MFnUInt64ArrayData Class Reference

#include <MFnUInt64ArrayData.h>

Class Description

MUint64 array function set for dependency node data.

MFnUInt64ArrayData allows the creation and manipulation of MUint64Array data objects for use in the dependency graph.

If a user written dependency node either accepts or produces MUint64Arrays, 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 kUInt64Array 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 MFnUInt64ArrayData.

Constructor & Destructor Documentation

MFnUInt64ArrayData ( 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
MFnUInt64ArrayData ( 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::kUInt64ArrayData.

Reimplemented from MFnData.

OPENMAYA_MAJOR_NAMESPACE_OPEN const char * className ( ) const
protectedvirtual

Class name.

Return the class name : "MFnUInt64ArrayData".

Reimplemented from MFnData.

unsigned int length ( MStatus ReturnStatus = NULL) const

Return the number of MUint64s in the instance.

Parameters
[out]ReturnStatuskFailure if the instance is not attached to an MObject, and kSuccess otherwise.
Returns
The number of MUint64s in the instance
MStatus set ( MUint64  element,
unsigned int  index 
)

Set the element at the specified index of the 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 MUint64 to set
Returns
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject
MStatus copyTo ( MUint64Array dest) const

Copy all the MUint64s in the instance into the given MUint64Array.

Parameters
[out]destthe MUint64Array to populate
Returns
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject
MStatus set ( const MUint64Array array)

Set the instance to contain the MUint64s defined in the given MUint64Array.

Parameters
[in]arraythe MUint64Array containing the data to set into this instance
Returns
  • kSuccess operation successful
  • kFailure instance is not attached to an MObject
MUint64Array array ( MStatus ReturnStatus = NULL)

Return an MUint64Array containing the MUint64 array currently operated upon by the function set.

The MUint64Array 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 MUint64Array held in this instance
MObject create ( MStatus ReturnStatus = NULL)

Create a new MObject, attach it to this instance, and initialize it to be empty.

Parameters
[out]ReturnStatuskSuccess
Returns
The newly created MObject
MObject create ( const MUint64Array arr,
MStatus ReturnStatus = NULL 
)

Create a new MObject, attach it to this instance, and initialize it to contain the data from the given MUint64Array.

Parameters
[in]arrthe data to use when initializing this instance
[out]ReturnStatuskSuccess
Returns
The newly created MObject
MUint64 operator[] ( unsigned int  index) const

NO SCRIPT SUPPORT.

Extract the indicated MUint64 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 MUint64 containing zero.

Parameters
[in]indexthe index of the MUint64 to extract
Returns
The indicated MUint64
MUint64 & operator[] ( unsigned int  index)

Extract the indicated MUint64 from the instance.

by the function set. The MUint64 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 MUint64 containing zero.

Parameters
[in]indexthe index of the MUint64 to extract
Returns
The indicated MUint64
