MTimeArray Class Reference

#include <MTimeArray.h>

Class Description

Array of MTime data type.

This class implements an array of MTimes. 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.

Constructor & Destructor Documentation

OPENMAYA_MAJOR_NAMESPACE_OPEN MTimeArray ( )

Default Constructor.

The instance is set to contain no elements.

MTimeArray ( const MTimeArray other)

Copy Constructor.

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

NO SCRIPT SUPPORT.

Create a new array of MTimes and initialize it with the given MTime elements.

Parameters
[in]srcan array of MTimes
[in]countthe number of elements in the src array
MTimeArray ( unsigned int  initialSize,
const MTime initialValue 
)

Create a new array of times 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 MTime & 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 desired element
Returns
A reference to the indicated element
MStatus set ( const MTime element,
unsigned int  index 
)

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

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
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]indexindex of the element to be removed
Returns
MS::kSuccess if the remove was successful and MS::kFailure otherwise
MStatus insert ( const MTime 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
MS::kSuccess if the insert was successful and MS::kFailure otherwise
MStatus append ( const MTime 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
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.

Returns
MS::kSuccess the operation is successful 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.
MTime & 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
MStatus get ( MTime  array[]) const

NO SCRIPT SUPPORT.

Copy the elements of the array into the given array of MTimes.

No checking is done to ensure that the destination array of MTimes 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
MTimeArray & operator= ( const MTimeArray other)

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

Parameters
[in]otherthe array being copied
Returns
A reference to this array
MStatus copy ( const MTimeArray 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
const char * className ( )
static

Returns the name of this class.

Returns
The name of this class.
