Method Detail

itemType

public abstract ItemType itemType()

Returns the item type for this instance.

Returns:

non-null; the item type

writeSize

public abstract int writeSize()

Gets the size of this instance when written, in bytes.

Returns:

>= 0; the write size

addContents

public abstract void addContents(DexFile file)

Populates a DexFile with items from within this instance. This will not add an item to the file for this instance itself (which should have been done by whatever refers to this instance).

Note: Subclasses must override this to do something appropriate.

Parameters:

file - non-null; the file to populate

writeTo

public abstract void writeTo(DexFile file,
                             AnnotatedOutput out)

Writes the representation of this instance to the given data section, using the given DexFile to look things up as needed. If this instance keeps track of its offset, then this method will note the written offset and will also throw an exception if this instance has already been written.

Parameters:

file - non-null; the file to use for reference

out - non-null; where to write to
