Detailed Description
Function set for multiple arrays of attributes for dependency node
data.
MFnArrayAttrsData allows the creation and manipulation of
multiple arrays of attributes as a data object over a single
connection for use as dependency graph data.
If a user written dependency node either accepts or produces
MFnArrayAttrsData, then this class is used to extract or create
the data that comes from or goes to other dependency graph nodes.
The MDataHandle::type
method will return kDynArrayAttrsData when data of this type is
present. To access it, the MDataHandle::data()
method is used to get an MObject for the data and this should then
be used to initialize an instance of
MFnArrayAttrsData.
NOTE: these data attributes are not storable.

Invalid value. |
kVectorArray |
use
vectorArray() method to extract the attribute array. |
kDoubleArray |
use
doubleArray() method to extract the attribute array. |
kIntArray |
use
intArray() method to extract the attribute array. |

) |
|
Clear the contents of all of the arrays.
- Returns:
-
- kSuccess operation successful
- kFailure MS::kFailure if the instance is
not attached to an MObject
unsigned int MFnArrayAttrsData::count |
( |
|
) |
const |
Returns the number of attribute arrays.
- Returns:
- The number or arrays
Returns a list of names for the attribute arrays.
- Parameters:
-
[out] |
ReturnStatus |
Status code. |
- Returns:
- A list of all the names of all the arrays stored in the
data.
Check if the attribute array related to the given name has been
created. If the named array exists return true and the array data
type.
- Parameters:
-
[in] |
name |
the name of the array to check |
[out] |
arrayType |
the type of the array |
[out] |
ReturnStatus |
kFailure if the instance is not attached to an MObject, and kSuccess
otherwise. |
- Returns:
- True if the array exists and false otherwise.
Return an MVectorArray containing the
vector array currently operated upon by the function set. The
MVectorArray returned by this
method is editable, so any changes to the return instance also
affects the MObject
operated upon by this function set. If the array did not exist it
will be created.
- Parameters:
-
[in] |
name |
the name of the array to edit or create. |
[out] |
ReturnStatus |
kFailure if the instance is not attached to an MObject, and kSuccess
otherwise. |
- Returns:
- A copy of the MVectorArray held in this
instance
Return an MDoubleArray containing the
double array currently operated upon by the function set. The
MDoubleArray returned by this
method is editable, so any changes to the return instance also
affects the MObject
operated upon by this function set. If the array did not exist it
will be created.
- Parameters:
-
[in] |
name |

[out] |
ReturnStatus |
kFailure if the instance is not attached to an MObject, and kSuccess
otherwise. |
- Returns:
- A copy of the MDoubleArray held in this
instance
Return an MIntArray containing the int
array currently operated upon by the function set. The MIntArray returned by this
