Class ByteBufferLocation

java.lang.Object
  frysk.value.Location
      frysk.value.ByteBufferLocation

Direct Known Subclasses:

ScratchLocation

public class ByteBufferLocation
extends Location

A value's Location, implemented using a ByteBuffer. Largely used for testing (well should be); DWARF code proper uses the PieceLocation.

Field Summary

private ByteBuffer	buffer
private long	offset

Constructor Summary

ByteBufferLocation(ByteBuffer buffer)

ByteBufferLocation(ByteBuffer memory, long offset, long length)

Method Summary

long	getAddress()
protected byte	getByte(long offset) Return the byte at OFFSET.
long	length() The length of the location, in bytes.
protected void	putByte(long offset, byte value) Stores the byte VALUE at OFFSET.
protected Location	slice(long offset, long length) Return a slice of this Location starting at byte OFFSET, and going for LENGTH bytes.
void	toPrint(PrintWriter writer) Print this Location.
String	toString()

slice

protected Location slice(long offset,
                         long length)

Return a slice of this Location starting at byte OFFSET, and going for LENGTH bytes.

Specified by:

slice in class Location

getByte

protected byte getByte(long offset)

Return the byte at OFFSET.

Specified by:

getByte in class Location

putByte

protected void putByte(long offset,
                       byte value)

Stores the byte VALUE at OFFSET.

Specified by:

putByte in class Location

length

public long length()

Description copied from class: Location

The length of the location, in bytes. This MUST be a long (or BigInteger) as a value's size could be bigger than 32-bits.
