public final class MixedItemSection extends Section
.dex file which consists of a sequence of
OffsettedItem objects, which may each be of a different concrete
class and/or size.
Note: It is invalid for an item in an instance of this class to
have a larger alignment requirement than the alignment of this instance.| Constructor and Description |

|
void |
writeIndexAnnotation(AnnotatedOutput out,
ItemType itemType,
String intro)
Writes an index of contents of the items in this instance of the
given type.

Section.prepare().public void placeItems()
OffsettedItem.place(com.android.dx.dex.file.Section, int) on each item. If an item
does not know its write size before the call to place,
it is that call which is responsible for setting the write size.
This method may only be called once per instance; subsequent calls
will throw an exception.protected void writeTo0(AnnotatedOutput out)
Section.writeTo(com.android.dx.util.AnnotatedOutput) after aligning the cursor of
out and verifying that either the assigned file
offset matches the actual cursor out or that the
file offset was not previously assigned, in which case it gets
assigned to out's cursor.Copyright © 2014. All Rights Reserved.
