Class AsciiString

java.lang.Object

fiftyone.mobile.detection.entities.BaseEntity

fiftyone.mobile.detection.entities.AsciiString

public class AsciiString
extends BaseEntity

ASCII format strings are the only ones used in the data set.

Many native string formats use UNICODE format using 2 bytes for every character. This is inefficient when only ASCII values are being stored. The AsciiString class wraps a byte array of ASCII characters and exposes them as a native string type when required.

Strings stored as ASCII strings include, the relevant characters from signatures, sub strings longer than 4 characters, property and value names, the descriptions and URLs associated with properties and values.

Objects of this class should not be created directly as they are part of the internal logic.

For more information see: 51Degrees pattern data model.
