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)

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)

Specified by:

updateTarget in interface InstructionTargeter

Parameters:

old_ih - old target

new_ih - new target

getLineNumber

public LineNumber getLineNumber(ConstantPoolGen cp)

Deprecated. cp not needed

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.

Parameters:

cp - constant pool

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 ih)

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()
