Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MVectorArray ( )

Default constructor.

The instance is set to contain no elements.

MVectorArray ( const MVectorArray other)

Copy Constructor.

Parameters
[in]otherthe array with which to initialize this instance
MVectorArray ( const MVector  src[],
unsigned int  count 
)

NO SCRIPT SUPPORT.

Parameters
[in]srcan array of MVectors
[in]countthe number of elements in the src array
MVectorArray ( const double  src[][3],
unsigned int  count 
)

Create a new array of MVectors and initialize it with the given double array elements.

Parameters
[in]srcan array of double arrays of length 3
[in]countthe number of elements in the src array
MVectorArray ( const float  src[][3],
unsigned int  count 
)

Create a new array of MVectors and initialize it with the given float array elements.

Parameters
[in]srcan array of float arrays of length 3
[in]countthe number of elements in the src array
MVectorArray ( unsigned int  initialSize,
const MVector initialValue = MVector::zero 
)

Create a new array of MVectors of a specified size and initialize all the elements with the given initial value.

Parameters
[in]initialSizethe initial size of the array
[in]initialValuethe initial value of each element

Member Function Documentation

const MVector & operator[] ( unsigned int  index) const

Index operator.

Returns the value of the element at the given index. No range checking is done - valid indices are 0 to length()-1.

Parameters
[in]indexthe index of the element whose value is to be returned
Returns
The value of the indicated element.
MVectorArray & operator= ( const MVectorArray other)

Assignment operator copies all of the elements of the other array into this one.

If the other array was returned as a reference to internal data (eg MFnVectorArrayData::array), then this array will also become a reference rather than doing a full copy.

Parameters
[in]otherthe array being copied
Returns
A reference to this array
MStatus set ( const MVector element,
unsigned int  index 
)

Sets the value of the indicated element to the indicated MVector value.

NOTE: This method does not grow the array if the index is out of bounds. Only a valid index should be used.

Parameters
[in]elementthe new value for the indicated element
[in]indexthe index of the element that is to be set to the the new value
Returns
MS::kSuccess if the value was set successfully and MS::kFailure otherwise
+ Examples:
MStatus set ( double  element[3],
unsigned int  index 
)

Sets the value of the indicated element to the indicated double array value.

NOTE: This method does not grow the array if the index is out of bounds. Only a valid index should be used.

Parameters
[in]elementthe new value for the indicated element
[in]indexthe index of the element that is to be set to the the new value
Returns
MS::kSuccess if the value was set successfully and MS::kFailure otherwise
MStatus set ( float  element[3],
unsigned int  index 
)

Sets the value of the indicated element to the indicated float array value.

NOTE: This method does not grow the array if the index is out of bounds. Only a valid index should be used.

Parameters
[in]elementthe new value for the indicated element
[in]indexthe index of the element that is to be set to the the new value
Returns
MS::kSuccess if the value was set successfully and MS::kFailure otherwise
MStatus setLength ( unsigned int  length)

Set the length of the array.

This will grow and shrink the array as desired. Elements that are grown have uninitialized values, while those which are shrunk will lose the data contained in the deleted elements (ie. it will release the memory).

Parameters
[in]lengththe new size of the array
+ Examples:
MStatus remove ( unsigned int  index)

Remove the array element at the given index.

All array elements following the removed element are shifted toward the first element.

Parameters
[in]indexindex of the element to be removed
Returns
MS::kSuccess if the remove was successful and MS::kFailure otherwise
MStatus insert ( const MVector element,
unsigned int  index 
)

Inserts a new value into the array at the given index.

The initial element at that index, and all following elements, are shifted towards the last. If the array cannot be expanded in size by 1 element, then the insert will fail and the existing array will remain unchanged.

Parameters
[in]elementthe new value to insert into the array
[in]indexthe index of the element to set to the the new value
Returns
true if the insert was successful and false otherwise
MStatus append ( const MVector element)

Adds a new element to the end of the array.

If the array cannot be expanded in size by 1 element, then the append will fail and the existing array will remain unchanged.

Parameters
[in]elementthe value for the new last element
Returns
MS::kSuccess if the append was successful and MS::kFailure otherwise
+ Examples:
MStatus copy ( const MVectorArray source)

Copy the contents of the source array to this array.

Parameters
[in]sourcearray to copy from
Returns
MS::kSuccess if the copy was successful and MS::kFailure otherwise
MStatus clear ( )

Clear the contents of the array.

After this operation the length method will return 0. This does not change the amount of memory allocated to the array, only the number of valid elements in it.

  • MS::kSuccess if the operation is successful and MS::kFailure otherwise
+ Examples:
MStatus get ( double  array[][3]) const

Copy the elements of the array into the given C++ array of double arrays.

No checking is done to ensure that the destination C++ array of double arrays is large enough to hold all the elements of the instance.

Parameters
[out]arraythe array to populate
Returns
MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise
MStatus get ( float  array[][3]) const

Copy the elements of the array into the given C++ array of float arrays.

No checking is done to ensure that the destination C++ array of floats arrays is large enough to hold all the elements of the instance.

Parameters
[out]arraythe array to populate
Returns
MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise
void setSizeIncrement ( unsigned int  newIncrement)

Set the size by which the array will be expanded whenever expansion is necessary.

Parameters
[in]newIncrementthe new increment
unsigned int sizeIncrement ( ) const

Return the size by which the array will be expanded whenever expansion is necessary.

Returns
The size increment.
MVector & operator[] ( unsigned int  index)

NO SCRIPT SUPPORT.

Index operator allowing assignment to an element of the array.

Returns a reference to the element at the given index. No range checking is done - valid indices are 0 to length()-1.

Parameters
[in]indexthe index of the desired element
Returns
A reference to the indicated element
const char * className ( )
static

Returns the name of this class.

Returns
The name of this class.
