Constructor Detail

### CodeException

    public CodeException(CodeException c)

  Initialize from another object.

### CodeException

    public CodeException(int start_pc,
                         int end_pc,
                         int handler_pc,
                         int catch_type)

Parameters:
  `start_pc` - Range in the code the exception handler is active, start_pc is inclusive while
  `end_pc` - is exclusive
  `handler_pc` - Starting address of exception handler, i.e., an offset from start of code.
  `catch_type` - If zero the handler catches any exception, otherwise it points to the exception class which is to be caught.

Method Detail

### accept

    public void accept(Visitor v)

  Called by objects that are traversing the nodes of the tree implicitely defined by the contents of a Java class. I.e., the hierarchy of methods, fields, attributes, etc. spawns a tree of objects.

  Specified by:
    `accept` in interface `Node`
  Parameters:
    `v` - Visitor object

### dump

    public final void dump(java.io.DataOutputStream file)
                    throws java.io.IOException

  Dump code exception to file stream in binary format.

  Parameters:
    `file` - Output file stream
  Throws:
    `java.io.IOException`

### getCatchType

    public final int getCatchType()

  Returns:
    0, if the handler catches any exception, otherwise it points to the exception class which is to be caught.

### getEndPC

    public final int getEndPC()

  Returns:
    Exclusive end index of the region where the handler is active.

### getHandlerPC

    public final int getHandlerPC()

  Returns:
    Starting address of exception handler, relative to the code.

### getStartPC

    public final int getStartPC()

  Returns:
    Inclusive start index of the region where the handler is active.

### setCatchType

    public final void setCatchType(int catch_type)

### setEndPC

    public final void setEndPC(int end_pc)

  Parameters:
    `end_pc` - end of handled block

### setHandlerPC

    public final void setHandlerPC(int handler_pc)

  Parameters:
    `handler_pc` - where the actual code is

### setStartPC

    public final void setStartPC(int start_pc)

  Parameters:
    `start_pc` - start of handled block

### toString

    public final java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`
  Returns:
    String representation.

### toString

    public final java.lang.String toString(ConstantPool cp,
                                           boolean verbose)

  Returns:
    String representation.

### toString

    public final java.lang.String toString(ConstantPool cp)

### copy

    public CodeException copy()

  Returns:
    deep copy of this object
