AnnotationSetItem

public final class AnnotationSetItem extends OffsettedItem
Set of annotations, where no annotation type appears more than once.

Fields Summary
private static final int
ALIGNMENT
the required alignment for instances of this class
private static final int
ENTRY_WRITE_SIZE
the size of an entry int the set: one {@code uint}
private final com.android.dexgen.rop.annotation.Annotations
annotations
{@code non-null;} the set of annotations
private final AnnotationItem[]
items
{@code non-null;} set of annotations as individual items in an array. Note: The contents have to get sorted by type id before writing.
Constructors Summary
public AnnotationSetItem(com.android.dexgen.rop.annotation.Annotations annotations)
Constructs an instance.
