◆  GetValue()

const MAXON_ATTRIBUTE_FORCE_INLINE T& GetValue ( ) const &

Returns the result value. A DebugAssert will trigger if this is invoked when there is an error.

返回
Result 值。

◆  UncheckedGetValue()

const MAXON_ATTRIBUTE_FORCE_INLINE T& UncheckedGetValue ( ) const &

Returns the result value. In case of an error there is no value, then this function returns a null value.

返回
Result value (or a null value in case of an error).

◆  MAXON_MEMBER_ACCESSORS() [1/2]

MAXON_MEMBER_ACCESSORS ( T  ,
GetValue    
)

◆  MAXON_MEMBER_ACCESSORS() [2/2]

MAXON_MEMBER_ACCESSORS ( T  ,
UncheckedGetValue    
)

◆  GetValueAndError() [1/4]

const MAXON_ATTRIBUTE_FORCE_INLINE T& GetValueAndError ( ThreadReferencedError &  error ) const &

Returns the result value and error. If there is an error, the parameter #error will be set to the error and a null value is returned.

参数
[out] error This parameter receives the error (or a nullptr if there is no error).
返回
Result value (or a null value in case of an error).

◆  GetValueAndError() [2/4]

MAXON_ATTRIBUTE_FORCE_INLINE T GetValueAndError ( ThreadReferencedError &  error ) &&

Returns the result value and error. If there is an error, the parameter #error will be set to the error and a null value is returned.

参数
[out] error This parameter receives the error (or a nullptr if there is no error).
返回
Result value (or a null value in case of an error).

◆  GetValueAndError() [3/4]

const MAXON_ATTRIBUTE_FORCE_INLINE T& GetValueAndError ( Error &  error ) const &

Returns the result value and error. If there is an error, the parameter #error will be set to the error and a null value is returned.

参数
[out] error This parameter receives the error (or a nullptr if there is no error).
返回
Result value (or a null value in case of an error).

◆  GetValueAndError() [4/4]

MAXON_ATTRIBUTE_FORCE_INLINE T GetValueAndError ( Error &  error ) &&

Returns the result value and error. If there is an error, the parameter #error will be set to the error and a null value is returned.

参数
[out] error This parameter receives the error (or a nullptr if there is no error).
返回
Result value (or a null value in case of an error).

◆  GetErrorStorage() [1/2]

const MAXON_ATTRIBUTE_FORCE_INLINE ThreadReferencedError & GetErrorStorage ( ) const

Returns a reference to the ThreadReferencedError storage in which the Result stores its error.

返回
The ThreadReferencedError where the error (if any) is stored.

◆  GetErrorStorage() [2/2]

MAXON_ATTRIBUTE_FORCE_INLINE ThreadReferencedError & GetErrorStorage ( )

Returns a reference to the ThreadReferencedError storage in which the Result stores its error.

返回
The ThreadReferencedError where the error (if any) is stored.
