Constructor Detail

LineNumberGen

public LineNumberGen(InstructionHandle ih,
                     int src_line)

Create a line number.

Parameters:

ih - instruction handle to reference

Method Detail

containsTarget

public boolean containsTarget(InstructionHandle ih)

Description copied from interface: InstructionTargeter

Checks whether this targeter targets the specified instruction handle.

Specified by:

containsTarget in interface InstructionTargeter

Returns:

true, if ih is target of this line number

updateTarget

public void updateTarget(InstructionHandle old_ih,
                         InstructionHandle new_ih)

Description copied from interface: InstructionTargeter

Replaces the target of this targeter from this old handle to the new handle.

Specified by:

updateTarget in interface InstructionTargeter

Parameters:

old_ih - old target

new_ih - new target

getLineNumber

public LineNumber getLineNumber()

Get LineNumber attribute . This relies on that the instruction list has already been dumped to byte code or or that the `setPositions' methods has been called for the instruction list.

setInstruction

public void setInstruction(InstructionHandle instructionHandle)

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

getInstruction

public InstructionHandle getInstruction()

setSourceLine

public void setSourceLine(int src_line)

getSourceLine

public int getSourceLine()
