.Kind (apache-cassandra API)

java.lang.Object
- java.lang.Enum<ColumnMetadata.Kind>
- - org.apache.cassandra.schema.ColumnMetadata.Kind

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ColumnMetadata.Kind>

Enclosing class:

ColumnMetadata
```
public static enum ColumnMetadata.Kind
extends java.lang.Enum<ColumnMetadata.Kind>
```
The type of CQL3 column this definition represents. There is 4 main type of CQL3 columns: those parts of the partition key, those parts of the clustering columns and amongst the others, regular and static ones. IMPORTANT: this enum is serialized as toString() and deserialized by calling Kind.valueOf(), so do not override toString() or rename existing values.

public static ColumnMetadata.Kind[] 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 (ColumnMetadata.Kind c : ColumnMetadata.Kind.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ColumnMetadata.Kind valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
