doPutfield

public void doPutfield(JStackFrame frame,
                       JField field)

Does the putfield operations on the specified stack frame. This operation pop a value and an object reference. Then, it sets the specified field of the object with the popped value.

Parameters:

frame - the current frame of a thread

field - a JField object describing a field

doGetfield

public void doGetfield(JStackFrame frame,
                       JField field)

Does the getfield operations on the specified stack frame. This operation pop an object reference. Then, it sets the specified field of the object with the popped value.

Parameters:

frame - the current stack frame of a thread

field - a JField object describing the field to be pushed onto the stack frame

doPutstatic

public void doPutstatic(JStackFrame frame,
                        JField field)

Does the putstatic operations on the specified stack frame. This operation pop a value from the current stack frame. Then, it sets the specified static field with the popped value.

Parameters:

frame - the current frame of a thread

field - a JField object describing a static field

doGetstatic

public void doGetstatic(JStackFrame frame,
                        JField field)

Does the getstatic operations on the specified stack frame. This operation push onto the current stack frame the value of the specified static field.

Parameters:

frame - the current stack frame of a thread

field - a JField object describing a static field

arrayCopy

public void arrayCopy(JArray src,
                      int srcPos,
                      JArray dest,
                      int destPos,
                      int length)

Copies an array from the specified source array, beginning at the specified position, to the specified position of the destination array. A subsequence of array components are copied from the source array referenced by src to the destination array referenced by dest. The number of components copied is equal to the length argument. The components at positions srcPos through srcPos+length-1 in the source array are copied into positions destPos through destPos+length-1, respectively, of the destination array.

Parameters:

src - the source array.

srcPos - starting position in the source array.

dest - the destination array.

destPos - starting position in the destination data.

length - the number of array elements to be copied.

fieldCopy

public void fieldCopy(JField field,
                      JClassInstance src,
                      JClassInstance dest)

Copies the float value of the specified field from the specified source class instance to the specified class instance destination.

Parameters:

field - the float field whose the value have to be copied

src - the source class instance

dest - the destination class instance

toString

public java.lang.String toString()

Returns a String representation of this class.

Overrides:

toString in class java.lang.Object

copyValue

public void copyValue(JHeap srcHeap,
                      int src,
                      JHeap destHeap,
                      int dest)
