Constructor Detail

ForLoop

public ForLoop(int start,
               int end,
               int reg)

constructs a for loop information block

Parameters:

start - the start of the for loop

end - the end of the for loop

reg - the loop register

Method Detail

getLoopStart

public int getLoopStart()

get the start pc of the loop

Returns:

the start pc of the loop

getLoopEnd

public int getLoopEnd()

get the end pc of the loop

Returns:

the end pc of the loop

getLoopReg

public int getLoopReg()

get the loop register

Returns:

the loop register

setLoopState

public void setLoopState(ListIndexedIterating.LoopState state)

sets the current state of the for loop

Parameters:

state - the new state

getLoopState

public ListIndexedIterating.LoopState getLoopState()

get the current phase of the for loop

Returns:

the current state

setLoopRegLoaded

public void setLoopRegLoaded(boolean loaded)

mark that the loop register has been loaded with an iload instruction

Parameters:

loaded - the flag of whether the loop register is loaded

getLoopRegLoaded

public boolean getLoopRegLoaded()

returns whether the loop register is on the top of the stack

Returns:

whether the loop register is on the top of the stack

isSecondItem

public boolean isSecondItem(edu.umd.cs.findbugs.OpcodeStack.Item itm)

returns whether this is the second time the loop register is found

Parameters:

itm - the item on the stack

Returns:

whether this is the second time the loop register is found
