com.ibm.wala.dalvik.ipa.callgraph.androidModel.structure.AbstractAndroidModel

com.ibm.wala.dalvik.ipa.callgraph.androidModel.structure.SequentialAndroidModel

public final class SequentialAndroidModel
extends AbstractAndroidModel

Functions get called once in sequential order.

No loops are inserted into the model.

This model should not be particular useful in practice. However it might come in handy for debugging purposes or as a skeleton for an other Model.

Constructor Details

SequentialAndroidModel

public SequentialAndroidModel(VolatileMethodSummary body,
 TypeSafeInstructionFactory insts,
 SSAValueManager paramManager,
 Iterable<? extends Entrypoint> entryPoints)

Parameters:

body - The MethodSummary to add instructions to

insts - Will be used to generate the instructions

Method Details

enterAT_FIRST

protected int enterAT_FIRST(int PC)

Does not insert any special handling.

Gets called when Label ExecutionOrder.AT_FIRST got stepped over.

In most cases you don't want to invoke this function directly but to use enter(ExecutionOrder.AT_FIRST, int) instead.

Side effects: currentSection is updated, instructions are inserted into the body

Overrides:

enterAT_FIRST in class AbstractAndroidModel

Parameters:

PC - Program Counter instructions shall be placed at. In most cases you'll simply pass body.getNextProgramCounter()

Returns:

Program Counter after insertion of the code

enterBEFORE_LOOP

protected int enterBEFORE_LOOP(int PC)

Does not insert any special handling.

Gets called when Label ExecutionOrder.BEFORE_LOOP got stepped over.

In most cases you don't want to invoke this function directly but to use enter(ExecutionOrder.BEFORE_LOOP, int) instead

Side effects: currentSection is updated, instructions are inserted into the body

Overrides:

enterBEFORE_LOOP in class AbstractAndroidModel

Parameters:

PC - Program Counter instructions shall be placed at. In most cases you'll simply pass body.getNextProgramCounter()

Returns:

Program Counter after insertion of the code

enterSTART_OF_LOOP

protected int enterSTART_OF_LOOP(int PC)

Does not insert any special handling.

Gets called when Label ExecutionOrder.START_OF_LOOP got stepped over.

In most cases you don't want to invoke this function directly but to use enter(ExecutionOrder.START_OF_LOOP, int) instead

Side effects: currentSection is updated, instructions are inserted into the body

Overrides:

enterSTART_OF_LOOP in class AbstractAndroidModel

Parameters:

PC - Program Counter instructions shall be placed at. In most cases you'll simply pass body.getNextProgramCounter()

Returns:

Program Counter after insertion of the code

enterMIDDLE_OF_LOOP

protected int enterMIDDLE_OF_LOOP(int PC)

Does not insert any special handling.

Gets called when Label ExecutionOrder.MIDDLE_OF_LOOP got stepped over.

In most cases you don't want to invoke this function directly but to use enter(ExecutionOrder.MIDDLE_OF_LOOP, int) instead

Side effects: currentSection is updated, instructions are inserted into the body

Overrides:

enterMIDDLE_OF_LOOP in class AbstractAndroidModel

Parameters:

PC - Program Counter instructions shall be placed at. In most cases you'll simply pass body.getNextProgramCounter()

Program Counter after insertion of the code

enterMULTIPLE_TIMES_IN_LOOP

protected int enterMULTIPLE_TIMES_IN_LOOP(int PC)

Does not insert any special handling.

Gets called when Label ExecutionOrder.MULTIPLE_TIMES_IN_LOOP got stepped over.

In most cases you don't want to invoke this function directly but to use enter(ExecutionOrder.MULTIPLE_TIMES_IN_LOOP, int) instead

Side effects: currentSection is updated, instructions are inserted into the body

Overrides:

enterMULTIPLE_TIMES_IN_LOOP in class AbstractAndroidModel

Parameters:
