Available on all platforms

Constructor

new()

Creates a new Array.

Variables

read onlylength:Int

The length of this Array.

Methods

concat(a:Array<T>):Array<T>

Returns a new Array by appending the elements of a to the elements of this Array.

This operation does not modify this Array.

If a is the empty Array [], a copy of this Array is returned.

The length of the returned Array is equal to the sum of this.length and a.length.

If a is null, the result is unspecified.

contains(x:T):Bool

Returns whether this Array contains x.

If x is found by checking standard equality, the function returns true, otherwise the function returns false.

copy():Array<T>

Returns a shallow copy of this Array.

The elements are not copied and retain their identity, so a[i] == a.copy()[i] is true for any valid i. However, a == a.copy() is always false.

inlinefilter(f:T ‑> Bool):Array<T>

Returns an Array containing those elements of this for which f returned true.

The individual elements are not duplicated and retain their identity.

If f is null, the result is unspecified.

indexOf(x:T, ?fromIndex:Int):Int

Returns position of the first occurrence of x in this Array, searching front to back.

If x is found by checking standard equality, the function returns its index.

If x is not found, the function returns -1.

If fromIndex is specified, it will be used as the starting index to search from, otherwise search starts with zero index. If it is negative, it will be taken as the offset from the end of this Array to compute the starting index. If given or computed starting index is less than 0, the whole array will be searched, if it is greater than or equal to the length of this Array, the function returns -1.

insert(pos:Int, x:T):Void

Inserts the element x at the position pos.

This operation modifies this Array in place.

The offset is calculated like so:

• If pos exceeds this.length, the offset is this.length.
• If pos is negative, the offset is calculated from the end of this Array, i.e. this.length + pos. If this yields a negative value, the offset is 0.
• Otherwise, the offset is pos.

If the resulting offset does not exceed this.length, all elements from and including that offset to the end of this Array are moved one index ahead.

inlineiterator():ArrayIterator<T>

Returns an iterator of the Array values.

join(sep:String):String

Returns a string representation of this Array, with sep separating each element.

The result of this operation is equal to Std.string(this[0]) + sep + Std.string(this[1]) + sep + ... + sep + Std.string(this[this.length-1])

If this is the empty Array [], the result is the empty String "". If this has exactly one element, the result is equal to a call to Std.string(this[0]).

If sep is null, the result is unspecified.

inlinekeyValueIterator():ArrayKeyValueIterator<T>

Returns an iterator of the Array indices and values.

lastIndexOf(x:T, ?fromIndex:Int):Int

Returns position of the last occurrence of x in this Array, searching back to front.

If x is found by checking standard equality, the function returns its index.

If x is not found, the function returns -1.

If fromIndex is specified, it will be used as the starting index to search from, otherwise search starts with the last element index. If it is negative, it will be taken as the offset from the end of this Array to compute the starting index. If given or computed starting index is greater than or equal to the length of this Array, the whole array will be searched, if it is less than 0, the function returns -1.

inlinemap<S>(f:T ‑> S):Array<S>

Creates a new Array by applying function f to all elements of this.

The order of elements is preserved.

If f is null, the result is unspecified.

pop():Null<T>

Removes the last element of this Array and returns it.

This operation modifies this Array in place.

If this has at least one element, this.length will decrease by 1.

If this is the empty Array [], null is returned and the length remains 0.

push(x:T):Int

Adds the element x at the end of this Array and returns the new length of this Array.

This operation modifies this Array in place.

this.length increases by 1.

remove(x:T):Bool

Removes the first occurrence of x in this Array.

This operation modifies this Array in place.

If x is found by checking standard equality, it is removed from this Array and all following elements are reindexed accordingly. The function then returns true.

If x is not found, this Array is not changed and the function returns false.

resize(len:Int):Void

Set the length of the Array.

If len is shorter than the array's current size, the last length - len elements will be removed. If len is longer, the Array will be extended, with new elements set to a target-specific default value:

• always null on dynamic targets
• 0, 0.0 or false for Int, Float and Bool respectively on static targets
• null for other types on static targets

reverse():Void

Reverse the order of elements of this Array.

This operation modifies this Array in place.

If this.length < 2, this remains unchanged.

shift():Null<T>

Removes the first element of this Array and returns it.

This operation modifies this Array in place.

If this has at least one element, this.length and the index of each remaining element is decreased by 1.

If this is the empty Array [], null is returned and the length remains 0.

slice(pos:Int, ?end:Int):Array<T>

Creates a shallow copy of the range of this Array, starting at and including pos, up to but not including end.

This operation does not modify this Array.

The elements are not copied and retain their identity.

If end is omitted or exceeds this.length, it defaults to the end of this Array.

If pos or end are negative, their offsets are calculated from the end of this Array by this.length + pos and this.length + end respectively. If this yields a negative value, 0 is used instead.

If pos exceeds this.length or if end is less than or equals pos, the result is [].

sort(f:(T, T) ‑> Int):Void

Sorts this Array according to the comparison function f, where f(x,y) returns 0 if x == y, a positive Int if x > y and a negative Int if x < y.

This operation modifies this Array in place.

The sort operation is not guaranteed to be stable, which means that the order of equal elements may not be retained. For a stable Array sorting algorithm, haxe.ds.ArraySort.sort() can be used instead.

If f is null, the result is unspecified.

splice(pos:Int, len:Int):Array<T>

Removes len elements from this Array, starting at and including pos, an returns them.

This operation modifies this Array in place.

If len is < 0 or pos exceeds this.length, an empty Array [] is returned and this Array is unchanged.

If pos is negative, its value is calculated from the end of this Array by this.length + pos. If this yields a negative value, 0 is used instead.

If the sum of the resulting values for len and pos exceed this.length, this operation will affect the elements from pos to the end of this Array.

The length of the returned Array is equal to the new length of this Array subtracted from the original length of this Array. In other words, each element of the original this Array either remains in this Array or becomes an element of the returned Array.

toString():String

Returns a string representation of this Array.

The result will include the individual elements' String representations separated by comma. The enclosing [ ] may be missing on some platforms, use Std.string() to get a String representation that is consistent across platforms.

unshift(x:T):Void

Adds the element x at the start of this Array.

This operation modifies this Array in place.

this.length and the index of each Array element increases by 1.
