Sequential strategies provide ways to compositionally specify the degree of evaluation of a data type between the extremes of no evaluation and full evaluation. Sequential strategies may be viewed as complimentary to the parallel ones (see module Control.Parallel.Strategies).
General-purpose finite sequences.
General purpose finite sequences. Apart from being finite and having strict operations, sequences also differ from lists in supporting a wider variety of operations efficiently.
An amortized running time is given for each operation, with n referring to the length of the sequence and i being the integral index used by some operations. These bounds hold even in a persistent (shared) setting.
The implementation uses 2-3 finger trees annotated with sizes, as described in section 4.2 of
* Ralf Hinze and Ross Paterson, "Finger trees: a simple general-purpose data structure", Journal of Functional Programming 16:2 (2006) pp 197-217. http://www.soi.city.ac.uk/~ross/papers/FingerTree.html
Note: Many of these operations have the same names as similar operations on lists in the Prelude. The ambiguity may be resolved using either qualification or the hiding clause.
a name for Control.Seq.Strategy, for documetnation only.
Evaluates its first argument to head normal form, and then returns its second argument as the result.
Evaluate each action in the sequence from left to right, and collect the results.
Evaluate each action in the sequence from left to right, and ignore the results.
Evaluate each monadic action in the structure from left to right, and ignore the results.
Evaluate each action in the structure from left to right, and ignore the results.
Evaluate the elements of an array according to the given strategy. Evaluation of the array bounds may be triggered as a side effect.
Evaluate the bounds of an array according to the given strategy.
Evaluate the elements of a foldable data structure according to the given strategy.
Evaluate each element of a list according to the given strategy. This function is a specialisation of seqFoldable to lists.
Evaluate the first n elements of a list according to the given strategy.
Evaluate the nth element of a list (if there is such) according to the given strategy. The spine of the list up to the nth element is evaluated as a side effect.
Handle sequence locations for bioinformatics
Read and write BED and GTF format genome annotations
Evaluate the keys and values of a map according to the given strategies.
Sequential index numbers between 0.0 and 1.0 that allow arbitrarily inserting new numbers in between. They can possibly used for disk-based and other special containers, where adding a new element without changing the indexes of the other elements is important. Conceptually, SequentialIndex denotes a path to an element in an imaginary binary tree. However, leafs can only be on the right side of their parent. I.e. the path must end with a '1' (or be the path to the root node, 0.0). 1.0 denotes the invalid node.
A sequence labeler based on Collins's sequence perceptron.
The subsequences function returns the list of all subsequences of the argument.
> subsequences "abc" == ["","a","b","ab","c","ac","bc","abc"]
This package provides access to ALSA sequencer (MIDI support). For audio support see alsa-pcm. Included are some simple example programs. For more example programs including a GUI, see the alsa-gui programs.
