public class SafeComparer : IQueryCacheComparer, IEntryAwareComparer, IComparer, IPortableObject
The SafeComparer type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SafeComparer |
Default constructor.
|
| SafeComparer(IComparer) |
Construct a SafeComparer delegating to the specified (wrapped)
comparer.
|
Properties
Methods| Name | Description | |
|---|---|---|
| Compare |
Compares its two arguments for order.
|
| CompareEntries |
Compare two entries based on the rules specified by IComparer.
|
 | CompareSafe |
Compares its two arguments for order.
|
| Equals |
Determine if two comparers are equal.
(Overrides ObjectEquals(Object).) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode |
Return the hash code for this comparator.
(Overrides ObjectGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsKeyComparer |
Specifies whether this comparer expects to compare keys or
values.
|
| IsKeyComparer(IComparer) |
Check whether the specified comparer expects to compare keys or
values.
|
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadExternal |
Restore the contents of a user type instance by reading its state
using the specified IPofReader object.
|
| ToString |
Returns a human-readable description for this IComparer.
(Overrides ObjectToString.) |
| WriteExternal |
Save the contents of a POF user type instance by writing its
state using the specified IPofWriter object.
|
Fields| Name | Description | |
|---|---|---|
 | Instance |
The trivial SafeComparer.
|
 | m_comparer |
The wrapped IComparer.
|
Remarksnull values are evaluated as "less then" any non-null value. If the wrapped comparator is not specified then all non-null values must implement the IComparable interface.
Use SafeComparer.Instance to obtain an instance of non-delegating SafeComparer.
