CodeException
public CodeException()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
CodeException
public CodeException(CodeException c)
- Initialize from another object.
CodeException
CodeException(DataInputStream file)
throws java.io.IOException
- Construct object from file stream.
- Parameters:
- file - Input stream
- throw IOException
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.
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.
- Parameters:
- v - Visitor object
dump
public final void dump(DataOutputStream file)
throws java.io.IOException
- Dump code exception to file stream in binary format.
- Parameters:
- file - Output file stream
- throw IOException
getCatchType
public final int getCatchType()
- Returns: Zero, 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)
- Parameters:
- catch_type.
setEndPC
public final void setEndPC(int end_pc)
- Parameters:
- end_pc.
setHandlerPC
public final void setHandlerPC(int handler_pc)
- Parameters:
- handler_pc.
setStartPC
public final void setStartPC(int start_pc)
- Parameters:
- start_pc.
toString
