LineNumberList

• java.lang.Object
  • com.android.dx.util.FixedSizeList

Fields Summary
public static final LineNumberList	EMPTY non-null; zero-size instance

Constructors Summary
public LineNumberList(int count) Constructs an instance. param count the number of elements to be in the list super(count);

Methods Summary
public static com.android.dx.cf.code.LineNumberList	concat(com.android.dx.cf.code.LineNumberList list1, com.android.dx.cf.code.LineNumberList list2) Returns an instance which is the concatenation of the two given instances. param list1 non-null; first instance param list2 non-null; second instance return non-null; combined instance if (list1 == EMPTY) { // easy case return list2; } int sz1 = list1.size(); int sz2 = list2.size(); LineNumberList result = new LineNumberList(sz1 + sz2); for (int i = 0; i < sz1; i++) { result.set(i, list1.get(i)); } for (int i = 0; i < sz2; i++) { result.set(sz1 + i, list2.get(i)); } return result;
public com.android.dx.cf.code.LineNumberList$Item	get(int n) Gets the indicated item. param n >= 0; which item return null-ok; the indicated item return (Item) get0(n);
public int	pcToLine(int pc) Gets the line number associated with the given address. param pc >= 0; the address to look up return >= -1; the associated line number, or -1 if none is known /* * Line number entries don't have to appear in any particular * order, so we have to do a linear search. TODO: If * this turns out to be a bottleneck, consider sorting the * list prior to use. */ int sz = size(); int bestPc = -1; int bestLine = -1; for (int i = 0; i < sz; i++) { Item one = get(i); int onePc = one.getStartPc(); if ((onePc <= pc) && (onePc > bestPc)) { bestPc = onePc; bestLine = one.getLineNumber(); if (bestPc == pc) { // We can't do better than this break; } } } return bestLine;
public void	set(int n, com.android.dx.cf.code.LineNumberList$Item item) Sets the item at the given index. param n >= 0, < size(); which element param item non-null; the item if (item == null) { throw new NullPointerException("item == null"); } set0(n, item);
public void	set(int n, int startPc, int lineNumber) Sets the item at the given index. param n >= 0, < size(); which element param startPc >= 0; start pc of this item param lineNumber >= 0; corresponding line number set0(n, new Item(startPc, lineNumber));
