Array : The array object

 

Constructors

  • () - Creates an empty array.
  • (number count) - Creates an array with a predefined size, where all elements are Empty. Count is a number type, it is number of items to put in the array.

Methods

  • Empty Add(AnyType element) - Add a new element to the Array.
  • number Frequency(number Number) - Counts the number of times a given Number object exists in the Array. Can only use if all the elements are of type number. Number is the number to search for.
  • bool IsCharacterArray() - Check if array is an array of characters.
  • bool IsNumericArray() - Check if array is an array of numbers.
  • bool IsNumericArray() - Check if array is an array of integer numbers.
  • bool IsStringArray() - Check if array is an array of string.
  • Empty set_Item(number index, AnyType value) - Set element value at index.
  • AnyType get_Item(number index) - Get element at index.
  • Empty RemoveItemAt(number index) - Remove an element from the Array. index is the index to remove the object from.
  • string ToString() - The string representation of the object.
  • array Select(Function selector) - Projects each element of a sequence into a new form. selector is a transform function to apply to each element.
  • array Where(Function predicate) - Filters a sequence of values based on a predicate. predicate is a function that takes 1 parameter of the types in the array and return true/false.
  • array OrderBy(Function comparer) - Sorts the elements of a sequence in ascending order by using a specified comparer. comparer is a Function that compares two objects of the same type. Must return a signed integer that indicates the relative values of first param A and second param B. Value Less than 0 : A is less than B.Value 0 : A equals B.Value Greater than 0 : A is greater than B.
  • AnyType First(Function selector) - Returns the first element in a sequence that satisfies a specified condition. selector is a function to test each element for a condition.
  • AnyType FirstOrDefault(Function selector) - Returns the first element in a sequence that satisfies a specified condition or empty if not found. selector is a function to test each element for a condition.

Properties

  • number Average HasGetter  - Average of the objects in the Array object. Can only use if all the elements are of type Number.
  • number Count HasGetter  - Number of elements in Array.
  • number Max HasGetter  - Largest of all the objects in the Array object. Can only use if all the elements are of type Number.
  • number Min HasGetter  - Smallest of all the objects in the Array object. Can only use if all the elements are of type Number.
  • string ObjectTypeName HasGetter  - The name of the type of object.
  • number Sum HasGetter  - Sum of all the objects in the Array object. Can only use if all the elements are of type Number.
  • TypeInformation TypeInformation HasGetter  - Get information about this class.

 

Examples

 

array x = new Array();

print(x);                                //   {}

 

array x = new Array(10);

print(x);                                //   {Empty,Empty,Empty,Empty,Empty,Empty,Empty,Empty,Empty,Empty}

 

array x = {10,20,30,40,50,60,70,80,90,100};

array y = x

.Select(function (number a) { a;})

// .Select(function (string a) { a;})  -> will not work: Cannot assign a value of type 'Number' to a variable of type 'String'

// .Select(function (array a) { a;})  -> will not work: Cannot assign a value of type 'Number' to a variable of type 'Array'

// .Select(function (bool a) { a;})  -> will not work: Cannot assign a value of type 'Number' to a variable of type 'Boolean'

// .Select(function () { a;})       -> will not work: Function called with too many parameters @

.Where(function (number a) {number i = getRandomNumber(0,10)*10; i > 40;});

print(y);  

 

array x = {10,20,30,40,50,60,70,80,90,100};

array y = x

.Select(function (number a) { 88888;})

.Where(function (number a) {number i = getRandomNumber(0,10)*10; i > 40;});

print(y);  

 

array x = {10,20,30,40,50,60,70,80,90,100};

array y = x

.Select(function (number a) { a;})

.Where(function (number a) {number i = getRandomNumber(0,10)*10; i > 40;})

.OrderBy(function(number a, number b) {if (a>b) 1; else if (a<b) -1; else 0;});

// .OrderBy(function(number a, number b){if (a>b) -1; else if (a<b) 1; else 0;});

print(y); 

 

array x = {{1,2,3},{4,false,6,7,8},{10,"ab",{"aaa",11,true},13,14},{"aa","bb",17},{},{true,88}};

array y = x

.Select(function (array a) {; a;})

.Where(function (array a) {arrayCount(a) > 3;});

print(y);                               //     {{4,False,6,7,8},{10,ab,{aaa,11,True},13,14}}

 

array y = {20,30,40,50,70,80,90,100};

print(y.FirstOrDefault(function (number a) { true; }));                                 // 20

print(y.FirstOrDefault(function (number a) { a > 70; }));                             // 80

print(y.First(function(number a) { true; }));                                               // 20

print(y.First(function(number a) { a > 40; }));                                           // 50
