The GroupAggregator type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | GroupAggregator()()()() |
Default constructor.
|
 | GroupAggregator(IValueExtractor, IEntryAggregator, IFilter) |
Construct a GroupAggregator based on a specified
IValueExtractor and underlying
IEntryAggregator.
|
Methods
| Name | Description | |
|---|---|---|
| Aggregate |
Process a collection of IInvocableCacheEntry
objects using the underlying extractor to split the entries
into non-intersecting (distinct) groups and then apply the
underlying aggregator separately to each group.
|
 | CreateInstance(String, IEntryAggregator) |
Create an instance of GroupAggregator based on a specified member
name(s) and an IEntryAggregator.
|
| CreateInstance(IValueExtractor, IEntryAggregator) |
Create an instance of GroupAggregator based on a specified
extractor and an IEntryAggregator.
|
| CreateInstance(String, IEntryAggregator, IFilter) |
Create an instance of GroupAggregator based on a specified member
name(s), an IEntryAggregator and a result
evaluation filter.
|
| CreateInstance(IValueExtractor, IEntryAggregator, IFilter) |
Create an instance of GroupAggregator based on a specified
extractor and an IEntryAggregator and a result
evaluation filter.
|
| Equals |
Compare the GroupAggregator with another object to determine
equality.
(Overrides Object..::..Equals(Object).) |
| Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode |
Determine a hash value for the GroupAggregator object according
to the general object.GetHashCode() contract.
(Overrides Object..::..GetHashCode()()()().) |
| 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.
|
| ToString |
Return a human-readable description for this GroupAggregator.
(Overrides Object..::..ToString()()()().) |
| WriteExternal |
Save the contents of a POF user type instance by writing its
state using the specified IPofWriter object.
|
Fields
| Name | Description | |
|---|---|---|
 | m_aggregator |
The underlying IEntryAggregator.
|
| m_extractor |
The underlying IValueExtractor.
|
| m_filter |
The IFilter object representing the "having" clause of this
"group by" aggregator.
|
Properties
| Name | Description | |
|---|---|---|
 | Aggregator |
Obtain the underlying IEntryAggregator.
|
| Extractor |
