Class InterfaceListPointer

java.lang.Object
  harpoon.Util.Tuple
      harpoon.Interpret.Tree.InterfaceListPointer

All Implemented Interfaces:

Serializable, Comparable

public class InterfaceListPointer
extends Tuple

The InterfaceListPointer is used to representing a pointer to a list of interfaces. The pointers of this type resides inside the blocks of class data allocated by the class loader.

Method Detail

add

public harpoon.Interpret.Tree.Pointer add(long offset)

Adds the specified parameter to this ClazPointer's offset

equals

public boolean equals(Object obj)

Returns true if obj is an InterfaceListPointer which points to the same location as this InterfaceListPointer.

Overrides:

equals in class Tuple

getBase

public Object getBase()

Returns an InterfaceList representing the base of this InterfaceListPointer.

getOffset

public long getOffset()

Returns the offset of this ClazPointer.

getValue

public Object getValue()

Dereferences this InterfaceListPointer and returns the value it points to.

isConst

public boolean isConst()

Always returns false.

isDerived

public boolean isDerived()

Always returns false.

kind

public int kind()

Returns an integer enumeration of the kind of this Pointer. The enumerated values are public fields of the Pointer class.

updateValue

public void updateValue(Object obj)

Throws an error, as the program is not supposed to modify static class data

toString

public String toString()

Returns a human-readable representation of this InterfaceListPointer.

Overrides:

toString in class Tuple
