## Detailed Description

Base class for user commands.

This is the proxy class for creating MEL commands through the API.

Each command is derived from this one, and must have a doIt method, and optionally undoIt, and redoIt methods.

The doIt method should collect whatever information is required to do the task, and store it in local class data. It should finally call redoIt to make the command happen. The redoIt method should do the actual work, using only the local class data. The undoIt method should undo the actual work, again using only the local class data.

Maya contains support for infinite levels of undo. If a command written in a plug-in changes the state of anything in Maya, it should implement undoIt and redoIt methods. As well, if the doIt method returns successfully, Maya will call the method's isUndoable method immediately afterwards. If that method returns true, the instance of this class is retained and passed to Maya's undo manager so that the undoIt and redoIt methods can be called when appropriate. If isUndoable returns false, the command instance is destroyed right away.

So, for example, if a command supports both query and edit modes, in query mode the command should set a flag so that the isUndoable method returns false to prevent that command instance from being retained by the undo manager. In edit mode, where the state of Maya is changed, isUndoable should return true to enable undo and redo.

bool isUndoable | ( |  | ) | const`[virtual]`

Search for all occurrences

This method is used to specify whether or not the command is undoable.

In the base class, it always returns false. If you are writing a command that might be eligible for undo, you should override this method.

After Maya executes the command's doIt method, it will call isUndoable. If isUndoable returns true, Maya will retain the instance of the class and pass it to Maya's undo manager so that the undoIt and redoIt methods can be called when appropriate. If isUndoable returns false, the command instance will be immediately destroyed.

So, for example, if a command supports both query and edit modes, in query mode the command should set a flag so that the isUndoable method returns false to prevent that command instance from being retained by the undo manager. In edit mode, where the state of Maya is changed, isUndoable should return true to enable undo and redo.

Returns:
  - true This command is undoable
  - false This command is not undoable (default)

Reimplemented in MTemplateCommand< CommandClass, CommandName, CommandSyntax >, and MTemplateCommand< CommandClass, CommandName, MTemplateCreateNodeCommand_newSyntax >.

Examples:
  blindComplexDataCmd.cpp, blindDoubleDataCmd.cpp, cgfxShaderCmd.h, closestPointCmd.cpp, closestPointOnCurveCmd.h, closestPointOnNurbsSurfaceCmd.h, clothPaintAttrCmd.h, convertBumpCmd.cpp, convertEdgesToFacesCmd.cpp, convertVerticesToEdgesCmd.cpp, convertVerticesToFacesCmd.cpp, createClipCmd.cpp, cvPosCmd.cpp, dagPoseInfoCmd.cpp, exportJointClusterDataCmd.cpp, exportSkinClusterDataCmd.cpp, fxManagerCmd.h, helix2Cmd.cpp, helixTool.cpp, iffInfoCmd.cpp, iffPixelCmd.cpp, intersectCmd.cpp, intersectOnNurbsSurfaceCmd.h, meshRemapCmd.h, meshReorderCmd.h, moveNumericTool.cpp, moveTool.cpp, pointOnMeshCmd.h, polyPrimitiveCmd.cpp, referenceQueryCmd.cpp, and zoomCameraCmd.cpp.

bool hasSyntax | ( |  | ) | const`[virtual]`

Search for all occurrences

This method specifies whether or not the command has a syntax object.

Returns:
  Boolean value: true if this command uses syntax objects, false otherwise.

Examples:
  fxManagerCmd.h, and geometryCacheConverter.cpp.

MSyntax syntax | ( |  | ) | const

Search for all occurrences

This method is intended to be used in an MArgDataBase or MArgParser contructor when the plugin command's syntax is being initialized.

The user should declare and define a syntax contstructing method that must be registered with Maya by passing the function pointer as a parameter in MFnPlugin::registerCommand(). The result is that when MPxCommand::syntax() is called it returns the syntax object that the user has created in the custom syntax constructing method that was registered. To avoid conflicts it is important that the user's custom syntax defining method be given a name other than "syntax." It can have any other name as long as it corresponds with the function pointer used to register the method with Maya.

Returns:
  The syntax object

bool isHistoryOn | ( |  | ) | const

Search for all occurrences

Returns whether history is on.

Returns:
  Boolean value: true if history is on, false otherwise.

Examples:
  fxManagerCmd.h.

Returns:
  The command string for this command object

Examples:
  fxManagerCmd.h.

MStatus setHistoryOn | ( | bool | state | ) |

Search for all occurrences

This method specifies if history for this command is on.

Parameters:

Examples:
  fxManagerCmd.h.
