addPhi

public void addPhi(SSAPhiInstruction phiInstruction)

getPis

public Collection<SSAPiInstruction> getPis()

addPi

public void addPi(SSAPiInstruction piInstruction)

equals

public boolean equals(Object arg0)

Overrides:

equals in class Object

getFirstInstructionIndex

public int getFirstInstructionIndex()

Description copied from interface: IBasicBlock

Get the index of the first instruction in the basic block. The value is an index into the instruction array that contains all the instructions for the method. If the result is < 0, the block has no instructions

Specified by:

getFirstInstructionIndex in interface IBasicBlock<SSAInstruction>

Returns:

the instruction index for the first instruction in the basic block.

getLastInstructionIndex

public int getLastInstructionIndex()

Description copied from interface: IBasicBlock

Get the index of the last instruction in the basic block. The value is an index into the instruction array that contains all the instructions for the method. If the result is < 0, the block has no instructions

Specified by:

getLastInstructionIndex in interface IBasicBlock<SSAInstruction>

Returns:

the instruction index for the last instruction in the basic block

isCatchBlock

public boolean isCatchBlock()

Description copied from interface: IBasicBlock

Return true if the basic block represents a catch block.

Specified by:

isCatchBlock in interface IBasicBlock<SSAInstruction>

Returns:

true if the basic block represents a catch block.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

See Also:

Object.toString()

isExitBlock

public boolean isExitBlock()

Description copied from interface: IBasicBlock

Return true if the basic block represents the unique exit block.

Specified by:

isExitBlock in interface IBasicBlock<SSAInstruction>

Returns:

true if the basic block represents the unique exit block.

isEntryBlock

public boolean isEntryBlock()

Description copied from interface: IBasicBlock

Return true if the basic block represents the unique entry block.

Specified by:

isEntryBlock in interface IBasicBlock<SSAInstruction>

Returns:

true if the basic block represents the unique entry block.

getMethod

public IMethod getMethod()

Specified by:

getMethod in interface IBasicBlock<SSAInstruction>

Returns:

governing method for this block

endsInPEI

public boolean endsInPEI()

endsInReturn

public boolean endsInReturn()

getNumber

public int getNumber()

Description copied from interface: IBasicBlock

Each basic block should have a unique number in its cfg

Specified by:

getNumber in interface IBasicBlock<SSAInstruction>

Returns:

the basic block's number

iterator

public Iterator<SSAInstruction> iterator()

Specified by:

iterator in interface Iterable<SSAInstruction>
