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] status The 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] status The target MStatus object.

Member Function Documentation

MStatus & operator= ( const MStatus & rhs )

inline

The copy operator of the class.

Parameters

[in] rhs The 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] rhs A 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] rhs a 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] rhs a 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] rhs a 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.

Examples:: AbcImport/CreateSceneHelper.cpp, AbcImport/XformHelper.cpp, apiMeshShape/apiMeshGeom.h, apiMeshShape/apiMeshSubSceneOverride.cpp, captureViewRenderCmd/captureViewRenderCmd.cpp, cgFx/cgfxShaderCmd.cpp, cgFx/cgfxShaderNode.cpp, dx11Shader/dx11Shader.cpp, filteredAsciiFile/filteredAsciiFile.cpp, glslShader/GLSLShader.cpp, helix2Cmd/helix2Cmd.cpp, MayaPluginForSpreticle/spReticleLoc.cpp, meshOpCmd/polyModifierCmd.cpp, MetadataSample/metadataBase.cpp, sceneAssembly/assemblyDefinition.cpp, sceneAssembly/assemblyReference.cpp, splitUVCmd/polyModifierCmd.cpp, splitUVCmd/splitUVCmd.cpp, viewDX11DeviceAccess/viewDX11DeviceAccess.cpp, viewRenderOverride/viewRenderOverride.cpp, viewRenderOverridePointLightShadows/viewRenderOverridePointLightShadows.cpp, viewRenderOverrideShadows/viewRenderOverrideShadows.cpp, XmlGeometryCache/XmlGeometryCache.cpp, and XmlGeometryCacheDesc/XmlGeometryCacheDesc.cpp.

MStatus::MStatusCode statusCode ( ) const

inline

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

Returns: The type of error that occurred.

Examples:: dx11Shader/dx11Shader.cpp, glslShader/GLSLShader.cpp, scanDagCmd/scanDagCmd.cpp, and scanDagSyntax/scanDagSyntax.cpp.

MString errorString ( ) const

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

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

Parameters

[in]	file	Filename where the error occured __FILE__.
[in]	line	Line 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] preString a 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]	status	true or false
[in]	statusCode	an element of MStatusCode
[in]	internalStatusCode	an 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.

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]	out	The ostream object that the output should be directed to.
[in]	status	The MStatus object.

Returns: A reference to the ostream object.
