CExecutorParamWriter 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
CExecutorPlanContext 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
CField
▶CFields
CProperties
CFilterFactory Produces and initializes UDFilters to transform input data before parsing
CFIunion
CFunctionFactory
CIntermediateAggs A wrapper around a single intermediate aggregate value
CIterativeSourceFactory Source factory that works with a SourceIterator to produce UDSources
CLengthBuffer
CLibraryRegistrar
CModel
CMultiPhaseTransformFunctionFactory Interface for declaring parameters and return types for, and instantiating, an associated multi-phase transform function. This class is similar to, but not a subclass of, TransformFunctionFactory
CMultipleIntermediateAggs A wrapper around multiple intermediate aggregates
CNodeSpecifyingPlanContext Interface that allows storage of query-plan state, when different parts of query planning take place on different computers
COpenOptions
CParallelismInfo
CParamReader Provides read access to a set of named parameters. This class provides type-specific methods to retrieve values
CParamWriter Provides write access to a set of named parameters. This class extends ParamReader to add type-specific methods to write values
CParserFactory Produces and initializes UDParsers to parse input into tuples
CPartitionOrderColumnInfo Represents the partition by and order by column information for each phase in a multi-phase transform function
CPartitionReader Iterator-based read interface over all input data in a single partition. Automatically fetches data a block-at-a-time, as needed
CPartitionWriter Provides an iterator-based write interface over output data for a single partition. Automatically makes space a block-at-a-time, as needed
CPartitionWriterColumn
CPartitionWriterColumns PartitionWriterColumns allow column-by-column access to PartitionWriter data
CPartitionWriterNumericColumn
CPartitionWriterStringColumn
CPartitionWriterUuidColumn
CPerColumnParamReader A wrapper around a map from column to ParamReader
CPlanContext 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
CPortion
CRejectedRecord
CScalarFunction Interface for User-Defined Scalar Function (UDSF). A UDSF produces a single value from a row of data
CScalarFunctionFactory Interface for declaring parameters and return types for, and instantiating, an associated ScalarFunction

CUDXFactory Parent class for UDx factories; not intended for direct use by applications
CUDXFunction
CUDXObject Base class for Vertica User-Defined extensions (the function classes themselves). Not intended for direct use by applications
CUDxRegistrar
CUnsizedUDSource Base class for UDSource. 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
