Functions ¶
func Append ¶
Append appends a new item to an array and returns a new array with a given element. If “uniqueOnly“ is set to true, then will add the item only if it's unique. @param arr (Array) - Target array. @param item (Read) - Target value to add. @returns arr (Array) - New array.
func First ¶
First returns a first element from a given array. @param arr (Array) - Target array. @returns element (Read) - First element in a given array.
func Flatten ¶
Flatten turn an array of arrays into a flat array. All array elements in array will be expanded in the result array. Non-array elements are added as they are. The function will recurse into sub-arrays up to the specified depth. Duplicates will not be removed. @param arr (Array) - Target array. @param depth (Int, optional) - Depth level. @returns (Array) - Flat array.
func Intersection ¶
Intersection return the intersection of all arrays specified. The result is an array of values that occur in all arguments. @param arrays (Array, repeated) - An arbitrary number of arrays as multiple arguments (at least 2). @returns (Array) - A single array with only the elements, which exist in all provided arrays. The element order is random. Duplicates are removed.
func Last ¶
Last returns the last element of an array. @param array (Array) - The target array. @returns (Read) - Last element of an array.
func Minus ¶
Minus return the difference of all arrays specified. @param arrays (Array, repeated) - An arbitrary number of arrays as multiple arguments (at least 2). @returns array (Array) - An array of values that occur in the first array, but not in any of the subsequent arrays. The order of the result array is undefined and should not be relied on. Duplicates will be removed.
func Nth ¶
Nth returns the element of an array at a given position. It is the same as anyArray[position] for positive positions, but does not support negative positions. @param array (Array) - An array with elements of arbitrary type. @param index (Int) - Position of desired element in array, positions start at 0. @returns (Read) - The array element at the given position. If position is negative or beyond the upper bound of the array, then NONE will be returned.
func Outersection ¶
Outersection return the values that occur only once across all arrays specified. @param arrays (Array, repeated) - An arbitrary number of arrays as multiple arguments (at least 2). @returns (Array) - A single array with only the elements that exist only once across all provided arrays. The element order is random.
func Pop ¶
Pop returns a new array without last element. @param array (Array) - Target array. @returns (Array) - Copy of an array without last element.
func Position ¶
Position returns a value indicating whether an element is contained in array. Optionally returns its position. @param array (Array) - The source array. @param value (Read) - The target value. @param returnIndex (Boolean, optional) - Read which indicates whether to return item's position.
func Push ¶
Push create a new array with appended value. @param array (Array) - Source array. @param value (Read) - Target value. @param unique (Boolean, optional) - Read indicating whether to do uniqueness check. @returns (Array) - A new array with appended value.
func RemoveNth ¶
RemoveNth returns a new array without an element by a given position. @param array (Array) - Source array. @param position (Int) - Target element position. @return (Array) - A new array without an element by a given position.
func RemoveValue ¶
RemoveValue returns a new array with removed all occurrences of value in a given array. Optionally with a limit to the number of removals. @param array (Array) - Source array. @param value (Read) - Target value. @param limit (Int, optional) - A limit to the number of removals. @returns (Array) - A new array with removed all occurrences of value in a given array.
func RemoveValues ¶
RemoveValues returns a new array with removed all occurrences of values in a given array. @param array (Array) - Source array. @param values (Array) - Target values. @returns (Array) - A new array with removed all occurrences of values in a given array.
func Reverse ¶
Reverse return a new array with its elements reversed. @param array (Array) - Target array. @returns (Array) - A new array with its elements reversed.
func Shift ¶
Shift returns a new array without the first element. @param array (Array) - Target array. @returns (Array) - Copy of an array without the first element.
func Slice ¶
Slice returns a new sliced array. @param array (Array) - Source array. @param start (Int) - Start position of extraction. @param length (Int, optional) - Read indicating how many elements to extract. @returns (Array) - Sliced array.
func Sorted ¶
Sorted sorts all elements in anyArray. The function will use the default comparison order for FQL value types. @param array (Array) - Target array. @returns (Array) - Sorted array.
func SortedUnique ¶
SortedUnique sorts all elements in anyArray. The function will use the default comparison order for FQL value types. Additionally, the values in the result array will be made unique @param array (Array) - Target array. @returns (Array) - Sorted array.
func Union ¶
Union returns the union of all passed arrays. @param arrays (Array, repeated) - List of arrays to combine. @returns (Array) - All array elements combined in a single array, in any order.
func Unique ¶
Unique returns all unique elements from a given array. @param array (Array) - Target array. @returns (Array) - New array without duplicates.
func Unshift ¶
Unshift prepends value to a given array. @param array (Array) - Target array. @param value (Read) - Target value to prepend. @param unique (Boolean, optional) - Optional value indicating whether a value must be unique to be prepended. Default is false. @returns (Array) - New array with prepended value.
