- - ### Uses of LowLevelIterator in org.apache.uima.cas.impl

    Classes in org.apache.uima.cas.impl that implement LowLevelIterator
    Modifier and Type | Class and Description
    --- | ---
    `class` | `FsIterator_multiple_indexes<T extends FeatureStructure>` Common code for both aggregation of indexes (e.g.
    `class` | `FsIterator_singletype<T extends FeatureStructure>`
    `class` | `FsIterator_subtypes_ordered<T extends FeatureStructure>` Performs an ordered iteration among a set of iterators, each one corresponding to the type or subtype of the uppermost type.
    `class` | `FsIterator_subtypes_snapshot<T extends FeatureStructure>`
    `class` | `FSIteratorImplBase<T extends FeatureStructure>` Version 2 compatibility only, not used internally in version 3 Base class for FSIterator implementations.
    `class` | `LLUnambiguousIteratorImpl<T extends FeatureStructure>` Implements a low level ambiguous or unambiguous iterator over some type T which doesn't need to be a subtype of Annotation.
    `class` | `LowLevelIterator_empty<T extends FeatureStructure>` An empty Low-level FS iterator
    `class` | `Subiterator<T extends AnnotationFS>` Subiterator implementation.

    Fields in org.apache.uima.cas.impl declared as LowLevelIterator
    Modifier and Type | Field and Description

    `static LowLevelIterator<FeatureStructure>` | LowLevelIterator.`FS_ITERATOR_LOW_LEVEL_EMPTY` an empty iterator
    `protected LowLevelIterator<T>[]` | FsIterator_multiple_indexes.`nonEmptyIterators`

    Methods in org.apache.uima.cas.impl that return LowLevelIterator
