Detailed Description

Manipulate strings.

The MString class implements a string class, and is used to pass all string arguments to Maya API methods.

The MString class supports localized strings. Use of the MString class to store and manipulate strings largely insulates the code from locale-dependent processing. Code that uses the class and its methods will in most cases operate seamlessly in both multibyte and single-byte environments. Knowledge of the underlying string storage mechanism or encoding is not required to use the class, and assumptions about this should not be made by the calling code.

Unless otherwise indicated, MString methods accepting or returning string contents via character buffers (char *) use the convention that the string contents are in the locale's native multibyte encoding. Methods which explicitly support other common encodings and representations such as UTF-8 and wchar_t are also provided. Code that manipulates string contents should use the multibyte-safe methods provided by the class. Refer to documentation on individual MString methods for more information.

Returns: The value of the current string converted to a double.

MString expandEnvironmentVariablesAndTilde ( MStatus * ReturnStatus = NULL ) const

Returns a new string constructed by duplicating the current string with all environment variables expanded (and on UNIX, tilde characaters ("~") are also expanded.

Environment variables may be of the form $ENV_VAR or ${ENV_VAR}. On Windows, ENV_VAR, ENV_VAR% and %{ENV_VAR}% are also accepted. If no environment variable in the system matches that given, the unexpanded variable is copied verbatim into the result string. On UNIX, any tilde characters ("~") will also be expanded according to the standard UNIX convention. If the user name associated with a tilde is undefined, the tilde and name which follows it are copied verbatim into the result string. Notes (1) when any error occurs, processing continues such that all subsequent environment variable and tilde occurences are processed and the resulting string can be displayed to the user to help diagnose the undefined entities (2) escape sequences using backslash characters are not supported.

Parameters

[out] ReturnStatus Status code

Returns: A new string containing the value of the original string with environment variable (and tilde characters on UNIX) which were defined expanded. All undefined environment variables and tildes are copied into the result string unexpanded.

Status Codes:

MS::kSuccess All expansions succeeded.
MS::kNotFound One or more expansion failed.

Examples:: dx11Shader/dx11ShaderCompileHelper.cpp, glslShader/GLSLShader.cpp, and gpuCache/gpuCacheConfig.cpp.

MString expandFilePath ( MStatus * ReturnStatus = NULL ) const

Returns a new string constructed by duplicating the current string with all environment variables expanded (and on UNIX, tilde characaters ("~") are also expanded.

Environment variables may be of the form $ENV_VAR or ${ENV_VAR}. On Windows, ENV_VAR, ENV_VAR% and %{ENV_VAR}% are also accepted. If no environment variable in the system matches that given, the unexpanded variable is copied verbatim into the result string. On UNIX, any tilde characters ("~") will also be expanded according to the standard UNIX convention. If the user name associated with a tilde is undefined, the tilde and name which follows it are copied verbatim into the result string. Notes (1) when any error occurs, processing continues such that all subsequent environment variable and tilde occurences are processed and the resulting string can be displayed to the user to help diagnose the undefined entities (2) escape sequences using backslash characters are not supported.

This does some file-path specific expansion. So if we have an invalid sequence like $A;;$B or $A::$B (on Mac/Linux), it will be collapsed to $A;$B or $A:$B respectively, then expanded.

We also do file-path specific nested environment variable expansion. So if you have $A/foo, and $A = "A;a", this will result in, A/foo;a/foo instead of A;a/foo. If you want A;a/foo, use MString::expandEnvironmentVariablesAndTilde

Parameters

[out] ReturnStatus Status code

Returns: A new string containing the value of the original string with environment variable (and tilde characters on UNIX) which were defined expanded. All undefined environment variables and tildes are copied into the result string unexpanded.

Status Codes:

MS::kSuccess All expansions succeeded.
MS::kNotFound One or more expansion failed.

MStatus format	(	const MString &	fmt,
		const MStringArray &	args
	)

Format the string value using a format specifier and an array of positional arguments.

A maximum of 10 arguments may be specified in the array passed. The number of arguments must match exactly the number of arguments expected by the format statement.

All arguments are passed as MStrings (any numeric data for example must already be formatted by the caller into an MString).

Format specifiers determine the relative position and ordering of arguments in the string using specifiers of the form: ^1s ^2s ^3s etc. See also the mel format command.

Parameters

[in]	fmt	format string (up to 10 positional argument specifiers)
[in]	args	array of arguments to be positioned in the format string

Returns: MS::kSuccess for success, otherwise MS::kFailure

Examples:: AbcBullet/AbcBullet.cpp, AbcBullet/MayaTransformCollectionWriter.cpp, AbcBullet/MayaTransformWriter.cpp, AbcExport/AbcExport.cpp, AbcExport/MayaMeshWriter.cpp, AbcImport/AbcImport.cpp, AbcImport/AlembicImportFileTranslator.cpp, AbcImport/CreateSceneHelper.cpp, animImportExport/animFileUtils.cpp, atomImportExport/atomFileUtils.cpp, autoLoader/moduleLogic.cpp, blast2Cmd/blast2Cmd.cpp, closestPointOnCurve/closestPointOnCurveCmd.cpp, depthShader/depthShader.cpp, dx11Shader/dx11Shader.cpp, dx11Shader/dx11ShaderStrings.cpp, glslShader/GLSLShaderStrings.cpp, gpuCache/CacheWriterAlembic.cpp, gpuCache/gpuCacheCmd.cpp, gpuCache/gpuCacheShapeNode.cpp, gpuCache/gpuCacheUtil.h, hwApiTextureTest/hwApiTextureTest.cpp, hwApiTextureTest/hwApiTextureTestStrings.cpp, MetadataSample/createMetadataCmd.cpp, MetadataSample/exportMetadataCmd.cpp, MetadataSample/importMetadataCmd.cpp, MetadataSample/metadataBase.cpp, nodeInfoCmd/nodeInfoCmd.cpp, sceneAssembly/adskSceneMetadataCmd.cpp, sceneAssembly/assemblyDefinition.cpp, sceneAssembly/assemblyReference.cpp, and sceneAssembly/sceneAssemblyPluginMain.cpp.

MStatus format	(	const MString &	fmt,
		const MString &	arg1 = `MString::argUnused`,
		const MString &	arg2 = `MString::argUnused`,
		const MString &	arg3 = `MString::argUnused`,
		const MString &	arg4 = `MString::argUnused`,
		const MString &	arg5 = `MString::argUnused`,

		const MString &	arg8 = `MString::argUnused`,
		const MString &	arg9 = `MString::argUnused`,
		const MString &	arg10 = `MString::argUnused`
	)

Format the string value using a format specifier and positional arguments.

A maximum of 10 argument strings may be passed in the argument list. This routine accepts a variable number of arguments in the argument list. Unused arguments should not be passed. (i.e. if 3 arguments are required by the format statement, exactly 3 arguments should be passed when calling MString::format).

All arguments are passed as MStrings (any numeric data for example must already be converted by the caller to an MString).

Format specifiers determine the relative position and ordering of arguments in the string using specifiers of the form: ^1s ^2s ^3s etc. See also the mel format command for more information.

Parameters

[in]	fmt	format string (up to 10 positional arguments)
[in]	arg1	argument to be positioned in the format string
[in]	arg2	argument to be positioned in the format string
[in]	arg3	argument to be positioned in the format string
[in]	arg4	argument to be positioned in the format string
[in]	arg5	argument to be positioned in the format string
[in]	arg6	argument to be positioned in the format string
[in]	arg7	argument to be positioned in the format string
[in]	arg8	argument to be positioned in the format string
[in]	arg9	argument to be positioned in the format string
[in]	arg10	argument to be positioned in the format string

Returns: MS::kSuccess for success, otherwise MS::kFailure
