Detailed Description

int array function set for dependency node data.

MFnIntArrayData allows the creation and manipulation of MIntArray data objects for use in the dependency graph.

If a user written dependency node either accepts or produces MIntArrays, 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 kIntArray 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 MFnIntArrayData.

Member Function Documentation

MFn::Type MFnIntArrayData::type (  )  const [virtual]

Function set type.

Return the class type : MFn::kIntArrayData

Reimplemented from MFnData.

const char * MFnIntArrayData::className (  )  const [protected, virtual]

Class name.

Return the class name : "MFnIntArrayData"

Reimplemented from MFnData.

unsigned int MFnIntArrayData::length ( MStatus ReturnStatus = NULL  )  const

Return the number of integers in the instance.

Parameters:
[out]  ReturnStatus  kFailure if the instance is not attached to an MObject, and kSuccess otherwise.
Returns:
The number of integers in the instance

int MFnIntArrayData::operator[] ( unsigned int  index  )  const

Extract the indicated integer 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 integer containing zero.

Parameters:
[in]  index  the index of the integer to extract
Returns:
The indicated integer

MStatus MFnIntArrayData::set ( int  element,
unsigned int  index  
)

Set the integer element at the specified index of this array.

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.

Parameters:
[in]  element  the element
[in]  index  the index of the integer to extract
Returns:
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject

MStatus MFnIntArrayData::copyTo ( MIntArray dest  )  const

Copy all the integers in the instance into the given MIntArray.

Parameters:
[out]  dest  the MIntArray to populate
Returns:
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject

MStatus MFnIntArrayData::set ( const MIntArray array  ) 

Set the instance to contain the integers defined in the given MIntArray.

Parameters:
[in]  array  the MIntArray containing the data to set into this instance
Returns:
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject

MIntArray MFnIntArrayData::array ( MStatus ReturnStatus = NULL  ) 

Return an MIntArray containing the integer array currently operated upon by the function set. The MIntArray returned by this method is editable, so any changes to the return instance also affects the MObject operated upon by this function set.

Parameters:
[out]  ReturnStatus  kFailure if the instance is not attached to an MObject, and kSuccess otherwise.
Returns:
A copy of the MIntArray held in this instance

MObject MFnIntArrayData::create ( MStatus ReturnStatus = NULL  ) 

Create a new MObject, attach it to this instance, and initialize it to contain no ints.

Parameters:
[out]  ReturnStatus  kSuccess
Returns:
The newly created MObject

MObject MFnIntArrayData::create ( const MIntArray arr,
MStatus ReturnStatus = NULL  
)

Create a new MObject, attach it to this instance, and initialize it to contain the data from the given MIntArray.

Parameters:
[in]  arr  the data to use when initializing this instance
[out]  ReturnStatus  kSuccess
Returns:
The newly created MObject

int & MFnIntArrayData::operator[] ( unsigned int  index  ) 

NO SCRIPT SUPPORT.

Extract the indicated integer from the instance. by the function set. The integer returned by this method is editable, so any changes to the return instance also affects 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 an integer containing zero.

Parameters:
[in]  index  the index of the integer to extract
Returns:
The indicated integer
