Class LineNumber
- public final class LineNumber
This class represents a (PC offset, line number) pair, i.e. a line number in
the source that corresponds to a relative address in the byte code. This
is used for debugging purposes.

LineNumber
public LineNumber()
- Empty constructor, all attributes have to be defined via `setXXX'
methods. Use at your own risk.
LineNumber
public LineNumber(LineNumber c)
- Initialize from another object.
LineNumber
LineNumber(DataInputStream file)
throws java.io.IOException
- Construct object from file stream.
- Parameters:
- file - Input stream
- throw IOException
LineNumber
public LineNumber(int start_pc, int line_number)
- Parameters:
- start_pc - Program Counter (PC) corresponds to
- line_number - line number in source file
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 line number/pc pair to file stream in binary format.
- Parameters:
- file - Output file stream
- throw IOException
getLineNumber
public final int getLineNumber()
- Returns: Corresponding source line
getStartPC
public final int getStartPC()
- Returns: PC in code
setLineNumber
public final void setLineNumber(int line_number)
- Parameters:
- line_number.
setStartPC
public final void setStartPC(int start_pc)
- Parameters:
- start_pc.
toString
public final String toString()
- Returns: String representation
