public class JSRInlinerAdapter extends MethodNode implements Opcodes
MethodVisitor
that removes JSR instructions and inlines the
referenced subroutines.

visitEnd()
If any JSRs were seen, triggers the inlining process.

visitJumpInsn(int opcode,
Label lbl)
Detects a JSR instruction and sets a flag to indicate we will need to do inlining.

opcode
- the opcode of the type instruction to be visited. This opcode is either IFEQ,
IFNE, IFLT, IFGE, IFGT, IFLE, IF_ICMPEQ, IF_ICMPNE, IF_ICMPLT, IF_ICMPGE, IF_ICMPGT,
IF_ICMPLE, IF_ACMPEQ, IF_ACMPNE, GOTO, JSR, IFNULL or IFNONNULL.lbl
- the operand of the instruction to be visited. This operand is a label that
designates the instruction to which the jump instruction may jump.public void visitEnd()
