Syntax

public sealed class FilteredBlockIterator : DisposableWrapper

Public NotInheritable Class FilteredBlockIterator
        Inherits DisposableWrapper

public ref class FilteredBlockIterator sealed : public DisposableWrapper

[<SealedAttribute>]
type FilteredBlockIterator = 
    class
        inherit DisposableWrapper
    end

The FilteredBlockIterator type exposes the following members.

Properties

	Name	Description
	AutoDelete	Property that indicates whether the object should be automatically deleted by the Garbage Collector. (Inherited from DisposableWrapper)
	BuffersForComposition	Property that indicates whether the index iterator needs to buffer output if it is not used as the primary index iterator. Default is false. If false, only the first index/filter pair is traversed, with subsequent pairs queried via accepts(). If true, after all the IDs from the previous iterator have been added to the buffer, the start(), next() and id() of this iterator are to be used to iterate through the data.
	EstimatedHitFraction	Property that represents the estimated fraction [0.0 .. 1.0] of the contents that is selected by the Filter query. This property is used to order the FilteredBlockIterator objects during a block traversal. * 0.0 forces the iterator to be used first. * 1.0 forces the iterator to be used last. The filters with the fewest hits will be applied first.
	Id	Property that represents the Object ID of the record currently referenced by this Iterator object.
	IsDisposed	Property that indicates whether pointer to native code unmanaged object == IntPtr::Zero. (Inherited from DisposableWrapper)
	Next	Property that represents the Object ID of the next object, and increments this Iterator object.
	UnmanagedObject	Property that represents a pointer to an unmanaged object. (Inherited from DisposableWrapper)

Methods

	AddToBuffer	Adds the specified Object ID to the buffer of an Index iterator.
	CreateObjRef	(Inherited from MarshalByRefObject)
