MFnIntArrayData Class Reference

#include <MFnIntArrayData.h>

Class 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.

Constructor & Destructor Documentation

MFnIntArrayData ( MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

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

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe 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
MFnIntArrayData ( const MObject object,
MStatus ReturnStatus = NULL 
)

Constructor.

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

Parameters
[in]objectThe MObject to attach the function set to
[out]ReturnStatusthe 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

Member Function Documentation

MFn::Type type ( ) const
virtual

Function set type.

Return the class type : MFn::kIntArrayData.

Reimplemented from MFnData.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( ) const
protectedvirtual

Class name.

Return the class name : "MFnIntArrayData".

Reimplemented from MFnData.

unsigned int length ( MStatus ReturnStatus = NULL) const

Return the number of integers in the instance.

Parameters
[out]ReturnStatuskFailure if the instance is not attached to an MObject, and kSuccess otherwise.
Returns
The number of integers in the instance
+ Examples:
int 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]indexthe index of the integer to extract
Returns
The indicated integer
MStatus 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]elementthe element
[in]indexthe index of the integer to extract
Returns
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject
MStatus copyTo ( MIntArray dest) const

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

Parameters
[out]destthe MIntArray to populate
Returns
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject
MStatus set ( const MIntArray array)

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

Parameters
[in]arraythe MIntArray containing the data to set into this instance
Returns
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject
MIntArray 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]ReturnStatuskFailure if the instance is not attached to an MObject, and kSuccess otherwise.
Returns
A copy of the MIntArray held in this instance
MObject create ( MStatus ReturnStatus = NULL)

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

Parameters
[out]ReturnStatuskSuccess
Returns
The newly created MObject
+ Examples:
MObject 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]arrthe data to use when initializing this instance
[out]ReturnStatuskSuccess
Returns
The newly created MObject
int & 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]indexthe index of the integer to extract
