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;})

.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
