.first

Return the first element of the collection.

.last

Return the last element of the collection.

.putFirst(obj)

.putLast(obj)

Place item at the first / last index in the collection. Note that if the collection is empty (and therefore has no indexed slots) the item will not be added.

.indexOf(item)

Return the index of an item in the collection, or nil if not found. Elements are checked for identity (not for equality).

.indexOfEqual(item, offset: 0)

Return the index of something in the collection that equals the item, or nil if not found.

.indicesOfEqual(item)

Return an array of indices of things in the collection that equal the item, or nil if not found.

.indexOfGreaterThan(val)

Return the first index containing an item which is greater than item.

.selectIndices(function)

Return a new collection of same type as receiver which consists of all indices of those elements of the receiver for which function answers true. The function is passed two arguments, the item and an integer index.

If you want to control what type of collection is returned, use -selectIndicesAs

.selectIndicesAs(function, class)

Return a new collection of type class which consists of all indices of those elements of the receiver for which function answers true. The function is passed two arguments, the item and an integer index.

.rejectIndices(function)

Return a new collection of same type as receiver which consists of all indices of those elements of the receiver for which function answers false. The function is passed two arguments, the item and an integer index.

If you want to control what type of collection is returned, use -rejectIndicesAs

.rejectIndicesAs(function, class)

Return a new collection of type class which consists of all indices of those elements of the receiver for which function answers false. The function is passed two arguments, the item and an integer index.

.maxIndex(function)

From superclass: Collection

Answer the index of the maximum of the results of function evaluated for each item in the receiver. The function is passed two arguments, the item and an integer index. If function is nil, then answer the maximum of all items in the receiver.

.minIndex(function)

From superclass: Collection

Answer the index of the minimum of the results of function evaluated for each item in the receiver. The function is passed two arguments, the item and an integer index. If function is nil, then answer the minimum of all items in the receiver.

.find(sublist, offset: 0)

If the sublist exists in the receiver (in the specified order), at an offset greater than or equal to the initial offset, then return the starting index. The sublist must be of the same kind (class) as the list to search in. Elements are checked for equality (not for identity).

.findAll(arr, offset: 0)

From superclass: Object

Returns a linearly interpolated value between the two closest indices. Inverse operation is -indexInBetween.

.copyRange(start, end)

Return a new SequenceableCollection which is a copy of the indexed slots of the receiver from start to end. If end < start, an empty collection is returned.

WARNING: x.copyRange(a, b) is not equivalent to x[a..b]. The latter compiles to ArrayedCollection: -copySeries, which has different behavior when end < start.

.copyToEnd(start)

Return a new SequenceableCollection which is a copy of the indexed slots of the receiver from start to the end of the collection. x.copyToEnd(a) can also be written as x[a..]

.copyFromStart(end)

.take(item)

Remove and return item from collection. The last item in the collection will move to occupy the vacated slot (and the collection size decreases by one). See also takeAt, defined for ArrayedCollection: -takeAt. Elements are checked for identity (not for equality).

WARNING: take(item) works on Arrays but not on Lists, because the internally called method takeAt(item) is not defined for Lists.

.obtain(index, default)

.sortBy(key)

Sort the contents of the collection using the key key, which is assumed to be found inside each element of the receiver.

.order(function)

If the collection contains only one element, it is returned as the result. If the collection is empty, returns nil.

Arguments:

operator

May be a Function (taking two or three arguments) or a Symbol (method selector).

adverb

.hammingDistance(that)

Returns the count of array elements that are not equal in identical positions. http://en.wikipedia.org/wiki/Hamming_distance

The collections are not wrapped - if one array is shorter than the other, the difference in size should be included in the count.

Fuzzy comparisons

With fuzzy comparisons, the arrays do not need to match exactly. We can check how similar they are, and make decisions based on that. This is the magic behind autocorrection.

.editDistance(other, compareFunc)

Returns the mininum number of changes to modify this SequenceableCollection into the other SequenceableCollection. A change can be: an addition, a deletion, or a substitution. This is known as the Levenshtein Distance and is implemented in SuperCollider using the Wagner–Fischer algorithm.

The default comparison uses identity - see Object: -== and Object: -===

Where both arrays are raw arrays (String, Int16Array, Int32Array, FloatArray etc., or any derived classes), like comparing two strings, a faster primitive will be used to calculate the distance.

In cases where the arrays are of different types, it will fall back to a slower, non-primitive implementation.

For cases that require comparisons other than identity, the optional compareFunc can be given to compare elements. This function will be passed two arguments, representing a single element from each array to compare, and this function must return a boolean as to whether or not the elements are equal.

NOTE: Specifying a compareFunc will bypass the primitive and may take significantly longer to execute for larger arrays.

Arguments:

other

The SequenceableCollection to compare against

compareFunc

An optional comparison function to use for each element. It will be provided two arguments, and the function must return a boolean as to whether or not they are the same. Default value is nil, which will use identity (not equality) to compare elements.

.similarity(other, compareFunc)

Returns a value between 0 and 1 representing the percentage similarity between this SequenceableCollection and the other SequenceableCollection.

A value of 1 means they are exactly the same, a value of 0 means they are completely different. This is calculated based on the -editDistance

Arguments:

other

The SequenceableCollection to compare against

compareFunc

An optional compareFunc to be used to calculate the edit distance (see -editDistance)

Math Support - Special Functions

A variety of Special Functions are supplied by the Boost C++ library. The library's online documentation serves as the primary reference for the following functions. The methods here match closely with those found in the source library, as do argument names.

Below you'll find descriptions of the functions and their bounds, but for visualizing the functions, have a look in Tour of Special Functions.

NOTE: The following methods are documented slightly clearer in SimpleNumber: Special Functions using functional notation. As of this writing, a bug in the help file formatting misleadingly documents the methods in receiver notation (methods preceded by .), but should be read to suggests the usage: foo([a], [b]). The equivalent receiver notation is: [a].foo([b]). Note that those methods with only one argument erroneously omit that argument from the argument list; each element in the collection is implicitly passed as the method's argument, e.g. foo([a]) or [a].foo
WARNING: Many of the functions are only valid in certain numerical ranges. For the most part, error handling happens in the underlying boost functions. While these errors are often obtuse, you'll usually find a useful message at the end of the error regarding proper ranges and the erroneous value supplied. Refer to the online documentation for more detailed descriptions, and the Tour of Special Functions for plots showing ranges and asymptotes.

.multichannelExpandRef(rank)

This method is called internally on inputs to UGens that take multidimensional arrays, like Klank and it allows proper multichannel expansion even in those cases. For SequenceableCollection, this returns the collection itself, assuming that it contains already a number of Refs. See Ref for the corresponding method implementation.

Arguments:

rank

The depth at which the list is expanded. For instance the Klank spec has a rank of 2. For more examples, see SequenceableCollection: -flopDeep

Rhythm-lists

.convertRhythm

Convert a rhythm-list to durations.

Discussion:

supports a variation of Mikael Laurson's rhythm list RTM-notation.1

The method converts a collection of the form [beat-count, [rtm-list], repeats] to a List of Floats. A negative integer within the rtm-list equates to a value tied over to the duration following. The method is recursive in that any subdivision within the rtm-list can itself be a nested convertRhythm collection (see example below). The repeats integer has a default value of 1.

If the divisions in the rtm-list are events, the event durations are interpreted as relative durations, and a list of events is returned.

Starting UNIX processes

.unixCmd(action, postOutput: true)

Execute a UNIX command asynchronously. This object should be an array of strings where the first string is the path to the executable to be run and all other strings are passed as arguments to the executable. This method starts the process directly without using a shell.

Arguments:

action

A Function that is called when the process has exited. It is passed two arguments: the exit code and pid of the exited process.

postOutput

A Boolean that controls whether or not the output of the process is displayed in the post window.

Returns:

An Integer - the pid of the newly created process. Use Integer: -pidRunning to test if a process is alive.

Discussion:

Example:

.unixCmdGetStdOut(maxLineLength: 1024)

Similar to -unixCmd except that the stdout of the process is returned (synchronously) rather than sent to the post window. This object should be an array of strings where the first string is the path to the executable to be run and all other strings are passed as arguments to the executable. This method starts the process directly without using a shell.
