public class DisplayRealType

extends RealType

DisplayRealType is the class for display real scalar types. ScalarMaps map ScalarTypes to DisplayRealType. A fixed set is defined by the system, users may add others.

Method Detail

getIndex

public int getIndex()

get the index of this in DisplayRealTypeVector; insert this into the Vector if it isn't already

Returns:

the index of this in DisplayRealTypeVector

getCount

public static int getCount()

Returns:

the number of DisplayRealTypes in DisplayRealTypeVector

getTuple

public DisplayTupleType getTuple()

Returns:

the unique DisplayTupleType that this DisplayRealType is a component of, or return null if it is not a component of any DisplayTupleType

getTupleIndex

public int getTupleIndex()

Returns:

index of this as component of a DisplayTupleType (-1 if it isn't a component of any DisplayTupleType)

setTuple

public void setTuple(DisplayTupleType t,
