Enum Constant Summary

Enum Constants
Enum Constant and Description
`ABORTED` The operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc.
`ALREADY_EXISTS` Some entity that we attempted to create (e.g., file or directory) already exists.
`CANCELLED` The operation was cancelled (typically by the caller).
`DATA_LOSS` Unrecoverable data loss or corruption.
`DEADLINE_EXCEEDED` Deadline expired before operation could complete.
`FAILED_PRECONDITION` Operation was rejected because the system is not in a state required for the operation's execution.
`INTERNAL` Internal errors.
`INVALID_ARGUMENT` Client specified an invalid argument.
`NOT_FOUND` Some requested entity (e.g., file or directory) was not found.
`OK` The operation completed successfully.
`OUT_OF_RANGE` Operation was attempted past the valid range.
`PERMISSION_DENIED` The caller does not have permission to execute the specified operation.
`RESOURCE_EXHAUSTED` Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
`UNAUTHENTICATED` The request does not have valid authentication credentials for the operation.
`UNAVAILABLE` The service is currently unavailable.
`UNIMPLEMENTED` Operation is not implemented or not supported/enabled in this service.
`UNKNOWN` Unknown error.

- Enum Constant Detail
  - OK
```
public static final Status.CanonicalCode OK
```
    The operation completed successfully.
    
    Since:
    
    0.5
  - CANCELLED
```
public static final Status.CanonicalCode CANCELLED
```
    The operation was cancelled (typically by the caller).
    
    Since:
    
    0.5
  - UNKNOWN
```
public static final Status.CanonicalCode UNKNOWN
```
    Unknown error. An example of where this error may be returned is if a Status value received from another address space belongs to an error-space that is not known in this address space. Also errors raised by APIs that do not return enough error information may be converted to this error.
    
    Since:
    
    0.5
  - INVALID_ARGUMENT
```
public static final Status.CanonicalCode INVALID_ARGUMENT
```
    Client specified an invalid argument. Note that this differs from FAILED_PRECONDITION. INVALID_ARGUMENT indicates arguments that are problematic regardless of the state of the system (e.g., a malformed file name).
    
    Since:
    
    0.5
  - DEADLINE_EXCEEDED
```
public static final Status.CanonicalCode DEADLINE_EXCEEDED
```
    Deadline expired before operation could complete. For operations that change the state of the system, this error may be returned even if the operation has completed successfully. For example, a successful response from a server could have been delayed long enough for the deadline to expire.
    
    Since:
    
    0.5
  - NOT_FOUND
```
public static final Status.CanonicalCode NOT_FOUND
```
    Some requested entity (e.g., file or directory) was not found.
    
    Since:
    
    0.5
  - ALREADY_EXISTS
```
public static final Status.CanonicalCode ALREADY_EXISTS
```
    Some entity that we attempted to create (e.g., file or directory) already exists.
    
    Since:
    
    0.5
  - PERMISSION_DENIED
```
public static final Status.CanonicalCode PERMISSION_DENIED
```
    The caller does not have permission to execute the specified operation. PERMISSION_DENIED must not be used for rejections caused by exhausting some resource (use RESOURCE_EXHAUSTED instead for those errors). PERMISSION_DENIED must not be used if the caller cannot be identified (use UNAUTHENTICATED instead for those errors).
    
    Since:
    
    0.5
  - RESOURCE_EXHAUSTED
```
public static final Status.CanonicalCode RESOURCE_EXHAUSTED
```
    Some resource has been exhausted, perhaps a per-user quota, or perhaps the entire file system is out of space.
    
    Since:
    
    0.5
  - FAILED_PRECONDITION
```
public static final Status.CanonicalCode FAILED_PRECONDITION
```
    Operation was rejected because the system is not in a state required for the operation's execution. For example, directory to be deleted may be non-empty, an rmdir operation is applied to a non-directory, etc.
    A litmus test that may help a service implementor in deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE: (a) Use UNAVAILABLE if the client can retry just the failing call. (b) Use ABORTED if the client should retry at a higher-level (e.g., restarting a read-modify-write sequence). (c) Use FAILED_PRECONDITION if the client should not retry until the system state has been explicitly fixed. E.g., if an "rmdir" fails because the directory is non-empty, FAILED_PRECONDITION should be returned since the client should not retry unless they have first fixed up the directory by deleting files from it.
    
    Since:
    
    0.5
  - ABORTED
```
public static final Status.CanonicalCode ABORTED
```
    The operation was aborted, typically due to a concurrency issue like sequencer check failures, transaction aborts, etc.
    See litmus test above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE.
    
    Since:
    
    0.5
  - OUT_OF_RANGE
```
public static final Status.CanonicalCode OUT_OF_RANGE
```
    Operation was attempted past the valid range. E.g., seeking or reading past end of file.
    Unlike INVALID_ARGUMENT, this error indicates a problem that may be fixed if the system state changes. For example, a 32-bit file system will generate INVALID_ARGUMENT if asked to read at an offset that is not in the range [0,2^32-1], but it will generate OUT_OF_RANGE if asked to read from an offset past the current file size.
    There is a fair bit of overlap between FAILED_PRECONDITION and OUT_OF_RANGE. We recommend using OUT_OF_RANGE (the more specific error) when it applies so that callers who are iterating through a space can easily look for an OUT_OF_RANGE error to detect when they are done.
    
    Since:
    
    0.5
  - UNIMPLEMENTED
```
public static final Status.CanonicalCode UNIMPLEMENTED
```
    Operation is not implemented or not supported/enabled in this service.
    
    Since:
    
    0.5
  - INTERNAL
```
public static final Status.CanonicalCode INTERNAL
```
    Internal errors. Means some invariants expected by underlying system has been broken. If you see one of these errors, something is very broken.
    
    Since:
    
    0.5
  - UNAVAILABLE
```
public static final Status.CanonicalCode UNAVAILABLE
```
    The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.
    See litmus test above for deciding between FAILED_PRECONDITION, ABORTED, and UNAVAILABLE.
    
    Since:
    
    0.5
  - DATA_LOSS
```
public static final Status.CanonicalCode DATA_LOSS
```
    Unrecoverable data loss or corruption.
    
    Since:
    
    0.5
  - UNAUTHENTICATED
```
public static final Status.CanonicalCode UNAUTHENTICATED
```
    The request does not have valid authentication credentials for the operation.

  - values
```
public static Status.CanonicalCode[] 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 (Status.CanonicalCode c : Status.CanonicalCode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Status.CanonicalCode 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
  - value
```
public int value()
```
    Returns the numerical value of the code.
    
    Returns:
    
    the numerical value of the code.
