#include <MFnDoubleArrayData.h>
double array function set for dependency node data.
MFnDoubleArrayData allows the creation and manipulation of MDoubleArray data objects for use in the dependency graph.
If a user written dependency node either accepts or produces MDoubleArrays, 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 kDoubleArray 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 MFnDoubleArrayData.

unsigned int length | ( | MStatus * | ReturnStatus = NULL | ) | const |
Return the number of doubles in the instance.
[out] | ReturnStatus | kFailure if the instance is not attached to an MObject, and kSuccess otherwise. |
double operator[] | ( | unsigned int | index | ) | const |
Extract the indicated double from the const instance.
No checking is done by this class to ensure that the index is valid - use the length method to determine the size of the array. If the instance is not attached to an MObject, this method will return an double containing zero.
[in] | index | the index of the double to extract |
MStatus set | ( | double | element, |
unsigned int | index | ||
) |
Set the double array element at the specified index.
The index must be valid for the array.
[in] | element | the element to set at the specified index |
[in] | index | the index of the double to set |
MStatus copyTo | ( | MDoubleArray & | dest | ) | const |
Copy all the doubles in the instance into the given MDoubleArray.
[out] | dest | the MDoubleArray to populate |
MStatus set | ( | const MDoubleArray & | array | ) |
Set the instance to contain the doubles defined in the given MDoubleArray.
[in] | array | the MDoubleArray containing the data to set into this instance |
MDoubleArray array | ( | MStatus * | ReturnStatus = NULL | ) |
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.
[out] | ReturnStatus | kFailure if the instance is not attached to an MObject, and kSuccess otherwise. |
Create a new double array data object, initialize it to be empty, and attach it to this instance.
[out] | ReturnStatus | kSuccess |
MObject create | ( | const MDoubleArray & | arr, |
MStatus * | ReturnStatus = NULL |
||
) |
Create a new double array data object, initialize it to contain the data from the given MDoubleArray, and attach it to this instance.
[in] | arr | the data to use when initializing this instance |
[out] | ReturnStatus | kSuccess |
double & operator[] | ( | unsigned int | index | ) |
NO SCRIPT SUPPORT.
Extract the indicated double from the instance.
The double returned by this method is editable, so any changes to the return instance also affect the MObject operated upon by this function set.
No checking is done by this class to ensure that the index is valid - use the length method to determine the size of the array. If the instance is not attached to an MObject, this method will return a reference to a dummy value.
[in] | index | the index of the double to extract |
