◆ getParameterType()

virtual void Vertica::UDXFactory::getParameterType	(	ServerInterface &	srvInterface,
		SizedColumnTypes &	parameterTypes
	)

inlinevirtualinherited

Function to tell Vertica the name and types of parameters that this function uses. Vertica will use this to warn function callers that certain parameters they provide are not affecting anything, or that certain parameters that are not being set are reverting to default values.

Reimplemented in Vertica::ParserFactory.

◆ getPerInstanceResources() [1/2]

virtual void Vertica::UDLFactory::getPerInstanceResources	(	ServerInterface &	srvInterface,
		VResources &	res
	)

inlinevirtual

Set the resource required for each instance of the UDX Object subclass. Users should override only one of the following methods.

Parameters

srvInterface	a ServerInterface object used to communicate with Vertica
res	a VResources object used to tell Vertica what resources are needed by the UDX

Reimplemented from Vertica::UDXFactory.

◆ getPerInstanceResources() [2/2]

virtual void Vertica::UDLFactory::getPerInstanceResources	(	ServerInterface &	srvInterface,
		VResources &	res,
		const SizedColumnTypes &	inputTypes
	)

inlinevirtual

Set the resource required for each instance of the UDX Object subclass. Users should override only one of the following methods.

Parameters

srvInterface	a ServerInterface object used to communicate with Vertica
res	a VResources object used to tell Vertica what resources are needed by the UDX
argTypes	Provides the data types of arguments that this UDT was called with

Reimplemented from Vertica::UDXFactory.

◆ getUDXFactoryType()

virtual UDXType Vertica::UDXFactory::getUDXFactoryType ( )

pure virtualinherited

Returns: the type of UDX Object instance this factory returns.

Note: User subclasses should use the appropriate subclass of UDXFactory and not override this method on their own.

Implemented in Vertica::UDKeyManagerFactory, Vertica::MultiPhaseTransformFunctionFactory, Vertica::AggregateFunctionFactory, Vertica::AnalyticFunctionFactory, Vertica::TransformFunctionFactory, Vertica::ScalarFunctionFactory, Vertica::ParserFactory, Vertica::FilterFactory, Vertica::IterativeSourceFactory, and Vertica::UDFileSystemFactory.
