Method Detail

getResultType

public final AType getResultType()

Description copied from class: Instruction

Gets the stack type of the value produced by this Instruction.

Specified by:

getResultType in class Instruction

Returns:

The AType.

getDirectFlags

public EnumBitSet<InstructionFlag> getDirectFlags()

Description copied from class: Instruction

Any direct flags for this Instruction.

The return value should be cached statically inside the Instruction impl.

Specified by:

getDirectFlags in class Instruction

Returns:

An EnumBitSet representing the flags.

Overrides:

copy in class Instruction

Returns:

The copied instruction.

onDisconnected

protected void onDisconnected()

Overrides:

onDisconnected in class Instruction

getType
