enum Vertica::UDXFactory::UDXType

inherited

The type of UDX instance this factory produces

Member Function Documentation

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.

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

inlinevirtualinherited

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 in Vertica::UDLFactory.

Referenced by Vertica::UDXFactory::getPerInstanceResources().

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

inlinevirtualinherited

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 in Vertica::UDLFactory.

void Vertica::UDFileSystemFactory::getPrototype	(	ServerInterface &	srvInterface,
		ColumnTypes &	argTypes,
		ColumnTypes &	returnType
	)

inline

UDFileSystems take no input tuples; as such, their prototype must be empty.

virtual void Vertica::UDFileSystemFactory::getReturnType	(	ServerInterface &	srvInterface,
		const SizedColumnTypes &	argTypes,
		SizedColumnTypes &	returnType
	)

inlinevirtual

UDFileSystems return no output; as such, their prototype must be empty.

virtual UDXType Vertica::UDFileSystemFactory::getUDXFactoryType ( )

inlineprotectedvirtual

Returns: the object type internally used by Vertica

Implements Vertica::UDXFactory.
