AggregationOnColumn<T extends Aggregation>	An Aggregation instance that also holds a column number so the aggregation can be done on a specific column of data in a table.
AggregationOverWindow<T extends Aggregation & RollingAggregation<T>>	An Aggregation instance that also holds a column number and window metadata so the aggregation can be done over a specific window.
ArrowColumnBuilder	Column builder from Arrow data.
ArrowIPCOptions	Options for reading data in Arrow IPC format
ArrowIPCOptions.Builder
ArrowIPCWriterOptions	Settings for writing Arrow IPC data.
ArrowIPCWriterOptions.Builder
BaseDeviceMemoryBuffer	Base class for all MemoryBuffers that are in device memory.
ColumnFilterOptions	Base options class for input formats that can filter columns.
ColumnFilterOptions.Builder<T extends ColumnFilterOptions.Builder>
ColumnVector	This class represents the immutable vector of data.
ColumnVector.OffHeapState	Holds the off heap state of the column vector so we can clean it up, even if it is leaked.
ColumnView	This class represents the column_view of a column analogous to its cudf cpp counterpart.
ContiguousTable	A table that is backed by a single contiguous device buffer.
CSVOptions	Options for reading a CSV file
CSVOptions.Builder
Cuda
Cuda.Event
Cuda.Stream	A class representing a CUDA stream
CudaMemInfo	Represent free and total device memory.
CuFile	JNI wrapper for accessing the cuFile API.
CuFileBuffer	Represents a cuFile buffer.
CuFileReadHandle	Represents a cuFile file handle for reading.
CuFileWriteHandle	Represents a cuFile file handle for reading.
DeviceMemoryBuffer	This class represents data in some form on the GPU.
DeviceMemoryBufferView	This class represents data in some form on the GPU.
DType
GatherMap	This class tracks the data associated with a gather map, a buffer of INT32 elements that index a source table and can be passed to a table gather operation.
GroupByOptions	Options for groupby (see cudf::groupby::groupby's constructor)
GroupByOptions.Builder
HostColumnVector	Similar to a ColumnVector, but the data is stored in host memory and accessible directly from the JVM.
HostColumnVector.BasicType
HostColumnVector.Builder
HostColumnVector.ColumnBuilder	Build
HostColumnVector.DataType
HostColumnVector.ListType
HostColumnVector.StructData
HostColumnVector.StructType
HostColumnVectorCore	A class that holds Host side Column Vector APIs and the OffHeapState.
HostColumnVectorCore.OffHeapState	Holds the off heap state of the column vector so we can clean it up, even if it is leaked.
HostMemoryBuffer	This class holds an off-heap buffer in the host/CPU memory.
JCudfSerialization	Serialize and deserialize CUDF tables and columns using a custom format.
JCudfSerialization.HostConcatResult	Class to hold the header and buffer pair result from host-side concatenation
JCudfSerialization.SerializedColumnHeader	Holds the metadata about a serialized column.
JCudfSerialization.SerializedTableHeader	Holds the metadata about a serialized table.
JCudfSerialization.TableAndRowCountPair	Holds the result of deserializing a table.
JSONOptions	Options for reading in JSON encoded data.
JSONOptions.Builder
MemoryBuffer	Abstract class for representing the Memory Buffer NOTE: MemoryBuffer is public to make it easier to work with the class hierarchy, subclassing beyond what is included in CUDF is not recommended and not supported.
MemoryBuffer.MemoryBufferCleaner
MemoryCleaner	ColumnVectors may store data off heap, and because of complicated processing the life time of an individual vector can vary a lot.
MemoryCleaner.Cleaner	API that can be used to clean up the resources for a vector, even if there was a leak
