| Classification::Classification | ( | $ClassId, | |

Class constructor.
This can be used both to access an existing classification or to add a new classification to a hierarchy. For existing classifications specify just the Classification ID. For new classifications, pass in NULL for the Classification ID, and specify all of the other parameters.
| int | null | $ClassId | ID of Classification. Use NULL to create a new Classification. |
| string | $Name | Full name or segment name for new Classification. Segment name can be used if a parent ID is also supplied, otherwise full name is assumed. (OPTIONAL) |
| int | $FieldId | MetadataField ID for new Classification. (OPTIONAL) |
| int | $ParentId | ID of parent in hierachy of for new Classification. Use -1 for new Classification with no parent (i.e. at top level of hierarchy). (OPTIONAL) |

| bool | $DeleteParents | Flag indicating whether to also delete Classification entries above this one in the hierarchy. (OPTIONAL

| bool | $DeleteIfHasResources | Flag indicating whether to delete the Classification if it still has Resources associated with it. (OPTIONAL - defaults to FALSE) |
