Documentation

Description

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.

Functions

MFnIntArrayData:: MFnIntArrayData ()

Description

Default class constructor. The function set is not attached to an MObject.

MFnIntArrayData:: MFnIntArrayData ( MObject & object, MStatus * ReturnStatus )

Description

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

Arguments

• object the MObject to attach the function set to
• ReturnStatus the return status
  • 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:: MFnIntArrayData ( const MObject & object, MStatus * ReturnStatus )

Description

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

Arguments

• object the const MObject to attach the function set to
• ReturnStatus the return status
  • 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:: ~MFnIntArrayData ()

Description

The class destructor.

MFn::Type MFnIntArrayData:: type () const

Description

Return the type of this function set.

Return Value

• the constant MFn::kIntArrayData

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

Description

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.

Arguments

• index the index of the integer to extract

Return Value

• the indicated integer

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

Description

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.

Arguments

• index the index of the integer to extract

Return Value

• the indicated integer

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

Description

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.

Arguments

• element the element
• index the index of the integer to extract

Return Value

• kSuccess operation successful
• kFailure instance is not attached to an MObject

unsigned int MFnIntArrayData:: length ( MStatus * ReturnStatus ) const

Description

Return the number of integers in the instance.

Arguments

• ReturnStatus kFailure if the instance is not attached to an MObject, and kSuccess otherwise.

Return Value

• the number of integers in the instance

MStatus MFnIntArrayData:: copyTo ( MIntArray & dest ) const

Description

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

Arguments

• dest the MIntArray to populate

Return Value

• kSuccess operation successful
• kFailure instance is not attached to an MObject

MStatus MFnIntArrayData:: set ( const MIntArray & array )

Description

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

Arguments

• array the MIntArray containing the data to set into this instance

Return Value

• kSuccess operation successful
• kFailure instance is not attached to an MObject

MIntArray MFnIntArrayData:: array ( MStatus * ReturnStatus )

Description

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.

Arguments

• ReturnStatus kFailure if the instance is not attached to an MObject, and kSuccess otherwise.

Return Value

• a copy of the MIntArray held in this instance

MObject MFnIntArrayData:: create ( const MIntArray & arr, MStatus * ReturnStatus )

Description

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

Arguments

• arr the data to use when initializing this instance
• ReturnStatus kSuccess

Return Value

• the newly created MObject

MObject MFnIntArrayData:: create ( MStatus * ReturnStatus )

Description

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

Arguments

• ReturnStatus kSuccess

Return Value

• the newly created MObject
