- Enum Constant Detail
  - NO_ERROR
```
public static final GrpcUtil.Http2Error NO_ERROR
```
    Servers implementing a graceful shutdown of the connection will send GOAWAY with NO_ERROR. In this case it is important to indicate to the application that the request should be retried (i.e. Status.UNAVAILABLE).
  - PROTOCOL_ERROR

```
public static final GrpcUtil.Http2Error HTTP_1_1_REQUIRED
```
- Method Detail
  - values
```
public static GrpcUtil.Http2Error[] 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 (GrpcUtil.Http2Error c : GrpcUtil.Http2Error.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static GrpcUtil.Http2Error 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
  - code
```
public long code()
```
    Gets the code for this error used on the wire.
  - status
```
public io.grpc.Status status()
```
    Gets the Status associated with this HTTP/2 code.
  - forCode
```
public static GrpcUtil.Http2Error forCode(long code)
```
    Looks up the HTTP/2 error code enum value for the specified code.
    
    Parameters:
    
    code - an HTTP/2 error code value.
    
    Returns:
    
    the HTTP/2 error code enum or null if not found.
  - statusForCode
```
public static io.grpc.Status statusForCode(long code)
```
    Looks up the Status from the given HTTP/2 error code. This is preferred over forCode(code).status(), to more easily conform to HTTP/2:
    Unknown or unsupported error codes MUST NOT trigger any special behavior. These MAY be treated by an implementation as being equivalent to INTERNAL_ERROR.
    
    Parameters:
    
    code - the HTTP/2 error code.
    
    Returns:
    
    a Status representing the given error.
