MFloatArray Class Reference
#include <MFloatArray.h>
Array of floats data type.
This class implements an array of floats. Common convenience functions are available, and the implementation is compatible with the internal Maya implementation so that it can be passed efficiently between plugins and internal maya data structures.
Methods that query the array are threadsafe. Writing to different array elements at the same time with the set() method is threadsafe. Methods that modify the array length, namely append() , insert() , remove() and setLength() are not threadsafe.

Default constructor.
The instance is set to contain no elements.
Copy Constructor.
Parameters
[in] other the array with which to initialize this instance
Create a new array of floats and initialize it with the given float elements.
Parameters
[in] src a C++ array of floats
[in] count the number of elements in the src array
Create a new array of floats and initialize it with the given double elements.
Parameters
[in] src a C++ array of floats
[in] count the number of elements in the src array
MFloatArray
(
unsigned int
initialSize ,
float
initialValue = 0
)
Create a new array of floats of a specified size and initialize all the elements with the given initial value.
Parameters
[in] initialSize the initial size of the array
[in] initialValue the initial value of each element
Assignment operator copies all of the elements of the other array into this one.
Parameters
[in] other the array being copied
Returns A reference to this array
MStatus set
(
float
element ,
unsigned int
index
)
Sets the value of the indicated element to the indicated float 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] element the new value for the indicated element
[in] index the 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
(
double
element ,
unsigned int
index
)
Sets the value of the indicated element to the indicated double 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] element the new value for the indicated element
[in] index the 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] length the new size of the array
unsigned int length
(
)
const
Returns the number of elements in the instance.
Returns The number of elements in the instance

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] index index of the element to be removed
Returns MS::kSuccess if the remove was successful and MS::kFailure otherwise
MStatus insert
(
float
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] element the new value to insert into the array
[in] index the index of the element to set to the the new value
Returns MS::kSuccess if the insert was successful and MS::kFailure otherwise
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] element the value for the new last element
Returns MS::kSuccess if the append was successful and MS::kFailure otherwise
Copy the contents of the source array to this array.
Parameters
[in] source array to copy from
Returns MS::kSuccess if the copy was successful and MS::kFailure otherwise
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
Copy the elements of the array into the given C++ array of floats.
No checking is done to ensure that the destination C++ array of floats is large enough to hold all the elements of the instance.
Parameters
[out] array the array to populate
Returns MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise
MStatus get
(
double
array [])
const
Copy the elements of the array into the given C++ array of doubles.
No checking is done to ensure that the destination C++ array of doubles is large enough to hold all the elements of the instance.
Parameters
[out] array the 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] newIncrement the new increment
unsigned int sizeIncrement
(
)
const
Return the size by which the array will be expanded whenever expansion is necessary.
Returns The size increment.
float operator[]
(
unsigned int
index )
const
NO SCRIPT SUPPORT.
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] index the index of the element whose value is to be returned
Returns The value of the indicated element.
float & 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] index the 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.
