public enum AclOperation
extends Enum<AclOperation>

Represents an operation which an ACL grants or denies permission to perform. Some operations imply other operations:

• ALLOW ALL implies ALLOW everything
• DENY ALL implies DENY everything
• ALLOW READ implies ALLOW DESCRIBE
• ALLOW WRITE implies ALLOW DESCRIBE
• ALLOW DELETE implies ALLOW DESCRIBE
• ALLOW ALTER implies ALLOW DESCRIBE
• ALLOW ALTER_CONFIGS implies ALLOW DESCRIBE_CONFIGS

Method Details

values

public static AclOperation[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static AclOperation valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

Parse the given string as an ACL operation.

Parameters:

str - The string to parse.

Returns:

The AclOperation, or UNKNOWN if the string could not be matched.

Throws:

IllegalArgumentException

fromCode

public static AclOperation fromCode(byte code)

Return the AclOperation with the provided code or `AclOperation.UNKNOWN` if one cannot be found.

code

public byte code()

Return the code of this operation.

isUnknown

public boolean isUnknown()

Return true if this operation is UNKNOWN.
