Detailed Description

Various utilities for handling arrays and memory.

Static Public Member Functions
static void	MemSet< T > (T[] array, T value, int byteSize)
	Sets all values in an array to a specific value faster than a loop.
static void	MemSet< T > (T[] array, T value, int totalSize, int byteSize)
	Sets all values in an array to a specific value faster than a loop.
static T[]	ShrinkArray< T > (T[] arr, int newLength)
	Returns a new array with at most length newLength.

Member Function Documentation

static void MemSet< T > ( T[]  array, T  value, int  byteSize  )

static

Sets all values in an array to a specific value faster than a loop.

Only faster for large arrays. Slower for small ones. Tests indicate it becomes faster somewhere when the length of the array grows above around 100. For large arrays this can be magnitudes faster. Up to 40 times faster has been measured.

Note

Only works on primitive value types such as int, long, float, etc.

Parameters

array	the array to fill
value	the value to fill the array with
byteSize	size in bytes of every element in the array. e.g 4 bytes for an int, or 8 bytes for a long. It can be efficiently got using the sizeof built-in function.

//Set all values to 8 in the array
int[] arr = new int[20000];
Pathfinding.Util.Memory.MemSet<int> (arr, 8, sizeof(int));

Type Constraints

T

:

struct

static void MemSet< T > ( T[]  array, T  value, int  totalSize, int  byteSize  )

static

Sets all values in an array to a specific value faster than a loop.

Only faster for large arrays. Slower for small ones. Tests indicate it becomes faster somewhere when the length of the array grows above around 100. For large arrays this can be magnitudes faster. Up to 40 times faster has been measured.

Parameters

array	the array to fill
value	the value to fill the array with
byteSize	size in bytes of every element in the array. e.g 4 bytes for an int, or 8 bytes for a long.
totalSize	all indices in the range [0, totalSize-1] will be set

It can be efficiently got using the sizeof built-in function.

//Set all values to 8 in the array
int[] arr = new int[20000];
Pathfinding.Util.Memory.MemSet<int> (arr, 8, sizeof(int));

Type Constraints

T

:

struct

static T [] ShrinkArray< T > ( T[]  arr, int  newLength  )

static

Returns a new array with at most length newLength.

The array will contain a copy of all elements of arr up to but excluding the index newLength.
