Field Detail

dst

protected Temp dst

The Temp in which to store the new array reference.

hclass

protected final HClass hclass

Description of array class to create.

dims

protected Temp[] dims

Lengths of each dimension to create.

Constructor Detail

ANEW

public ANEW(QuadFactory qf,
            HCodeElement source,
            Temp dst,
            HClass hclass,
            Temp[] dims)

Creates an ANEW object. ANEW creates an array of the type and number of dimensions indicated by the hclass parameter. Each entry in dims denotes the number of components in a particular dimension of the array. dims[0] corresponds to the left-most dimension. The array class referenced by hclass may have more dimensions than the length of the dims parameter. In that case, only the first dims.length dimensions of the array are created.

Parameters:

dst - the Temp in which to store the new array reference.

hclass - the array class to create.

dims - Temps holding the length of each array dimension.

Method Detail

dst

public Temp dst()

Returns the destination Temp.

hclass

public HClass hclass()

Returns the array class this ANEW will create.

dims

public Temp[] dims()

Returns an array of Temps holding the length of each array dimension.

dims

public Temp dims(int i)

Returns a particular element of the dims array.

dimsLength

public int dimsLength()

Returns the length of the dims array.

def

public Temp[] def()

Returns the Temp defined by this Quad.

Specified by:

def in interface UseDefable

Overrides:

def in class Quad

Returns:

the dst field.

use

public Temp[] use()

Returns the Temps used by this Quad.

Specified by:

use in interface UseDefable

Overrides:

use in class Quad

Returns:

the dims field.

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.

Specified by:

kind in class Quad

rename

public Quad rename(QuadFactory qqf,
                   TempMap defMap,
                   TempMap useMap)

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.

Specified by:
