ProtoIdsSection

public final class ProtoIdsSection extends UniformItemSection
Proto (method prototype) identifiers list section of a {@code .dex} file.

Fields Summary
private final TreeMap
protoIds
{@code non-null;} map from method prototypes to {@link ProtoIdItem} instances
Constructors Summary
public ProtoIdsSection(DexFile file)
Constructs an instance. The file offset is initially unknown.

param
file {@code non-null;} file that this instance is part of

        super("proto_ids", file, 4);

        protoIds = new TreeMap<Prototype, ProtoIdItem>();
Methods Summary
public IndexedItemget(com.android.dexgen.rop.cst.Constant cst)
{@inheritDoc}

        throw new UnsupportedOperationException("unsupported");
public intindexOf(com.android.dexgen.rop.type.Prototype prototype)
Gets the index of the given prototype, which must have been added to this instance.

param
prototype {@code non-null;} the prototype to look up
return
{@code >= 0;} the reference's index

        if (prototype == null) {
            throw new NullPointerException("prototype == null");

        }

        return item.getIndex();
public ProtoIdItemintern(com.android.dexgen.rop.type.Prototype prototype)
Interns an element into this instance.

param
prototype {@code non-null;} the prototype to intern
return
{@code non-null;} the interned reference

        if (prototype == null) {
            throw new NullPointerException("prototype == null");

        }
public voidwriteHeaderPart(com.android.dexgen.util.AnnotatedOutput out)
Writes the portion of the file header that refers to this instance.

param
out {@code non-null;} where to write

        throwIfNotPrepared();

        int sz = protoIds.size();
        int offset = (sz == 0) ? 0 : getFileOffset();
