java.lang.Enum<StatusCode>

com.scalar.dl.ledger.service.StatusCode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<StatusCode>

public enum StatusCode
extends java.lang.Enum<StatusCode>

Status code of registration or execution requests to ledger.

The 2xx class of status code indicates that the request has succeeded.

The 3xx class of status code indicates that an asset record in the database is in an invalid state and possibly tampered.

The 4xx class of status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., invalid signature, invalid key pair, execution error inside contracts or contract is not found).

The 5xx class of status code indicates that the ledger server encountered an unexpected condition that prevented it from fulfilling the request.

The 6xx class of status code indicates that the client encountered an unexpected condition that prevented it from fulfilling the request.

Method Detail

values

public static StatusCode[] 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 (StatusCode c : StatusCode.values())
    System.out.println(c);

Returns:

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

valueOf

public static StatusCode 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
