ConditionalExtractor Class |
14c (14.1.1.0)
F23534-02
An IndexAwareExtractor implementation that is only used to create a
ConditionalIndex.
The underlying IValueExtractor is used for value extraction during index creation and is the extractor that is associated with the created ConditionalIndex in the given index map. Using the ConditionalExtractor to extract values in not supported.

SyntaxC#
public class ConditionalExtractor : AbstractExtractor, IIndexAwareExtractor, IValueExtractor, IPortableObject
The ConditionalExtractor type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ConditionalExtractor |
Construct the ConditionalExtractor.
|
| ConditionalExtractor(IFilter, IValueExtractor, Boolean) |
Construct the ConditionalExtractor.
|
Properties| Name | Description | |
|---|---|---|
 | Extractor |
The underlying extractor.
|
| Filter |
The filter used by this extractor.
|
| IsForwardIndexSupported |
Specifies whether or not this extractor will create a
ConditionalIndex that supports a forward index.
|
 | Target |
The target of the extractor.
(Inherited from AbstractExtractor.) |
Methods| Name | Description | |
|---|---|---|
| Compare |
Compares its two arguments for order.
(Inherited from AbstractExtractor.) |
| CompareEntries |
Compare two entries.
(Inherited from AbstractExtractor.) |
| CreateIndex |
Create an index and associate it with the corresponding extractor.
Important: it is a responsibility of this method's implementations to place the necessary <IValueExtractor, ICacheEntry> entry into the given map of indexes. |
| DestroyIndex |
Destroy an existing index and remove it from the given dictionary
of indexes.
|
| Equals |
Compare the ConditionalExtractor with another object to determine
equality.
(Overrides ObjectEquals(Object).) |
| Extract |
Using a ConditionalExtractor to extract values is not supported.
(Overrides AbstractExtractorExtract(Object).) |
| ExtractFromEntry |
Extract the value from the passed Entry object. The returned
value should follow the conventions outlined in the
Extract(Object) method.
(Inherited from AbstractExtractor.) |
| ExtractOriginalFromEntry |
Extract the value from the "original value" of the passed
CacheEntry object or the key (if targeted). This method's conventions are exactly the same
as the ExtractFromEntry(ICacheEntry) method.
(Inherited from AbstractExtractor.) |
 | 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 ConditionalExtractor object
according to the general Object.GetHashCode contract.
(Overrides ObjectGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadExternal |
Deserialize model using specified reader.
|
| ToString |
Return a human-readable description for this ConditionalExtractor.
(Overrides ObjectToString.) |
| WriteExternal |
Save the contents of a POF user type instance by writing its
state using the specified IPofWriter object.
|
Fields| Name | Description | |
|---|---|---|
 | m_target |
Specifies which part of the entry should be used by the
ExtractFromEntry(ICacheEntry) operation. Legal values are
VALUE (default) or KEY.
(Inherited from AbstractExtractor.) |
