所有已实现的接口:

InstructionVisitor

public class InstructionSequencesReplacer
extends MultiInstructionVisitor
implements InstructionVisitor

This InstructionVisitor replaces multiple instruction sequences at once.

The replacement sequences are optional, defaulting to the empty sequence, to delete the matched pattern sequences.

构造器详细资料

InstructionSequencesReplacer

public InstructionSequencesReplacer(Constant[] constants,
 Instruction[][][] instructionSequences,
 BranchTargetFinder branchTargetFinder,
 CodeAttributeEditor codeAttributeEditor)

Creates a new InstructionSequencesReplacer.

参数:

constants - any constants referenced by the pattern instructions and replacement instructions.

instructionSequences - the instruction sequences to be replaced, with subsequently the sequence pair index, the patten/replacement index (0 or 1), and the instruction index in the sequence.

branchTargetFinder - a branch target finder that has been initialized to indicate branch targets in the visited code.

codeAttributeEditor - a code editor that can be used for accumulating changes to the code.
