The ContainsFilter type exposes the following members.
Constructors

|---|---|---|
| ContainsFilter | Overloaded. |
Methods
| Name | Description | |
|---|---|---|
| ApplyIndex |
Filter remaining keys using an IDictionary of available indexes.
The filter is responsible for removing all keys from the passed
set of keys that the applicable indexes can prove should be
filtered. If the filter does not fully evaluate the remaining
keys using just the index information, it must return a filter
that can complete the task using an iterating implementation.
If, on the other hand, the filter does fully evaluate the
remaining keys using just the index information, then it should
return null to indicate that no further filtering is
necessary.

| 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.
The returned value is an effectiveness estimate of how well this
filter can use the specified indexes to filter the specified
keys.
An operation that requires no more than a single access to the
index content (i.e. Equals, NotEquals) has an effectiveness of
one. Evaluation of a single entry is assumed to have an
effectiveness that depends on the index implementation and is
usually measured as a constant number of the single operations.
This number is referred to as evaluation cost.
If the effectiveness of a filter evaluates to a number larger
than the keys.size() then a user could avoid using the index and
iterate through the keys calling evaluate rather than
applyIndex.

| 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.
