Class DefaultAttributeValidationPolicy

java.lang.Object
  org.springframework.ldap.ldif.support.DefaultAttributeValidationPolicy

All Implemented Interfaces:

AttributeValidationPolicy

public class DefaultAttributeValidationPolicy
extends Object
implements AttributeValidationPolicy

Ensures the buffer represents a valid attribute as defined by RFC2849. Meets the standards imposed by RFC 2849 for the "LDAP Data Interchange Format (LDIF) - Technical Specification". Special attention is called to URL support: RFC 2849 requires that LDIFs support URLs as defined in 1738; however, RFC 1738 has been updated by several RFCs including RFC 1808, RFC 2396, and RFC 3986 (which obsoleted the formers). Unsupported features of this implementation of URL identification include query strings and fragments in HTTP URLs.
