Methods

Modifier and Type	Method and Description
void	appendTo(IntVector v)
int	arrayLength()
int[]	asReferenceArray()
ReferenceArrayFields	clone()
boolean	equals(Object o) default implementation is just an identity check
int	getHeapSize() give an approximation of the heap size in bytes - we assume fields are word aligned, hence the number of values*4 should be good.
int	getReferenceValue(int pos)
Object	getValues()
void	hash(HashData hd)
boolean	isReferenceArray()
protected void	printValue(PrintStream ps, int idx)
void	setReferenceValue(int pos, int newValue)

Method Detail

asReferenceArray

public int[] asReferenceArray()

Overrides:

asReferenceArray in class ArrayFields

printValue

protected void printValue(PrintStream ps,
              int idx)

Specified by:

printValue in class ArrayFields

getValues

public Object getValues()

Specified by:

getValues in class ArrayFields

arrayLength

public int arrayLength()

Specified by:

arrayLength in class ArrayFields

isReferenceArray

public boolean isReferenceArray()

Overrides:

isReferenceArray in class ArrayFields

getHeapSize

public int getHeapSize()

Description copied from class: Fields

give an approximation of the heap size in bytes - we assume fields are word aligned, hence the number of values*4 should be good. Note that this is overridden by ArrayFields (arrays would be packed)

Specified by:

getHeapSize in class ArrayFields

appendTo

public void appendTo(IntVector v)

Specified by:

appendTo in class Fields

clone

public ReferenceArrayFields clone()

Specified by:

clone in class Fields

equals

public boolean equals(Object o)

Description copied from class: Object

default implementation is just an identity check

Specified by:

equals in class Fields

setReferenceValue

public void setReferenceValue(int pos,
                     int newValue)

Overrides:

setReferenceValue in class ArrayFields

getReferenceValue

public int getReferenceValue(int pos)

Overrides:

getReferenceValue in class ArrayFields

hash

public void hash(HashData hd)

Specified by:

hash in class Fields
