@Nullable
public @Nullable BlockNode getBlockByArg(RegisterArg arg)

getBlockByArgIndex

public BlockNode getBlockByArgIndex(int argIndex)

getArg

@NotNull
public @NotNull RegisterArg getArg(int n)

Overrides:

getArg in class InsnNode

getArgByBlock

@Nullable
public @Nullable RegisterArg getArgByBlock(BlockNode block)

removeArg

public boolean removeArg(InsnArg arg)

Overrides:

removeArg in class InsnNode

getArgByBlock

@Nullable
public @Nullable RegisterArg getArgByBlock(IBlock block)

replaceArg

public boolean replaceArg(InsnArg from,
 InsnArg to)

Description copied from class: InsnNode

Replace instruction arg with another using recursive search.

Overrides:

replaceArg in class InsnNode

addArg

public void addArg(InsnArg arg)

Overrides:

addArg in class InsnNode

setArg

public void setArg(int n,
 InsnArg arg)

Overrides:

setArg 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 InsnNode

toString

public String toString()

Overrides:

toString in class InsnNode
