Method Detail

kind

public int kind()

Description copied from class: Quad

Return an integer enumeration of the kind of this Quad. The enumerated values are defined in QuadKind.

Overrides:

kind in class OPER

rename

public Quad rename(QuadFactory qf,
                   TempMap defMap,

Description copied from class: Quad

Create a new Quad identical to the receiver, but with all Temps renamed according to a mapping. The new Quad will have no edges.

The new Quad will come from the specified QuadFactory.

Overrides:

rename in class OPER

accept
