| DefaultSourceIterator | |
| ExecutorParamWriter | An ExecutorParamWriter is a ParamWriter whose scope is limited to a single executor node - it will never be serialized for transfer to a different node. As a result, any object which is allocated from a Vertica memory pool (i.e. a ServerInterface's allocator object) can have its address saved in the ExecutorParamWriter (see setPointer()), and be safely retrieved later on (see getPointer()) from a different API call in the same query |
| ExecutorPlanContext | An ExecutorPlanContext is a PlanContext object whose scope is limited to a single executor node: it and its parameters will never be serialized. In addition to providing information about nodes involved in a query, it indicates how many threads are available and allocated for a load |
| FilterFactory | Produces and initializes UDFilters to transform input data before parsing |
| FIunion | |

| NodeSpecifyingPlanContext | Interface that allows storage of query-plan state, when different parts of query planning take place on different computers |
| ParallelismInfo | |
| ParamReader | Provides read access to a set of named parameters. This class provides type-specific methods to retrieve values |
| ParamWriter | Provides write access to a set of named parameters. This class extends ParamReader to add type-specific methods to write values |
| ParserFactory | Produces and initializes UDParsers to parse input into tuples |
| PartitionOrderColumnInfo | Represents the partition by and order by column information for each phase in a multi-phase transform function |
| PartitionReader | Iterator-based read interface over all input data in a single partition. Automatically fetches data a block-at-a-time, as needed |
| PartitionWriter | Provides an iterator-based write interface over output data for a single partition. Automatically makes space a block-at-a-time, as needed |
| PartitionWriterColumn | |
| PartitionWriterColumns | PartitionWriterColumns allow column-by-column access to PartitionWriter data |
| PartitionWriterNumericColumn | |
| PartitionWriterStringColumn | |
| PartitionWriterUuidColumn | |
| PerColumnParamReader | A wrapper around a map from column to ParamReader |
| PlanContext | Shared query-plan state, used when different parts of query planning take place on different nodes. For example, if some work is done on the query initiator node and some is done on each node executing the query, this class stores shared state |
| Portion | |
| RejectedRecord | |
| ScalarFunction | Interface for User-Defined Scalar Function (UDSF). A UDSF produces a single value from a row of data |
| ScalarFunctionFactory | Interface for declaring parameters and return types for, and instantiating, an associated ScalarFunction |
| ScopedTimerCounter | Class to start an execution timer on construction and to automatically stop the timer on deconstruction or when manually called with stop() |
| ServerInterface | Provides UDxs with access to the Vertica server |
| FunctionDescription | |
| RelationDescription | |
| TypeDescription | |
| SessionParamReaderMap | This class provides an interface for reading the Used defined session parameters |
| SessionParamWriterMap | This class provides an interface for writing the Used defined session parameters |
| SizedColumnTypes | Represents types and information to determine the size of the columns as input/output of a User Defined Function/Transform |

| SourceFactory | Produces and initializes UDSources to process input data sources |
| SourceIterator | Constructs a set of Sources to be used by an IterativeSourceFactory |
| StreamWriter | Provides an iterator-based write interface over output data for a stream of blocks. Automatically makes space a block-at-a-time, as needed |
| TransformFunction | Interface for User-Defined Transform Function (UDTF). A UDTF operates on a table segment and returns zero or more rows of data |
| TransformFunctionFactory | Interface for declaring parameters and return types for, and instantiating, an associated TransformFunction |
| TransformFunctionPhase | Interface to provide compile-time information for a single phase of a multi-phase user-defined transform function |
| UDChunker | Separates parser input into chunks at record boundaries, allowing parsing to proceed in parallel |
