Interface Summary

Interface	Description
ComparableIdentifiedDataSerializable	Defines a contract of objects that are simultaneously Comparable and IdentifiedDataSerializable.
Extractable	Enables extracting attribute value from an object, usually from an Entry
Index	Represents an index built on top of the attribute of the map entries.
IndexProvider	Provides storage-specific indexes to Indexes.
IndexStore	Defines a contract for index stores, so different index stores may be used interchangeably with the same Index implementation.
InternalIndex	Provides the private index API.
MultiResultSet	TODO:
QueryContextProvider	Provides query contexts for Indexes to execute queries.

Class Summary

Class	Description
AbstractIndex	Provides an abstract base for indexes.
AndResultSet	And Result set for Predicates.
AttributeIndexRegistry	Maintains a registry of single-attribute indexes.
BaseIndexStore	Base class for concrete index store implementations
CachedQueryEntry<K,V>	Entry of the Query.
Comparables	Provides utilities which compare and canonicalize Comparable instances.
CompositeConverter	Represents a composite converter composed out of a converter tuple.
CompositeValue	Represents a composite value composed out of a value tuple called components.
ConverterCache	Maintains a cache of TypeConverter instances corresponding to attributes of a single Indexes instance.
DefaultArgumentParser	ArgumentParser that's used by default.
DefaultIndexProvider	Provides on-heap indexes.
DefaultValueCollector
DuplicateDetectingMultiResult
FalsePredicate<K,V>	A Predicate which always returns false.
FastMultiResultSet	Multiple result set for Predicates.
GlobalQueryContextProvider	Provides the query context support for global indexes with disabled stats.
GlobalQueryContextProviderWithStats	Provides the query context support for global indexes with enabled stats.
GlobalQueryContextWithStats	Extends the basic query context to support the per-index stats tracking on behalf of global indexes.
Indexes	Contains all indexes for a data-structure, e.g.
Indexes.Builder	Builder which is used to create a new Indexes object.
IndexHeapMemoryCostUtil	Provides utilities useful for on-heap memory cost estimation.
IndexImpl	Provides implementation of on-heap indexes.
IndexInfo
MapIndexInfo
Numbers	Provides utilities which compare and canonicalize Number instances.
OrderedIndexStore	Store indexes rankly.
OrResultSet	Or result set for Predicates.
PartitionQueryContextProvider	Provides the query context support for partitioned indexes with disabled stats.
PartitionQueryContextProviderWithStats	Provides the query context support for partitioned indexes with enabled stats.
PartitionQueryContextWithStats	Extends the basic query context to support the per-index stats tracking on behalf of partitioned indexes.
QueryableEntriesSegment	Holder class for a collection of queried entries and the index from which new items can be fetched.
QueryableEntry<K,V>	This abstract class contains methods related to Queryable Entry, which means searched an indexed by SQL query or predicate.
QueryContext	Provides the context for queries execution.
QueryEntry	Entry of the Query.
SingleResultSet	Multiple result set for Predicates.
SkipIndexPredicate	The SkipIndexPredicate is a predicate that prevents an index from being used on the wrapped predicate.
TypeConverters
TypeConverters.BaseTypeConverter
UnorderedIndexStore	Store indexes out of turn.

Enum Summary

Enum	Description
AttributeType	Type of Attribute
Comparison	Defines comparisons supported by Index.getRecords(Comparison, Comparable) and IndexStore.getRecords(Comparable).
Index.OperationSource	Identifies an original source of an index operation.
IndexCopyBehavior	Defines the behavior for index copying on index read/write.
QueryContext.IndexMatchHint	Defines possible index matching hints.
