      extended by org.apache.directory.shared.ldap.schema.syntax.JpegSyntaxChecker
All Implemented Interfaces:
SyntaxChecker

public class JpegSyntaxChecker
extends AbstractSyntaxChecker

A SyntaxChecker which verifies that a value is a Jpeg according to RFC 4517. The JFIF (Jpeg File Interchange Format) specify that a jpeg image starts with the following bytes : 0xFF 0xD8 (SOI, Start Of Image) 0xFF 0xE0 (App0) 0xNN 0xNN (Header length) "JFIF\0" (JFIF string with an ending \0) some other bytes which are related to the image. We will check for those 11 bytes, except the length.
