Constructor Details

LineNumberNode

public LineNumberNode(int line,
                      LabelNode start)
Constructs a new LineNumberNode.
Parameters:
line - a line number. This number refers to the source file from which the class was compiled.
start - the first instruction corresponding to this line number.

Method Details

accept

public void accept(MethodVisitor mv)
Makes the given code visitor visit this instruction.
Overrides:
accept in interface AbstractInsnNode
Parameters:

clone

public AbstractInsnNode clone(Map labels)
Returns a copy of this instruction.
Overrides:
clone in interface AbstractInsnNode
Parameters:
labels - a map from LabelNodes to cloned LabelNodes.
Returns:
a copy of this instruction. The returned instruction does not belong to any InsnList.

getType

public int getType()
Returns the type of this instruction.
Overrides:
getType in interface AbstractInsnNode
Returns:
the type of this instruction, i.e. one the constants defined in this class.
