Description

This class implements an array of MCallbackId. 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.

Functions

MCallbackIdArray:: MCallbackIdArray ()

Description

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

MCallbackIdArray:: MCallbackIdArray ( const MCallbackIdArray & other )

Description

Copy Constructor.

Arguments

• other the array with which to initialize this instance

MCallbackIdArray:: MCallbackIdArray ( const MCallbackId src[], unsigned int count )

Description

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

Arguments

• src a C++ array of MCallbackIds
• count the number of elements in the src array

MCallbackIdArray:: MCallbackIdArray ( unsigned int initialSize, MCallbackId initialValue )

Description

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

Arguments

• initialSize the initial size of the array
• initialValue the initial value of each element

MCallbackIdArray:: ~MCallbackIdArray ()

Description

The class destructor.

MCallbackId MCallbackIdArray:: operator[] ( unsigned int index ) const

Description

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

Arguments

• index the index of the element whose value is to be returned

Return Value

• the value of the indicated element.

MCallbackId& MCallbackIdArray:: operator[] ( unsigned int index )

Description

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.

Arguments

• index the index of the desired element

Return Value

• a reference to the indicated element

MCallbackIdArray & MCallbackIdArray:: operator= ( const MCallbackIdArray & other )

Description

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

Arguments

• other the array being copied

Return Value

• a reference to this array

MStatus MCallbackIdArray:: setLength ( unsigned int length )

Description

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).

Arguments

• size the new size of the array

unsigned int MCallbackIdArray:: length () const

Description

Returns the number of elements in the instance.

Return Value

• the number of elements in the instance

MStatus MCallbackIdArray:: remove ( unsigned int index )

Description

Remove the array element at the given index. All array elements following the removed element are shifted toward the first element.

Arguments

• index index of the element to be removed

Return Value

• MS::kSuccess if the remove was successful and MS::kFailure otherwise

MStatus MCallbackIdArray:: insert ( MCallbackId element, unsigned int index )

Description

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.

Arguments

• element the new value to insert into the array
• index the index of the element to set to the new value

Return Value

• MS::kSuccess if the insert was successful and MS::kFailure otherwise

MStatus MCallbackIdArray:: set ( MCallbackId element, unsigned int index )

Description

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

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

Arguments

• element the new value for the indicated element
• index the index of the element that is to be set to the the new value

Return Value

• MS::kSuccess if the value was set successfully and MS::kFailure otherwise

MStatus MCallbackIdArray:: append ( MCallbackId element )

Description

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.

Arguments

• element the value for the new last element

Return Value

• MS::kSuccess if the append was successful and MS::kFailure otherwise

MStatus MCallbackIdArray:: copy ( const MCallbackIdArray & source )

Description

Copy the contents of the source array to this array.

Arguments

• source array to copy from

Return Value

• MS::kSuccess if the copy was successful and MS::kFailure otherwise

MStatus MCallbackIdArray:: clear ()

Description

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 MCallbackIdArray:: get ( MCallbackId array[] ) const

Description

Copy the elements of the array into the given array of MCallbackIds. No checking is done to ensure that the destination C++ array of MCallbackIds is large enough to hold all the elements of the instance.

Arguments

• array the array to populate

Return Value

• MS::kSuccess if the array argument is a non-zero pointer and MS::kFailure otherwise

void MCallbackIdArray:: setSizeIncrement ( unsigned int newIncrement )

Description

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

Arguments

• newIncrement the new increment

unsigned int MCallbackIdArray:: sizeIncrement () const

Description

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

Return Value

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

std::ostream& operator<< (std::ostream &os, const MCallbackIdArray &array)

Description

Print the contents of the given MCallbackIdArray on the given ostream. The format used is [1, 2, 3, ... 9].

Arguments

• os the ostream to print to
• array the MCallbackIdArray whose value is to be printed

Return Value

• the ostream reference, s, provided as the first parameter.

This class has no child classes.
