 MethodImplementation methodImplementation)

MutableMethodImplementation

public MutableMethodImplementation(int registerCount)

Method Details

getRegisterCount

public int getRegisterCount()

Description copied from interface: MethodImplementation

Gets the number of registers in this method.

Specified by:

getRegisterCount in interface MethodImplementation

Returns:

The number of register in this method.

getInstructions

@Nonnull
public List<BuilderInstruction> getInstructions()

Description copied from interface: MethodImplementation

Gets the instructions in this method.

Specified by:

getInstructions in interface MethodImplementation

Returns:

An Iterable of the instructions in this method

getTryBlocks

@Nonnull
public List<BuilderTryBlock> getTryBlocks()

Description copied from interface: MethodImplementation

Gets a list of the try blocks defined for this method. Try blocks may overlap freely, and do not need to be strictly nested, as in java. This is a more relaxed requirement than specified by the dex format, where try blocks may not overlap, and must be specified in ascending order. When writing to a dex file, the try blocks will be massaged into the appropriate format. In any region where there are overlapping try blocks, set of exception handlers for the overlapping region will consist of the union of all handlers in any try block that covers that region. If multiple overlapping try blocks define a handler for the same exception type, or define a catch-all handler, then those duplicate handlers must use the same handler offset.

Specified by:

getTryBlocks in interface MethodImplementation

Returns:

A list of the TryBlock items

getDebugItems

@Nonnull
public Iterable<? extends DebugItem> getDebugItems()

Description copied from interface: MethodImplementation

Get a list of debug items for this method. This generally matches the semantics of the debug_info_item in the dex specification, although in an easier to digest form. The addresses of the DebugItems in the returned list will be in non-descending order.

Specified by:

getDebugItems in interface MethodImplementation

Returns:

A list of DebugInfo items
