| public java.lang.String | getDescriptor()Gets the descriptor string.

| public StdTypeList | getParameterFrameTypes()Gets the list of frame types corresponding to the list of parameter
types. The difference between the two lists (if any) is that all
"intlike" types (see {@link Type#isIntlike}) are replaced by
{@link Type#INT}.

| public int | hashCode(){@inheritDoc}
return descriptor.hashCode();

| public static com.android.dx.rop.type.Prototype | intern(java.lang.String descriptor)Returns the unique instance corresponding to the
given method descriptor. See vmspec-2 sec4.3.3 for details on the
field descriptor syntax.

| public static com.android.dx.rop.type.Prototype | intern(java.lang.String descriptor, Type definer, boolean isStatic, boolean isInit)Interns an instance, adding to the descriptor as necessary based
on the given definer, name, and flags. For example, an init
method has an uninitialized object of type {@code definer}
as its first argument.

{@code int}s along with the given return type
// Make the descriptor...
StringBuffer sb = new StringBuffer(100);

| private static Type[] | makeParameterArray(java.lang.String descriptor)Helper for {@link #intern} which returns an empty array to
populate with parsed parameter types, and which also ensures
that there is a '(' at the start of the descriptor and a
single ')' somewhere before the end.

| private static com.android.dx.rop.type.Prototype | putIntern(com.android.dx.rop.type.Prototype desc)Puts the given instance in the intern table if it's not already
there. If a conflicting value is already in the table, then leave it.
Return the interned value.

| public java.lang.String | toString(){@inheritDoc}
return descriptor;
|
| public com.android.dx.rop.type.Prototype | withFirstParameter(Type param)Returns a new interned instance, which is the same as this instance,
except that it has an additional parameter prepended to the original's
argument list.
String newDesc = "(" + param.getDescriptor() + descriptor.substring(1);
StdTypeList newParams = parameterTypes.withFirst(param);
