◆ 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
srvInterfacea ServerInterface object used to communicate with Vertica
resa VResources object used to tell Vertica what resources are needed by the UDX

Reimplemented from Vertica::UDXFactory.
