All Implemented Interfaces:

ToHuman

public final class PositionList
extends FixedSizeList

List of source position entries. This class includes a utility method to extract an instance out of a DalvInsnList.

Nested Class Summary

static class

PositionList.Entry Entry in a position list.

Field Summary

static PositionList	EMPTY non-null; empty instance
static int	IMPORTANT constant for make(com.android.dx.dex.code.DalvInsnList, int) to indicate that only "important" position information should be returned.
static int	LINES constant for make(com.android.dx.dex.code.DalvInsnList, int) to indicate that only line number transitions should be returned
static int	NONE constant for make(com.android.dx.dex.code.DalvInsnList, int) to indicate that no actual position information should be returned

Constructor Summary

PositionList(int size)
Constructs an instance.

Method Summary

PositionList.Entry	get(int n) Gets the element at the given index.
static PositionList	make(DalvInsnList insns, int howMuch) Extracts and returns the source position information out of an instruction list.
void	set(int n, PositionList.Entry entry) Sets the entry at the given index.

Constructor Detail

PositionList

public PositionList(int size)

Constructs an instance. All indices initially contain null.

Parameters:

size - >= 0; the size of the list

Method Detail

make

public static PositionList make(DalvInsnList insns,
                                int howMuch)

Extracts and returns the source position information out of an instruction list.

Parameters:

insns - non-null; instructions to convert

howMuch - how much information should be included; one of the static constants defined by this class

Returns:

non-null; the positions list

get

public PositionList.Entry get(int n)

Gets the element at the given index. It is an error to call this with the index for an element which was never set; if you do that, this will throw NullPointerException.

Parameters:

n - >= 0, < size(); which index

Returns:

non-null; element at that index

set

public void set(int n,
                PositionList.Entry entry)

Sets the entry at the given index.

Parameters:

n - >= 0, < size(); which index

entry - non-null; the entry to set at n
