枚举 SchemaChangeResponse.ResponseCode

java.lang.Object

java.lang.Enum<SchemaChangeResponse.ResponseCode>

org.apache.flink.cdc.runtime.operators.schema.event.SchemaChangeResponse.ResponseCode

所有已实现的接口:

Serializable, Comparable<SchemaChangeResponse.ResponseCode>

封闭类:

SchemaChangeResponse

public static enum SchemaChangeResponse.ResponseCode
extends Enum<SchemaChangeResponse.ResponseCode>

Schema Change Response status code.

- Accepted: Requested schema change request has been accepted exclusively. Any other schema change requests will be blocked.

- Busy: Schema registry is currently busy processing another schema change request.

- Duplicate: This schema change request has been submitted before, possibly by another paralleled subTask.

- Ignored: This schema change request has been assessed, but no actual evolution is required. Possibly caused by LENIENT mode or merging table strategies.

valueOf

public static SchemaChangeResponse.ResponseCode valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
