Integer |
Converts list of arbitrary objects into an integer array. This is done by creating an integer alphabet, which maps each unique element in the original list(s) to an integer value. The lexicographical order of the elements is maintained, i.e.
when a list of elements of ascending order is mapped to an integer list, the integer list is also in ascending order.

public class IntegerText
The IntegerText type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | IntegerText | Initializes a new instance of the IntegerText class |
Properties| Name | Description | |
|---|---|---|
 | AlphabetSize | Size of the alphabet, i.e. the number of unique elements that occur in the original text (or, number of unique list elements). If the text was separated into individual words, the number of words (= number of separator elements) also contribute to the alphabet size. |
| NumberOfWords | Number of words, if the text was separated into individual words. Otherwise, this field is equal to one. |
| PaddingLength | Number of additional elements of array Text. Thus the length of this array is PaddingLength + TextLength |
| Text | Original text, converted to an integer alphabet. Each unique element of the original text (or each unique list element) corresponds to an integer value. The order of this integer alphabet is the same as the order of the original elements. Note that the value 0 is reserved for the internal algorithm. If the original text was separated in different words, the first numberOfWords integers (1..numberOfWords) are reserved as separator elements, too. |
| TextLength | Length of the text. This is the total length of the original text, plus, if the text was separated into words, the number of separator elements (which is equal to the number of words). Note that the array _text is needed to be longer than _textLength, since some additional elements are neccessary for most algorithms. |
| WordStartPositions | Start positions of the words in which the original text was separated in the array _text. |
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
 | FromWords(IEnumerableString, Boolean, Int32, IComparerChar) | Generates an integer text from words (= a collection of strings). The algorithm determines the lexicographical order of all elements in all lists and then maps each unique element to an integer value, with increasing values in the lexicographical order of the elements. |
| FromWordsT(IEnumerableIEnumerableT, Boolean, Int32, Boolean, IComparerT) | Generates an integer text from arbitrary elements. Each list in lists is treated as separate word. Each element is such a list is treated as character. The algorithm determines the lexicographical order of all elements in all lists and then maps each unique element to an integer value, with increasing values in the lexicographical order of the elements. A unique mapping is even possible, if the elements are not sortable (i.e. if they not implement IComparable). |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
