Class Summary

Class	Description
Aggregate	Class for all the aggregate functions like count, max etc
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.
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.
DeviceMemoryBuffer	This class represents data in some form on the GPU.
DeviceMemoryBufferView	This class represents data in some form on the GPU.
GroupByOptions	Options for group by (see cudf::groupby::Options)
GroupByOptions.Builder
HostColumnVector	Similar to a ColumnVector, but the data is stored in host memory and accessible directly from the JVM.
HostColumnVector.Builder	Build
HostColumnVector.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.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
NativeDepsLoader	This class will load the native dependencies.
NvtxRange	Utility class to mark an NVTX profiling range.
ORCOptions	Options for reading a ORC file
ORCOptions.Builder
ORCWriterOptions
ORCWriterOptions.Builder
ParquetOptions	Options for reading a parquet file
ParquetOptions.Builder
ParquetWriterOptions	Settings for writing Parquet files.
ParquetWriterOptions.Builder
PartitionedTable	Class to provide a PartitionedTable
PinnedMemoryPool	This provides a pool of pinned memory similar to what RMM does for device memory.
Range	Helper utility for creating ranges.
Rmm	This is the binding class for rmm lib.
Rmm.LogConf	What to send RMM alloc and free logs to.
RmmAllocationMode
Scalar	A single scalar value.
Schema	The schema of data to be read in.
Schema.Builder
Table	Class to represent a collection of ColumnVectors and operations that can be performed on them collectively.
Table.AggregateOperation	Class representing aggregate operations
Table.OrderByArg
Table.TableOperation
Table.TestBuilder	Create a table on the GPU with data from the CPU.
WindowAggregate	Spec for window-based aggregation (for analytical functions)
WindowAggregateOp	Operator for window-based aggregation (for analytical functions).
WindowOptions	Options for rolling windows.
WindowOptions.Builder
