| CVertica::UDParser | Parses an input stream into Vertica tuples (rows to be inserted into a table) |
| ▶CVertica::UDXFunction | |
| CVertica::AggregateFunction | Interface for User-Defined Aggregate Function (UDAF). A UDAF operates on one column of data and returns one column of data |
| CVertica::AnalyticFunction | Interface for User-Defined Analytic Function (UDAnF). A UDAnF operates on rows of data and returns rows of data, not necessarily 1:1 |
| CVertica::ScalarFunction | Interface for User-Defined Scalar Function (UDSF). A UDSF produces a single value from a row of data |
| CVertica::TransformFunction | Interface for User-Defined Transform Function (UDTF). A UDTF operates on a table segment and returns zero or more rows of data |

Use, with IterativeSourceFactory, if computing the size of a source up front would be prohibitively expensive, or if the number of distinct sources would be prohibitively large to use the standard API. Typically you should use UDSource instead |

| CVertica::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 |
