Field Detail

TRACE

public static boolean TRACE

---

ip

Memory.CodeAddress ip

---

fp

Memory.StackAddress fp

Constructor Detail

StackCodeWalker

public StackCodeWalker(Memory.CodeAddress ip,
                       Memory.StackAddress fp)

Method Detail

getIP

public Memory.CodeAddress getIP()

---

getFP

public Memory.StackAddress getFP()

---

getCode

public Clazz.jq_CompiledCode getCode()

---

getMethod

public Clazz.jq_Method getMethod()

---

getCodeOffset

public int getCodeOffset()

---

getSourceFile

public UTF.Utf8 getSourceFile()

---

getBCIndex

public int getBCIndex()

---

getLineNum

public int getLineNum()

---

gotoNext

public void gotoNext()
              throws java.util.NoSuchElementException

---

hasNext

public boolean hasNext()

Description copied from interface: java.util.Iterator

Tests whether there are elements remaining in the collection. In other words, calling next() will not throw an exception.

Specified by:

hasNext in interface java.util.Iterator

---

next

public java.lang.Object next()
                      throws java.util.NoSuchElementException

Description copied from interface: java.util.Iterator

Obtain the next element in the collection.

Specified by:

next in interface java.util.Iterator

---

remove

public void remove()
            throws java.lang.UnsupportedOperationException

Description copied from interface: java.util.Iterator

Remove from the underlying collection the last element returned by next (optional operation). This method can be called only once after each call to next(). It does not affect what will be returned by subsequent calls to next.

Specified by:

remove in interface java.util.Iterator

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

stackDump

public static void stackDump(Memory.CodeAddress init_ip,
                             Memory.StackAddress init_fp)
