Class Summary

Class	Description
AbstractCloseableIterator<T>	An abstract that Iterator helps implement an non-removable CloseableIterator.
AbstractDataset	Handy abstract implementation of Dataset that acts on a list of underlying datasets and implements TransactionAware and MeteredDataset interfaces by propagating corresponded logic to each dataset in a list when possible.
AbstractDatasetDefinition<D extends Dataset,A extends DatasetAdmin>	Basic abstract implementation of DatasetDefinition.
CompositeDatasetAdmin	Implementation of DatasetAdmin that propagates administrative operations to the given list of DatasetAdmins
CompositeDatasetDefinition<D extends Dataset>	Handy implementation of DatasetDefinition that implements basic methods by delegating logic execution to underlying dataset definitions.
ConditionCodec	Codec used to serialize and deserialize PartitionFilter.Conditions.
CounterTimeseriesTable	Deprecated table based datasets will be removed in a future version
CounterTimeseriesTable.Counter	Defines an object for counters in CounterTimeseriesTable.
CounterTimeseriesTableDefinition	DatasetDefinition for CounterTimeseriesTable.
DynamicPartitioner<K,V>	Responsible for dynamically determining a @{link PartitionKey}.
FileSetArguments	Constants and helper methods to configure runtime arguments for a file dataset.
FileSetProperties	Helper to build properties for files datasets.
FileSetProperties.Builder	A Builder to construct properties for FileSet datasets.
IndexedObjectStore<T>	Deprecated table based datasets will be removed in a future version
IndexedObjectStoreDefinition	DatasetDefinition for IndexedObjectStore.
IndexedTable	Deprecated table based datasets will be removed in a future version
IndexedTableDefinition	DatasetDefinition for IndexedTable.
KeyValue<KEY_TYPE,VALUE_TYPE>	Represents key value pair
KeyValueTable	Deprecated table based datasets will be removed in a future version
KeyValueTableDefinition	DatasetDefinition for KeyValueTable.
ObjectMappedTableProperties	Helper to build properties for an ObjectMappedTable.
ObjectMappedTableProperties.Builder	A Builder to construct properties for ObjectMappedTable datasets.
ObjectStores	Utility for describing ObjectStore and similar datasets within application configuration.
PartitionConsumerResult	Returns access to an iterator of the requested partitions as well as a PartitionConsumerState which can be used to request partitions created after the previous request of partitions.
PartitionConsumerState	Contains the state necessary to keep track of which partitions are processed and which partitions would need to be processed as they are created.
PartitionedFileSetArguments	Helpers for manipulating runtime arguments of time-partitioned file sets.
PartitionedFileSetProperties	Helper to build properties for files datasets.
PartitionedFileSetProperties.Builder	A Builder to construct properties for FileSet datasets.
PartitionFilter	Describes a filter over partition keys.
PartitionFilter.Builder	A builder for partition filters.
PartitionFilter.Condition<T extends Comparable<T>>	Represents a condition on a partitioning field, by means of an inclusive lower bound and an exclusive upper bound.
Partitioning	This class describes how a dataset is partitioned, by means of the fields of a partition key and their types.
Partitioning.Builder	A builder for partitioning objects.
PartitionKey	Types and methods to specify partitioning keys for datasets.
PartitionKey.Builder	A builder for partitioning objects.
PartitionMetadata	Contains metadata associated with a particular Partition of a PartitionedFileSet.
TimePartitionedFileSetArguments	Helpers for manipulating runtime arguments of time-partitioned file sets.
TimeseriesTable	Deprecated table based datasets will be removed in a future version
TimeseriesTable.Entry	Time series table entry.
TimeseriesTable.InputSplit	A method for using a Dataset as input for a MapReduce job.
TimeseriesTableDefinition	DatasetDefinition for TimeseriesTable.
TimeseriesTables	Utility for describing TimeseriesTable data set within application configuration.

Enum Summary

Enum	Description
