Properties| Name | Description | |
|---|---|---|
 | Value |
Gets the object to compare the extraction result with.
(Inherited from ComparisonFilter.) |
| ValueExtractor |
Obtain the IValueExtractor used by this filter.
(Inherited from ExtractorFilter.) |
Methods| Name | Description | |
|---|---|---|
| ApplyIndex |
Filter remaining keys using an IDictionary of available indexes.
|
| CalculateEffectiveness |
Given an IDictionary of available indexes, determine if this
IIndexAwareFilter can use any of the indexes to assist in its
processing, and if so, determine how effective the use of that
index would be.
|
 | CalculateMatchEffectiveness |
Helper method to calculate effectiveness for ComparisonFilters that
need no more than a single index match in order to retrieve all
necessary keys to perform the applyIndex() operation.
Such filters are: Contains, Equals, NotEquals.
(Inherited from ComparisonFilter.) |
| CalculateRangeEffectiveness |
Helper method to calculate effectiveness for ComparisonFilters that
need a range of values from an index in order to retrieve all
necessary keys to perform the applyIndex() operation.
Such filters are: Less, LessEquals, Greater, GreaterEquals.
(Inherited from ComparisonFilter.) |
| Equals |
Compare the ComparisonFilter with another object to
determine equality.
(Inherited from ComparisonFilter.) |
| Evaluate |
Apply the test to the object.
(Inherited from ExtractorFilter.) |
| EvaluateEntry |
Apply the test to an ICacheEntry.
(Inherited from ExtractorFilter.) |
| EvaluateExtracted |
Evaluate the specified extracted value.
(Overrides ExtractorFilterEvaluateExtracted(Object).) |
| Extract |
Gets the result of IValueExtractor invocation.
(Inherited from ExtractorFilter.) |
| 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 |
Determine a hash value for the ComparisonFilter object
according to the general object.GetHashCode() contract.
(Inherited from ComparisonFilter.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| 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.
(Inherited from ComparisonFilter.) |
| ToString |
Return a human-readable description for this
ComparisonFilter.
(Inherited from ComparisonFilter.) |
| WriteExternal |
Save the contents of a POF user type instance by writing its
state using the specified IPofWriter object.
(Inherited from ComparisonFilter.) |
Fields| Name | Description | |
|---|---|---|
 | m_extractor |
The ValueExtractor used by this filter.
(Inherited from ExtractorFilter.) |
| m_value |
The value to compare to.
(Inherited from ComparisonFilter.) |
Remarks
In a case when either result of a member invocation or a value to
compare are equal to null, the Evaluate test yields
false. This approach is equivalent to the way the null
values are handled by SQL.
