public abstract class AttributeDatabaseBase : IAttributeDatabase
The AttributeDatabaseBase type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | AttributeDatabaseBase | Initializes a new instance of the AttributeDatabaseBase class |
Properties| Name | Description | |
|---|---|---|
 | NumAttributes |
The number of attributes.
|
Methods| Name | Description | |
|---|---|---|
 | CreateValue |
Create an attribute value of the specified dimensions.
|
| FindAddOrUpdateAttributeValue |
Find, add or update an attribute value.
If an attribute value with the specified id does not exist, then the function 'create' is called to create a new attribute value. If the 'create' function is null then no new attribute value is added. If an attribute value with the specified id already exists, then the function 'update' (if not null) is called to update the attribute value. |
| GetAttributeValues |
Get all the attribute values.
