  • Method Details

    • getOID

      @NotNull public String getOID()
      Retrieves the OID for this object class.
      Returns:
      The OID for this object class.

    • getNames

      @NotNull public String[] getNames()
      Retrieves the set of names for this object class.
      Returns:
      The set of names for this object class, or an empty array if it does not have any names.

    • getNameOrOID

      @NotNull public String getNameOrOID()
      Retrieves the primary name that can be used to reference this object class. If one or more names are defined, then the first name will be used. Otherwise, the OID will be returned.
      Returns:
      The primary name that can be used to reference this object class.

    • hasNameOrOID

      public boolean hasNameOrOID(@NotNull String s)
      Indicates whether the provided string matches the OID or any of the names for this object class.
      Parameters:
      s - The string for which to make the determination. It must not be null.
      Returns:
      true if the provided string matches the OID or any of the names for this object class, or false if not.

    • getDescription

      @Nullable public String getDescription()
      Retrieves the description for this object class, if available.
      Returns:
      The description for this object class, or null if there is no description defined.

    • isObsolete

      public boolean isObsolete()
      Indicates whether this object class is declared obsolete.
      Returns:
      true if this object class is declared obsolete, or false if it is not.

    • getSuperiorClasses

      @NotNull public String[] getSuperiorClasses()
      Retrieves the names or OIDs of the superior classes for this object class, if available.
      Returns:
      The names or OIDs of the superior classes for this object class, or an empty array if it does not have any superior classes.

    • getSuperiorClasses

      @NotNull public Set<ObjectClassDefinition> getSuperiorClasses(@NotNull Schema schema, boolean recursive)
      Retrieves the object class definitions for the superior object classes.
      Parameters:
      schema - The schema to use to retrieve the object class definitions.
      recursive - Indicates whether to recursively include all of the superior object class definitions from superior classes.
      Returns:
      The object class definitions for the superior object classes.

    • getObjectClassType

      @Nullable public ObjectClassType getObjectClassType()
      Retrieves the object class type for this object class. This method will return null if this object class definition does not explicitly specify the object class type, although in that case, the object class type should be assumed to be ObjectClassType.STRUCTURAL as per RFC 4512 section 4.1.1.
      Returns:
      The object class type for this object class, or null if it is not defined in the schema element.

    • getObjectClassType

      @NotNull public ObjectClassType getObjectClassType(@NotNull Schema schema)
      Retrieves the object class type for this object class, recursively examining superior classes if necessary to make the determination.

      Note that versions of this method before the 4.0.6 release of the LDAP SDK operated under the incorrect assumption that if an object class definition did not explicitly specify the object class type, it would be inherited from its superclass. The correct behavior, as per RFC 4512 section 4.1.1, is that if the object class type is not explicitly specified, it should be assumed to be ObjectClassType.STRUCTURAL.
      Parameters:
      schema - The schema to use to retrieve the definitions for the superior object classes. As of LDAP SDK version 4.0.6, this argument is no longer used (and may be null if desired), but this version of the method has been preserved both for the purpose of retaining API compatibility with previous versions of the LDAP SDK, and to disambiguate it from the zero-argument version of the method that returns null if the object class type is not explicitly specified.
      Returns:
      The object class type for this object class, or ObjectClassType.STRUCTURAL if it is not explicitly defined.

    • getRequiredAttributes

      @NotNull public String[] getRequiredAttributes()
      Retrieves the names or OIDs of the attributes that are required to be present in entries containing this object class. Note that this will not automatically include the set of required attributes from any superior classes.
      Returns:
      The names or OIDs of the attributes that are required to be present in entries containing this object class, or an empty array if there are no required attributes.

    • getRequiredAttributes

      @NotNull public Set<AttributeTypeDefinition> getRequiredAttributes(@NotNull Schema schema, boolean includeSuperiorClasses)
      Retrieves the attribute type definitions for the attributes that are required to be present in entries containing this object class, optionally including the set of required attribute types from superior classes.
      Parameters:
      schema - The schema to use to retrieve the attribute type definitions.
      includeSuperiorClasses - Indicates whether to include definitions for required attribute types in superior object classes.
      Returns:
      The attribute type definitions for the attributes that are required to be present in entries containing this object class.

    • getOptionalAttributes

      @NotNull public String[] getOptionalAttributes()
      Retrieves the names or OIDs of the attributes that may optionally be present in entries containing this object class. Note that this will not automatically include the set of optional attributes from any superior classes.
      Returns:
      The names or OIDs of the attributes that may optionally be present in entries containing this object class, or an empty array if there are no optional attributes.

    • getOptionalAttributes

      @NotNull public Set<AttributeTypeDefinition> getOptionalAttributes(@NotNull Schema schema, boolean includeSuperiorClasses)
      Retrieves the attribute type definitions for the attributes that may optionally be present in entries containing this object class, optionally including the set of optional attribute types from superior classes.
      Parameters:
      schema - The schema to use to retrieve the attribute type definitions.
      includeSuperiorClasses - Indicates whether to include definitions for optional attribute types in superior object classes.
      Returns:
      The attribute type definitions for the attributes that may optionally be present in entries containing this object class.

    • getExtensions

      @NotNull public Map<String,String[]> getExtensions()
      Retrieves the set of extensions for this object class. They will be mapped from the extension name (which should start with "X-") to the set of values for that extension.
      Returns:
      The set of extensions for this object class.

    • getSchemaElementType

      @NotNull public SchemaElementType getSchemaElementType()

      getSchemaElementType in class SchemaElement
      Returns:

    • hashCode

      public int hashCode()
