class ReArray [A] extends IndexedSeq[A] with GenericTraversableTemplate[A, ReArray] with IndexedSeqOptimized[A, ReArray[A]]
The ReArray class provides an implementation of mutable, resizable/dynamic arrays.
The ReArray class provides an implementation of mutable, resizable/dynamic arrays. It is based on Scala's ResizableArray trait with additions and modifications. Preliminary testing has shown it to be faster than its competition: ArrayList and ArrayBuffer. ------------------------------------------------------------------------------------------- Added methods: 'shiftLeft', 'shiftLeft2', 'shiftRight', 'shiftRight2' and 'expand'. ------------------------------------------------------------------------------------------- Modified methods: 'reduceToSize': modified for performance reasons; instead of decreasing the size0 by 1 in a while loop and setting elements to null, it just decrements the size0 variable. FIX: possible minor memory leak 'companion': modified to return null as it is not required by our implementation; the ReArray object does not extend SeqFactory and thus 'newBuilder [A]' is absent. 'update': modified to catch the IndexOutOfBoundsException' and automatically expand the array. 'constructor': modified to take in the initial length and a normalArray; by doing this we can easily convert an object of typeArray to a ReArrayas the internal 'array' is changed fromAnyRef to type A'. ------------------------------------------------------------------------------------------- Modified variables: 'array': the type is changed to A from AnyRef; this helps in assigning an Array [A] to a ReArray [A]; the initial value is changed to check if '_array' is null. 'size0': the initial value is changed to take care if '_array' is null. -------------------------------------------------------------------------------------------

object Unicode
The Unicode object provides arrays to facilitate the use of Unicode.
The Unicode object provides arrays to facilitate the use of Unicode. ScalaTion currently uses a few UTF-16 characters, see code below. Most UTF-16 characters are 2 bytes (16 bits). Extended characters are encoded in 4 bytes. ScalaTion limits characters to the range 'U+0000' to 'U+2bff'. Developers should test Unicode symbols here before trying them in the code.
