Methods
Append an element to the vector. This works just like insertAt() with a starting index one higher than the length of the vector. This has almost the same effect as the '+' operator, but treats a list value like any other value by simply inserting the list as a single new element (rather than appending each item in the list individually, as the '+' operator would).
append the elements of the list or array 'val' to the elements of this array, then remove repeated elements in the result; returns a new array with the unique elements of the combination
Apply a callback function to each element of the array. For each element of the array, invokes the callback, and replaces the element with the return value of the callback. Modifies the array in-place, and returns 'self'.
copyFrom (src, src_start, dst_start, cnt) | array.h[38] |
Copy from another array or list. Elements are copied from the source array or list starting at the element given by 'src_start', and are copied into 'self' starting at the index given by 'dst_start'. At most 'cnt' values are copied, but we stop when we reach the last element of either the source or destination values.
count the number of elements with the given value
count the number of elements for which the callback returns true
fill with a given value, starting at the given element (the first element if not specified), and running for the given number of elements (the remaining elements of the array, if not not specified)
Invoke the callback on each element, in order from first to last. No return value.
create a new array consisting of the unique elements of this array
get the index of the first match for the given value
Find the first element for which the given condition is true. Apply the callback function (which encodes the condition to evaluate) to each element in turn, starting with the first. For each element, if the callback returns nil, proceed to the next element; otherwise, stop and return the index of the element. If the callback never returns true for any element, we'll return nil.
find the last element with the given value, and return its index
Find the last element for which the condition is true, and return the index of the element. Applies the callback to each element in turn, starting with the last element and working backwards. For each element, if the callback returns nil, proceeds to the previous element; otherwise, stops and returns the index of the element. If the callback never returns true for any element, we'll return nil.
Find the last element for which the condition is true, and return the value of the element
get the number of elements in the array
Apply the callback function to each element of this array, and return a new array consisting of the results. Effectively maps the array to a new array using the given function, leaving the original array unchanged.
sort (descending?, comparisonFunction?) | array.h[148] |
Sort the array in place; returns 'self'. If the 'descending' flag is provided and is not nil, we'll sort the array in descending order rather than ascending order.
If the 'comparisonFunction' argument is provided, it must be a callback function; the callback takes two arguments, and returns an integer less than zero if the first argument value is less than the second, zero if they're equal, and an integer greater than zero if the first is greater than the second. If no 'comparisonFunction' argument is provided, or it's provided and its value is nil, we'll simply compare the array elements as ordinary values. The comparison function can be provided for caller-defined orderings, such as ordering a set of objects.
Select a subset of the array. Returns a new array consisting only of the elements of this array for which the callback function returns true.
Create a list with the same elements as the array. If 'start' is specified, it's the index of the first element we store; we'll store elements starting at index 'start'. If 'cnt' is specified, it gives the maximum number of elements for the new list; by default, we'll store all of the elements from 'start' to the last element.
Find the first element for which the given condition is true, and return the value of the element.
