public class DitStructureRule
extends AbstractSchemaObject

A dITStructureRule definition. A dITStructureRules is a rule governing the structure of the DIT by specifying a permitted superior to subordinate entry relationship. A structure rule relates a nameForm, and therefore a STRUCTURAL objectClass, to superior dITStructureRules. This permits entries of the STRUCTURAL objectClass identified by the nameForm to exist in the DIT as subordinates to entries governed by the indicated superior dITStructureRules. Hence dITStructureRules only apply to structural object classes.

According to ldapbis [MODELS]:

  DIT structure rule descriptions are written according to the ABNF:
  
    DITStructureRuleDescription = LPAREN WSP
        ruleid                    ; rule identifier
        [ SP "NAME" SP qdescrs ]  ; short names (descriptors)
        [ SP "DESC" SP qdstring ] ; description
        [ SP "OBSOLETE" ]         ; not active
        SP "FORM" SP oid          ; NameForm
        [ SP "SUP" ruleids ]      ; superior rules
        extensions WSP RPAREN     ; extensions
 
    ruleids = ruleid / ( LPAREN WSP ruleidlist WSP RPAREN )
 
    ruleidlist = ruleid *( SP ruleid )
 
    ruleid = number
 
  where:
    [ruleid] is the rule identifier of this DIT structure rule;
    NAME [qdescrs] are short names (descriptors) identifying this DIT
        structure rule;
    DESC [qdstring] is a short descriptive string;
    OBSOLETE indicates this DIT structure rule use is not active;
    FORM is specifies the name form associated with this DIT structure
        rule;
    SUP identifies superior rules (by rule id); and
    [extensions] describe extensions.
  
  If no superior rules are identified, the DIT structure rule applies
  to an autonomous administrative point (e.g. the root vertex of the
  subtree controlled by the subschema) [X.501].

Field Detail

serialVersionUID

public static final long serialVersionUID

The mandatory serialVersionUID

See Also:

Constant Field Values

ruleId

private int ruleId

The rule ID. A DSR does not have an OID

form

private String form

The associated NameForm

superRules

private List<Integer> superRules

The list of superiors rules

Constructor Detail

DitStructureRule

public DitStructureRule(int ruleId)

Creates a new instance of DitStructureRule

Parameters:

ruleId - The RuleId for this DitStructureRule

Method Detail

getForm

public String getForm()

Returns:

The associated NameForm's OID

setForm

public void setForm(String form)

Sets the associated NameForm's OID

Parameters:

form - The NameForm's OID

getRuleId

public int getRuleId()

Returns:

The Rule ID

setRuleId

public void setRuleId(int ruleId)

Sets the rule identifier of this DIT structure rule;

Parameters:

ruleId - the rule identifier of this DIT structure rule;

getSuperRules

public List<Integer> getSuperRules()

Returns:

The list of superiors RuleIDs

setSuperRules

public void setSuperRules(List<Integer> superRules)

Sets the list of superior RuleIds

Parameters:

superRules - the list of superior RuleIds

addSuperRule

public void addSuperRule(Integer superRule)

Adds a new superior RuleId

Parameters:

superRule - The superior RuleID to add

getOid

public String getOid()

The DIT structure rule does not have an OID Gets usually what is the numeric object identifier assigned to this SchemaObject. All schema objects except for MatchingRuleUses have an OID assigned specifically to then. A MatchingRuleUse's OID really is the OID of it's MatchingRule and not specific to the MatchingRuleUse. This effects how MatchingRuleUse objects are maintained by the system.

Specified by:

getOid in interface SchemaObject

Overrides:

getOid in class AbstractSchemaObject

Returns:

an OID for this SchemaObject or its MatchingRule if this SchemaObject is a MatchingRuleUse object

toString

public String toString()

Overrides:

toString in class Object

copy

public DitStructureRule copy()

Copy the current SchemaObject on place

Returns:

The copied SchemaObject

hashCode

public int hashCode()

Description copied from class: AbstractSchemaObject

Specified by:

hashCode in interface SchemaObject

Overrides:

hashCode in class AbstractSchemaObject

See Also:

Object.equals(Object)

equals

public boolean equals(Object o)

Specified by:

equals in interface SchemaObject

Overrides:

equals in class AbstractSchemaObject

clear

public void clear()

Clear the current SchemaObject : remove all the references to other objects, and all the Maps.

Specified by:

clear in interface SchemaObject

Overrides:

clear in class AbstractSchemaObject
