LocalVariableList

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

Fields Summary
public static final LocalVariableList	EMPTY {@code non-null;} zero-size instance

Constructors Summary
public LocalVariableList(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.LocalVariableList	concat(com.android.dx.cf.code.LocalVariableList list1, com.android.dx.cf.code.LocalVariableList list2) Returns an instance which is the concatenation of the two given instances. The result is immutable. param list1 {@code non-null;} first instance param list2 {@code non-null;} second instance return {@code non-null;} combined instance if (list1 == EMPTY) { // easy case return list2; } int sz1 = list1.size(); int sz2 = list2.size(); LocalVariableList result = new LocalVariableList(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)); } result.setImmutable(); return result;
public com.android.dx.cf.code.LocalVariableList$Item	get(int n) Gets the indicated item. param n {@code >= 0;} which item return {@code null-ok;} the indicated item return (Item) get0(n);
public com.android.dx.cf.code.LocalVariableList$Item	itemToLocal(com.android.dx.cf.code.LocalVariableList$Item item) Gets the local variable information in this instance which matches the given {@link com.android.dx.cf.code.LocalVariableList.Item} in all respects but the type descriptor and signature, if any. param item {@code non-null;} local variable information to match return {@code null-ok;} the corresponding local variable information stored in this instance, or {@code null} if there is no matching information int sz = size(); for (int i = 0; i < sz; i++) { Item one = (Item) get0(i); if ((one != null) && one.matchesAllButType(item)) { return one; } } return null;
public static com.android.dx.cf.code.LocalVariableList	mergeDescriptorsAndSignatures(com.android.dx.cf.code.LocalVariableList descriptorList, com.android.dx.cf.code.LocalVariableList signatureList) Returns an instance which is the result of merging the two given instances, where one instance should have only type descriptors and the other only type signatures. The merged result is identical to the one with descriptors, except that any element whose {name, index, start, length} matches an element in the signature list gets augmented with the corresponding signature. The result is immutable. param descriptorList {@code non-null;} list with descriptors param signatureList {@code non-null;} list with signatures return {@code non-null;} the merged result int descriptorSize = descriptorList.size(); LocalVariableList result = new LocalVariableList(descriptorSize); for (int i = 0; i < descriptorSize; i++) { Item item = descriptorList.get(i); Item signatureItem = signatureList.itemToLocal(item); if (signatureItem != null) { CstString signature = signatureItem.getSignature(); item = item.withSignature(signature); } result.set(i, item); } result.setImmutable(); return result;
public com.android.dx.cf.code.LocalVariableList$Item	pcAndIndexToLocal(int pc, int index) Gets the local variable information associated with a given address and local index, if any. Note: In standard classfiles, a variable's start point is listed as the address of the instruction just past the one that sets the variable. param pc {@code >= 0;} the address to look up param index {@code >= 0;} the local variable index return {@code null-ok;} the associated local variable information, or {@code null} if none is known int sz = size(); for (int i = 0; i < sz; i++) { Item one = (Item) get0(i); if ((one != null) && one.matchesPcAndIndex(pc, index)) { return one; } } return null;
public void	set(int n, com.android.dx.cf.code.LocalVariableList$Item item) Sets the item at the given index. param n {@code >= 0, < size();} which element param item {@code non-null;} the item if (item == null) { throw new NullPointerException("item == null"); } set0(n, item);
public void	set(int n, int startPc, int length, com.android.dx.rop.cst.CstString name, com.android.dx.rop.cst.CstString descriptor, com.android.dx.rop.cst.CstString signature, int index) Sets the item at the given index. Note: At least one of {@code descriptor} or {@code signature} must be passed as non-null. param n {@code >= 0, < size();} which element param startPc {@code >= 0;} the start pc of this variable's scope param length {@code >= 0;} the length (in bytecodes) of this variable's scope param name {@code non-null;} the variable's name param descriptor {@code null-ok;} the variable's type descriptor param signature {@code null-ok;} the variable's type signature param index {@code >= 0;} the variable's local index set0(n, new Item(startPc, length, name, descriptor, signature, index));
