Constructor & Destructor Documentation

◆ PipelineElement()

TTAMachine::PipelineElement::PipelineElement	(	const std::string &	name,
		FunctionUnit &	parentUnit
	)

Constructor.

Pipeline elements are created automatically when pipeline of operation is created. Clients should not create pipeline elements.

Parameters

name	Name of the pipeline element.
parentUnit	The parent unit.

Exceptions

ComponentAlreadyExists	If there exists another pipeline element by the same name in the function unit.
InvalidName	If the given name is not a valid component name.
