PersistentObjectFieldFilterCollection Class |
Namespace: Obujekutoru
The PersistentObjectFieldFilterCollection type exposes the following members.
Name | Description | |
---|---|---|
And(PersistentObjectFieldFilter) |
Adds a persistent object field filter to an existing collection.
| |
And(String, PersistentObjectFieldFilterOperator, Object) |
Adds a persistent object field filter to an existing collection.
| |
Empty |
Builds an empty collection of persistent object field filters.
| |
Equals | (Inherited from Object.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |
