Constructor Detail

CodeItem

public CodeItem(CstMethodRef ref,
                DalvCode code,
                boolean isStatic,
                TypeList throwsList)

Constructs an instance.

Parameters:

ref - non-null; method that this code implements

code - non-null; the underlying code

isStatic - whether this instance is for a static method

throwsList - non-null; list of possibly-thrown exceptions, just used in generating debugging output (listings)

Method Detail

itemType

public ItemType itemType()

Returns the item type for this instance.

Specified by:

itemType in class Item

Returns:

non-null; the item type

addContents

public 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.

Specified by:

addContents in class Item

Parameters:

file - non-null; the file to populate

toString

public String toString()

Overrides:

toString in class Object

toHuman

public String toHuman()

Gets a short human-readable string representing this instance.

Specified by:

toHuman in class OffsettedItem

Returns:

non-null; the human form

getRef

public CstMethodRef getRef()

Gets the reference to the method this instance implements.

Returns:

non-null; the method reference

debugPrint

public void debugPrint(PrintWriter out,
                       String prefix,
                       boolean verbose)

Does a human-friendly dump of this instance.

Parameters:

out - non-null; where to dump

prefix - non-null; per-line prefix to use

verbose - whether to be verbose with the output

place0

protected void place0(Section addedTo,
                      int offset)

Does additional work required when placing an instance. The default implementation of this method is a no-op. If a particular class needs to do something special, then it should override this method. In particular, if this instance did not know its write size up-front, then this method is responsible for setting it.

Overrides:

place0 in class OffsettedItem

Parameters:

addedTo - non-null; the section this instance has been added to

offset - >= 0; the offset from the start of the section where this instance was placed

writeTo0

protected void writeTo0(DexFile file,
                        AnnotatedOutput out)

Performs the actual write of the contents of this instance to the given data section. This is called by OffsettedItem.writeTo(com.android.dx.dex.file.DexFile, com.android.dx.util.AnnotatedOutput), which will have taken care of ensuring alignment.

Specified by:

writeTo0 in class OffsettedItem

Parameters:

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

out - non-null; where to write to
