## Detailed Description

Array of MUint64 data type.

This class implements an array of MUint64s. 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.

`#include <MUint64Array.h>`

## Constructor & Destructor Documentation

MUint64Array | ( |  | ) |

Default constructor.

The instance is set to contain no elements.

MUint64Array | ( | const MUint64Array & | other | ) |

Copy Constructor.

Parameters:

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

MUint64Array | ( | const MUint64 | src[],
|  | unsigned int | count
| ) |  |

Create a new array of MUint64 and initialize it with the given MUint64 elements.

Parameters:

  [in] | src | a C++ array of MUint64
  [in] | count | the number of elements in the src array

MUint64Array | ( | unsigned int | initialSize,
|  | MUint64 | initialValue = `0`
| ) |  |

Create a new array of MUint64 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

## Member Function Documentation

MUint64Array & operator= | ( | const MUint64Array & | 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 MFnMUint64ArrayData::array), then this array will also become a reference rather than doing a full copy.

Parameters:

  [in] | other | the array being copied

Returns:
  A reference to this array

MStatus set | ( | MUint64 | element,
|  | unsigned int | index
| ) |  |

Search for all occurrences

Sets the value of the indicated element to the indicated MUint64 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 | ) |

Search for all occurrences

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

Search for all occurrences

Returns the number of elements in the instance.

Returns:
  The number of elements in the instance

MStatus remove | ( | unsigned int | index | ) |

Search for all occurrences

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 | ( | MUint64 | element,
|  | unsigned int | index
| ) |  |

Search for all occurrences

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 append | ( | MUint64 | element | ) |

Search for all occurrences

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 copy | ( | const MUint64Array & | source | ) |

Search for all occurrences

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

MStatus clear | ( |  | ) |

Search for all occurrences

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

MStatus get | ( | MUint64 | array[] | ) | const

Search for all occurrences

Copy the elements of the array into the given C++ array of MUint64s.

No checking is done to ensure that the destination C++ array of MUint64s 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 | ) |

Search for all occurrences

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

Parameters:

  [in] | newIncrement | the new increment

unsigned int sizeIncrement | ( |  | ) | const

Search for all occurrences

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

Returns:
  The size increment.

MUint64 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.

MUint64 & 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]`

Search for all occurrences

Returns the name of this class.

Returns:
  The name of this class.

OPENMAYA_EXPORT std::ostream& operator<< | ( | std::ostream & | os,
|  | const MUint64Array & | array
| ) |  | `[friend]`

NO SCRIPT SUPPORT.

The format used is [14:22, 43:22, ]. The first number is the high 32 bits; the second number is the low 32 bits.

Parameters:

  [in] | os | the ostream to print to
  [in] | array | the MUint64Array whose value is to be printed

Returns:
  The ostream reference, s, provided as the first parameter.
