Looks up a specific class definition and returns it in raw (unexpanded) form.

A class in raw form lists only those attribute and class rules specified directly by the class, not the inherited ones.

Use this function as a generic replacement for getUnexpandedClassDefinition which was originally coded to return an NDSClassDefinition.

Parameters:

className - The name of the class to look up.

Returns:

A valid LDAPClassDefinition in unexpanded form.

Throws:

NamespaceException - Class is not defined.

public final boolean isClassDefined(java.lang.String className)

Determines if a given class is defined.

Parameters:

className - The name of the class to check. This may be the standard name or an alias name.

Returns:

True if the class is defined, false otherwise.

isAttributeDefined

public final boolean isAttributeDefined(java.lang.String attrName)

Determines if an attribute is defined.

Parameters:

attrName - The name of the attribute to check.

Returns:

True if the attribute is defined, false otherwise.

getSubClasses

public ClassDefinition[] getSubClasses(java.lang.String className)

Retrieve ALL classes which derive from a specific class type.

The class definitions returned are in expanded form.

Parameters:

className - Name of the super class.

Returns:

The class definitions returned are in unexpanded form. This routine was kept for backward compatibility. You can get the complete list as a String array with: getClassDefinition(className).getSuperClasses();

Parameters:

className - The name of the subclass.

Returns:

An array of unexpanded ClassDefinition objects representing the super classes.

Throws:

NamespaceException - Thrown if the class is not defined in schema.

An array of AttributeDefinition objects representing the mandatory attributes of the specified class.

Throws:

NamespaceException - Thrown if the class is not defined in the schema.

translateAliasAttributeName

public java.lang.String translateAliasAttributeName(java.lang.String oldName)

Returns:

The offical attribute name, or the original string if it's not an alias.

translateAliasClassName

public java.lang.String translateAliasClassName(java.lang.String oldName)
