Constructor Details

JSRInlinerAdapter

public JSRInlinerAdapter(MethodVisitor mv,
 int access,
 String name,
 String desc,
 String signature,
 String[] exceptions)

Creates a new JSRInliner.

Parameters:

mv - the MethodVisitor to send the resulting inlined method code to (use null for none).

access - the method's access flags (see Opcodes). This parameter also indicates if the method is synthetic and/or deprecated.

name - the method's name.

desc - the method's descriptor (see Type).

signature - the method's signature. May be null.

exceptions - the internal names of the method's exception classes (see getInternalName). May be null.

Method Details

visitJumpInsn

public void visitJumpInsn(int opcode,
 Label lbl)

Detects a JSR instruction and sets a flag to indicate we will need to do inlining.

Specified by:

visitJumpInsn in interface MethodVisitor

Overrides:

visitJumpInsn in class MethodNode

Parameters:

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.

visitEnd

public void visitEnd()

If any JSRs were seen, triggers the inlining process. Otherwise, forwards the byte codes untouched.

Specified by:

visitEnd in interface MethodVisitor

Overrides:

visitEnd in class MemberNode
