Detailed Description

Manipulate Maya Status codes.

This class facilitates API level error handling. It encapsulates the status code and the internal MAYA error code as return by API functions. The user can query, set, print the error code along with the error description.

Constructor & Destructor Documentation

MStatus ( )
inline

The default class constructor.

It initializes the internal detailed status code to kSuccess.

MStatus ( MStatus::MStatusCode  status)

The constructor that takes a MStatus::MStatusCode.

Initializes the internal detailed status code to status

Parameters
[in]statusThe initial detailed status code.
MStatus ( const MStatus &  status)
inline

The copy constructor of the class.

Initialize a new MStatus object with the values from another MStatus object.

Parameters
[in]statusThe target MStatus object.

Member Function Documentation

MStatus & operator= ( const MStatus &  rhs)
inline

The copy operator of the class.

Parameters
[in]rhsThe MStatus object to copy from.
Returns
A reference to the MStatus object that has been initialized.
bool operator== ( const MStatus &  rhs) const
inline

The equivalence operator that takes another MStatus object.

Parameters
[in]rhsA reference to the target object.
Returns
  • true the two MStatus objects are equal.
  • false the two MStatus objects are not equal.
bool operator== ( const MStatusCode  rhs) const
inline

The equivalence operator that takes a MStatus::MStatusCode.

Parameters
[in]rhsa MStatus::MStatusCode, e.g. MS::kSuccess.
Returns
  • true the object has the given detailed status code.
  • false the object does not have the given detailed status code.
bool operator!= ( const MStatus &  rhs) const
inline

The not equal operator for MStatus.

Parameters
[in]rhsa reference to the target object for comparison.
Returns
  • true the two MStatus objects are not equal.
  • false the two MStatus objects are equal.
bool operator!= ( const MStatusCode  rhs) const
inline

The not equal operator that takes a MStatus::MStatusCode.

Parameters
[in]rhsa MStatus::MStatusCode, e.g. MS::kSuccess.
Returns
  • true the object does not have the given detailed status code.
  • false the object has the given detailed status code.
bool error ( ) const
inline

Determines whether there is an error.

Returns
  • true an error has occured.
  • false the operation was successful
Examples:
dagMessageCmd/dagMessageCmd.cpp, geometrySurfaceConstraint/geometrySurfaceConstraint.cpp, and nodeCreatedCBCmd/nodeCreatedCBCmd.cpp.
void clear ( )
inline

Clear error codes from the MStatus instance.

After this call, it will behave as if it contained MS::kSuccess.

MStatus::MStatusCode statusCode ( ) const
inline

Retrieve the type of error that occurred, as specified in the MStatusCode enumeration.

Returns

void pAPIerror ( const char *  file,
int  line 
) const

This method prints the API error string to the standard error stream.

Parameters
[in]fileFilename where the error occured __FILE__.
[in]lineLine number of the error __LINE__.
void perror ( const MString &  preString) const

The second version of the perror() method.

This method takes a reference to a MString as the parameter. It prints the error string preceded by the string supplied by the user to the standard error stream.

Parameters
[in]preStringa reference to a MString object that contains the prefix string.
void set ( bool  status,
unsigned char  statusCode,
unsigned char  internalStatusCode 
)
inline

Internal use only.

The method is called interally by Maya to construct MStatus objects.

It should not be called from plugins.

Parameters
[in]statustrue or false
[in]statusCodean element of MStatusCode
[in]internalStatusCodean internal Maya error code
Examples:
AbcBullet/AttributesWriter.cpp, AbcExport/AttributesWriter.cpp, AbcExport/MayaMeshWriter.cpp, cvColorNode/cvColorNode.cpp, viewDX11DeviceAccess/viewDX11DeviceAccess.cpp, viewRenderOverride/viewRenderOverride.cpp, and weightListNode/weightListNode.cpp.
void setSuccess ( )
inline

The method is called interally by Maya to set the status as success.

It should not be called from plugins.

operator bool ( ) const
inline

NO SCRIPT SUPPORT.

The conversion operator that converts a MStatus object to bool.

The result it returns will be true if the MStatus does not contain an error, and false if it does.

OPENMAYA_EXPORT std::ostream& operator<< ( std::ostream &  out,
MStatus &  status 
)
friend

NO SCRIPT SUPPORT.

This method outputs the detailed status code as well as the internal error description. The format of the output is "(errNumber): errorDescriptiveText".

Parameters
[in]outThe ostream object that the output should be directed to.
[in]statusThe MStatus object.
Returns
A reference to the ostream object.
