Method Details

narrowTypeByOp

initBlocks

public void initBlocks(BlockNode curBlock)

Overrides:

initBlocks in class TargetInsnNode

replaceTargetBlock

public boolean replaceTargetBlock(BlockNode origin,
 BlockNode replace)

Overrides:

replaceTargetBlock in class TargetInsnNode

getThenBlock

public BlockNode getThenBlock()

getElseBlock

public BlockNode getElseBlock()

getTarget

public int getTarget()

Overrides:

getTarget in class GotoNode

isSame

public boolean isSame(InsnNode obj)

Description copied from class: InsnNode

'Soft' equals, don't compare arguments, only instruction specific parameters.

Overrides:

isSame in class InsnNode

copy

public InsnNode copy()

Description copied from class: InsnNode

Make copy of InsnNode object.
NOTE: can't copy instruction with result argument (SSA variable can't be used in two different assigns).
Prefer use next methods:

• InsnNode.copyWithoutResult() to explicitly state that result not needed
• InsnNode.copy(RegisterArg) to provide new result arg
• InsnNode.copyWithNewSsaVar(MethodNode) to make new SSA variable for result arg

Overrides:

copy in class GotoNode

toString

public String toString()

Overrides:

toString in class GotoNode
