Detailed Description

An array of Math.Vector2UL objects.

Constructor & Destructor Documentation

__init__() [1/2]

None CDPL.Math.Vector2ULArray.__init__

(

Vector2ULArray

array

)

Initializes a copy of the Vector2ULArray instance array.

Parameters

array

The Vector2ULArray instance to copy.

__init__() [2/2]

None CDPL.Math.Vector2ULArray.__init__

(

object

a

)

Initializes the Vector2ULArray instance.

Parameters

a

Member Function Documentation

getObjectID()

int CDPL.Math.Vector2ULArray.getObjectID

(

)

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python Vector2ULArray instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two Vector2ULArray instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns

The numeric ID of the internally referenced C++ class instance.

getSize()

int CDPL.Math.Vector2ULArray.getSize

(

)

Returns the number of elements stored in the array.

Returns

The size of the array.

isEmpty()

bool CDPL.Math.Vector2ULArray.isEmpty

(

)

Tells whether the array is empty (getSize() == 0).

Returns

True if the array is empty, False otherwise.

resize()

None CDPL.Math.Vector2ULArray.resize	(	int	num_elem,
		Vector2UL	value
	)

Inserts or erases elements at the end so that the size becomes num_elem.

Parameters

num_elem	The new size.
value	The value for newly inserted elements.

reserve()

None CDPL.Math.Vector2ULArray.reserve

(

int

num_elem

)

Preallocates memory for (at least) num_elem elements.

If num_elem is less than or equal to the current capacity, this call has no effect. Otherwise, it is a request for allocation of additional memory. If the request is successful, then the capacity is greater than or equal to num_elem. Otherwise, the capacity is unchanged. In either case, the number of elements will not change.

Parameters

num_elem

The number of elements to reserve memory for.

See also

getCapacity()

getCapacity()

int CDPL.Math.Vector2ULArray.getCapacity

(

)

Returns the number of elements for which memory has been allocated.

The capacity is always greater than or equal to the number of currently stored elements.

Returns

The current capacity.

assign() [1/3]

Vector2ULArray CDPL.Math.Vector2ULArray.assign

(

Vector2ULArray

array

)

Replaces the current state of self with a copy of the state of the Vector2ULArray instance array.

Parameters

array

The Vector2ULArray instance to copy.

Returns

self

assign() [2/3]

None CDPL.Math.Vector2ULArray.assign	(	int	num_elem,
		Vector2UL	value
	)

This function fills the array with num_elem copies of the given value.

Note that the assignment completely changes the array and the new size is the same as the number of elements assigned. Old data will be lost.

Parameters

num_elem	The number of elements to be assigned.
value	The value to be assigned.

assign() [3/3]

None CDPL.Math.Vector2ULArray.assign

(

object

a

)

Replaces the current state of self with a copy of the state of the object instance a.

Parameters

a	The object instance to copy.

Returns

self

addElement()

None CDPL.Math.Vector2ULArray.addElement

(

Vector2UL

value

)

Inserts a new element at the end of the array.

Parameters

value

The value of the new element.

addElements()

None CDPL.Math.Vector2ULArray.addElements

(

Vector2ULArray

values

)

Parameters

Inserts a new element before the location specified by the index idx.

Parameters

idx	The location where to insert the new element.
value	The value of the element to insert.

Exceptions

Base.IndexError

if the array is empty or idx is not in the range [0, getSize()].

insertElements() [1/2]

None CDPL.Math.Vector2ULArray.insertElements	(	int	idx,
		int	num_elem,
		Vector2UL	value
	)

Inserts num_elem copies of value before the location specified by the index idx.

Parameters

idx	The location where to insert the new elements.
num_elem	The number of elements to insert.
value	The value of the elements to insert.
