Design API

• root.hasPorts()

• root.getPorts(): returns a list of all the ports (see port API below)

• root.hasGenerics()

• root.getGenerics(): returns a list of all the generics (see port API below)

Port API

• port.getDirection()

• port.getType()

• port.hasRange()

• port.hasRangeConstraint()

• port.getRange()

• port.hasInitialValue()

• port.getInitialValue()

Generic API

• generic.hasType()

• generic.getType()

• generic.hasRange()

• generic.hasRangeConstraint()

• generic.getRange()

• generic.hasInitialValue()

• generic.getInitialValue()
