#include <MTimeArray.h>

List of all members.


Detailed 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

MTimeArray::MTimeArray (  ) 

Default Constructor. The instance is set to contain no elements.

MTimeArray::MTimeArray ( const MTimeArray other  ) 

Copy Constructor.

Parameters:
[in]  other  the array with which to initialize this instance

MTimeArray::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]  src  an array of MTimes
[in]  count  the number of elements in the src array

MTimeArray::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]  initialSize  the initial size of the array
[in]  initialValue  the initial value of each element

MTimeArray::~MTimeArray (  ) 

Class Destructor.


Member Function Documentation

const MTime & MTimeArray::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]  index  the index of the desired element
Returns:
A reference to the indicated element

MStatus MTimeArray::set ( const MTime element,
unsigned int  index  
)

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

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 MTimeArray::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 MTimeArray::length (  )  const

Returns the number of elements in the instance.

Returns:
The number of elements in the instance

MStatus MTimeArray::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 MTimeArray::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]  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

MStatus MTimeArray::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]  element  the value for the new last element
Returns:
MS::kSuccess if the append was successful and MS::kFailure otherwise

MStatus MTimeArray::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 MTimeArray::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 MTimeArray::sizeIncrement (  )  const

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

Returns:
true if the array argument is a non-zero pointer and false otherwise

MTime & MTimeArray::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

MStatus MTimeArray::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]  array  the array to populate
Returns:
MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise

OPENMAYA_EXPORT std::ostream& operator<< ( std::ostream &  os,
const MTimeArray array  
) [friend]

NO SCRIPT SUPPORT.

Print the contents of the given MTimeArray on the given ostream. The format used is [time, time, time, ... time].

Parameters:
[in]  os  the ostream to print to
[in]  array  the MTimeArray whose value is to be printed
Returns:
The ostream reference, s, provided as the first parameter.
