## Constructor & Destructor Documentation

MFnDoubleIndexedComponent | ( | MObject & | object,
|  | MStatus * | ReturnStatus = `NULL`
| ) |  |

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

  [in] | object | The MObject to attach the function set to
  [out] | ReturnStatus | the return status

Status Codes:
  - MS::kSuccess if the function set is successfully attached
  - MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnDoubleIndexedComponent | ( | const MObject & | object,
|  | MStatus * | ReturnStatus = `NULL`
| ) |  |

NO SCRIPT SUPPORT.

Class constructor that initializes the function set to the given MObject.

Constructor

Parameters:

  [in] | object | The MObject to attach the function set to
  [out] | ReturnStatus | the return status

Status Codes:
  - MS::kSuccess if the function set is successfully attached
  - MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

Search for all occurrences

Marks the component as complete (meaning all items are selected) and uses the argument to identify the total number of elements selected.

If the component should contain N element indices, then the range would be [0,N-1].

Also sets the complete state of the component to 'true' (i.e. setComplete(true)).

Parameters:

  [in] | maxU | the maximum number of U elements
  [in] | maxV | the maximum number of V elements

Returns:
  Status code

Status Codes:
  - MS::kSuccess the method was successful
  - MS::kFailure an object error has occurred

MStatus getCompleteData | ( | int & | maxU,
|  | int & | maxV
| ) |  | const

Search for all occurrences

Returns the number of elements for the complete component.

A complete component means that all elements are selected.

Parameters:

  [out] | maxU | storage for the maximum number of U elements
  [out] | maxV | storage for the maximum number of V elements

Returns:
  Status code

Status Codes:
  - MS::kSuccess the method was successful
  - MS::kFailure an object error has occurred
