This XQuery Module contains functions for manipulating arrays, which will officially be introduced with XQuery 3.1.

Conventions

All functions in this module are assigned to the http://www.w3.org/2005/xpath-functions/array namespace, which is statically bound to the array prefix.

Functions

Signatures	`array:size($input as array(*)) as xs:integer`
Summary	Returns the number of members in the supplied array. Note that because an array is an item, the `fn:count` function when applied to an array always returns `1`.
Examples	`array:size([1 to 10])` returns `10`. `array:size(array { 1 to 10 })` returns `10`.

Signatures	`array:append($input as array(), $insert as item()) as array(*)`
Summary	Adds one member at the end of the array. The result is an array whose size is `array:size($array) + 1`, in which all members in positions `1` to `array:size($array)` are the same as the members in the corresponding position of $array, and the member in position `array:size($array) + 1` is `$insert`.
Examples	* `array:append([], 'member1')` returns the array `["member1"]`.

Signatures	`map:serialize($input as map(*)) as xs:string`
Summary	This function is specific to BaseX. It returns a string representation of the supplied array. The purpose of this function is to get an insight into the structure of an array item; it cannot necessarily be used for reconstructing the original array.
Examples	`array:serialize([ 1, (2, 3), 4 to 6 ])` returns `[1, (2, 3), (4, 5, 6)]`.
