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)

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()
