SimpleQueryRecord.PartialResult.Step Class

Default constructor (necessary for IPortableObject interface).

Copy constructor for an IStep.

The amount of time (in ms) spent evaluating the filter or applying an index for this query plan step.

The calculated cost of applying the filter as defined by IIndexAwareFilter.CalculateEffectiveness(IDictionary, ICollection).

A description of the filter that was associated with this step during its creation.

The recorded information about the index lookups performed during filter evaluation as part of an IQueryRecord.

The size of the key set remaining after evaluating the filter or applying an index. This value can be used together with PreFilterKeySetSize to calculate an actual effectiveness (reduction of the key set) for this filter step.

The size of the key set prior to evaluating the filter or applying an index. This value can be used together with PostFilterKeySetSize to calculate an actual effectiveness (reduction of the key set) for this filter step.

The inner nested steps, may be null if not nested.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Serves as the default hash function.

Gets the Type of the current instance.

Determine whether or not the given step is capable of being placed in one-to-one correspondence with this step. Steps are defined to be matching if both steps have equivalent name, index lookup records and owned lists of sub-steps.

Creates a shallow copy of the current Object.

Merge the given step with this one. This method assumes that the given step matches with this one.

Restore the contents of a user type instance by reading its state using the specified IPofReader object.

Returns a string that represents the current object.

Save the contents of a POF user type instance by writing its state using the specified IPofWriter object.

The execution time in milliseconds.

The list of child steps.

The estimated cost.

The pre-execution key set size.

The post-execution key set size.

The set of index lookup records.

The filter description.
