Casing (Apache Calcite Avatica 1.15.0 API)

java.lang.Object
- java.lang.Enum<Casing>
- - org.apache.calcite.avatica.util.Casing

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Casing>
```
public enum Casing
extends java.lang.Enum<Casing>
```
Policy for converting case of identifiers before storing them.
A database often has policies for quoted versus unquoted identifiers. For example, Oracle converts unquoted identifiers to upper-case, but quoted identifiers are unchanged.

Enum Constant Summary

Enum Constants
Enum Constant	Description
`TO_LOWER`	Identifiers are converted to lower-case.
`TO_UPPER`	Identifiers are converted to upper-case.
`UNCHANGED`	The case of identifiers is not changed.

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