ContentCoding (Apache HttpClient 5.6 API)

java.lang.Object
- java.lang.Enum<ContentCoding>
- - org.apache.hc.client5.http.entity.compress.ContentCoding

All Implemented Interfaces:

Serializable, Comparable<ContentCoding>
```
public enum ContentCoding
extends Enum<ContentCoding>
```
Enumeration of the canonical IANA content-coding tokens supported by HttpClient for HTTP request and response bodies.
Each constant corresponds to the standard token used in the Content-Encoding and Accept-Encoding headers. Some codings (e.g. Brotli, Zstandard, XZ/LZMA) may require additional helper libraries at runtime.

Since:

5.6

- Method Detail
  - values
```
public static ContentCoding[] 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 (ContentCoding c : ContentCoding.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ContentCoding 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
  - token
```
public String token()
```
    Returns the standard IANA token string for this content-coding.
    
    Returns:
    
    the lowercase token used in HTTP headers
  - fromToken
```
public static ContentCoding fromToken(String token)
```
    Lookup an enum by its token (case‐insensitive), or null if none matches.
    This method is backed by a static, pre‐populated map so the lookup is O(1) instead of O(n).
    
    Parameters:
    
    token - the content‐coding token to look up
    
    Returns:
    
    the matching enum constant, or null if none
