ResourceType (clients 7.5.12-ce API)

java.lang.Object
- java.lang.Enum<ResourceType>
- - org.apache.kafka.common.resource.ResourceType

All Implemented Interfaces:
Serializable, Comparable<ResourceType>
```
@InterfaceStability.Evolving
public enum ResourceType
extends Enum<ResourceType>
```
Represents a type of resource which an ACL can be applied to. The API for this class is still evolving and we may break compatibility in minor releases, if necessary.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`ANY` In a filter, matches any ResourceType.
`CLUSTER` The cluster as a whole.
`DELEGATION_TOKEN` A token ID.
`GROUP` A consumer group.
`TOPIC` A Kafka topic.
`TRANSACTIONAL_ID` A transactional ID.
`UNKNOWN` Represents any ResourceType which this client cannot understand, perhaps because this client is too old.
`USER` A user principal

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`byte`	`code()` Return the code of this resource.
`static ResourceType`	`fromCode(byte code)` Return the ResourceType with the provided code or `ResourceType.UNKNOWN` if one cannot be found.

  - UNKNOWN
```
public static final ResourceType UNKNOWN
```
    Represents any ResourceType which this client cannot understand, perhaps because this client is too old.

```
public static final ResourceType ANY
```
    In a filter, matches any ResourceType.
  - TOPIC
```
public static final ResourceType TOPIC
```
    A Kafka topic.
  - GROUP
```
public static final ResourceType GROUP
```
    A consumer group.
  - CLUSTER
```
public static final ResourceType CLUSTER
```
    The cluster as a whole.
  - TRANSACTIONAL_ID
```
public static final ResourceType TRANSACTIONAL_ID
```
    A transactional ID.
  - DELEGATION_TOKEN
```
public static final ResourceType DELEGATION_TOKEN
```
    A token ID.
  - USER

public static final ResourceType USER
```
    A user principal
- Method Detail
  - values
```
public static ResourceType[] 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 (ResourceType c : ResourceType.values())
    System.out.println(c);
```
    Returns:
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ResourceType 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
  - fromString
```
public static ResourceType fromString(String str)
                               throws IllegalArgumentException
```
    Parse the given string as an ACL resource type.
    Parameters:
    str - The string to parse.
    Returns:
    The ResourceType, or UNKNOWN if the string could not be matched.
    Throws:
    IllegalArgumentException
  - fromCode
```
public static ResourceType fromCode(byte code)
```
    Return the ResourceType with the provided code or `ResourceType.UNKNOWN` if one cannot be found.
  - code
```
public byte code()
```
    Return the code of this resource.
  - isUnknown
```
public boolean isUnknown()
```
    Return whether this resource type is UNKNOWN.
